Choosing Between an Inverter and Solar Inverter: A Homeowner’s Guide

About one in three Australian homes now have rooftop solar. Are you thinking of joining the club? If so, you’d be making a smart move! Solar energy is one of the most effective ways to cut your power bills.

You’ve likely done your research on solar panels, but what about inverters? This little box makes solar panels useful. No inverter? No power to your fridge, lights, or TV!

Not all inverters are the same. A regular inverter and a solar inverter have different jobs, and picking the wrong one could mean wasting energy—or worse—wasting money.

What are the differences between the two, how can you choose the right inverter, and why is Australian-owned iStore a name you can trust when it comes to powering your home with solar? Let’s find out!

What Is an Inverter?

A regular inverter is a device that converts direct current (DC) electricity from a battery, car, generator, or off-grid system into alternating current (AC).

Most household appliances run on AC power. So, if you have a battery or another source producing DC power, you’ll need an inverter to make that electricity usable in your home.

How Does an Inverter Work?

DC power flows in one direction, while AC power switches direction rapidly, which is the kind of electricity that comes through your power points. A regular inverter uses internal electronics to convert the one-way flow of DC into the back-and-forth flow of AC, so your home’s devices can run smoothly and safely.

In non-solar setups, you can use these inverters to

• Power appliances during blackouts with stored battery power from backup systems.
• Run devices from a car or portable batteries while camping, in a caravan, or on a boat.
• Support off-grid living in remote homes or properties with generators or battery banks. 

What Is a Solar Inverter?

When solar panels collect sunlight, they produce electricity in the form of direct current. A solar inverter converts this DC electricity into AC electricity. Without a solar inverter, the energy from solar panels wouldn’t be compatible with appliances or the power grid.

How Does a Solar Inverter Work?

In a typical grid-tied residential solar system, a solar inverter constantly monitors how much electricity the home needs. It sends the converted AC power straight to appliances first. 

If your solar panels produce more energy than your home needs, the inverter routes that extra electricity back into the power grid. Your electricity provider usually gives you credits for the exported energy through a feed-in tariff.

A solar inverter can also work with solar batteries to store excess DC electricity generated during the day. When your home needs power at night or during cloudy weather, the inverter draws this energy from the batteries.

Solar Inverter Benefits for Your Home

Energy Efficiency

With a solar inverter converting solar energy into usable power for your home instantly, you can run your appliances during the day without relying on grid electricity. 

Any extra power your home doesn’t use is sent to the grid. If you have a solar battery, that excess energy can be stored for later, so you can keep using solar power at night or during cloudy weather instead of switching to grid power.

Some solar inverter models come with smart features that track your usage and adjust output to match your needs. That means less waste, lower power bills, and more control over how your home uses energy.

Cost Savings

Using solar energy allows you to rely less on electricity from the grid, which translates to lower electricity usage charges.

Your electricity provider may pay you through feed-in tariffs for any extra solar energy you don’t use and send back to the grid. Over time, these savings can add up and help offset the cost of your solar setup.

Sustainability

Choosing a solar inverter supports a more sustainable way of living and a cleaner energy future for Australia.

When you use solar energy, you reduce your reliance on electricity that comes from fossil fuels like coal and gas. The results? Fewer carbon emissions and a smaller impact on the environment.

In 2024, rooftop solar made up 12.4% of all solar electricity generated in the country, up from 11.2% in 2023. More and more households are contributing to Australia’s clean energy, and you can too!

Reliability

A solar inverter makes your home’s energy setup more reliable by keeping your power supply steady and managing how and when solar energy is used. 

In off-grid or hybrid setups with backup generators or battery storage, the inverter can automatically switch between solar, battery, and generator power. That way, your home stays powered even if the weather changes or there’s a grid outage.

Your EV is parked, your battery is low, and your phone tells you it will take hours to charge at the nearest public charger. It’s a little ironic—driving into the future, only to be stuck waiting on yesterday’s infrastructure!

A home 3 phase EV charger changes the game. Fast, reliable, and ready when you are. 

iStore EV chargers are built for Aussie homes, priced to suit real budgets, and engineered for effortless charging.

Let’s explore how to choose the best home EV charger in Australia.

What is an EV Charger?

An EV charger is a device that uses electricity from your home’s power supply to charge the battery in your electric vehicle (EV) so you can drive it.

Why a Home EV Charger Is Essential for Australian EV Owners

Public charging stations are handy in a pinch, but they’re not always practical. Queues and slow charging speeds add up to wasted time. A home EV charger puts you back in control. Just plug in overnight and wake up to a full battery. 

This convenience is even more important in suburban and regional areas of Australia, where public chargers can be few and far between. With a home charger, you’re not relying on limited infrastructure or planning trips around charge stops. Your garage becomes your personal charging station.

Then there are the long-term savings. Charging at home is often cheaper than using public stations, especially if you plug in during off-peak hours when electricity demand is lower and rates are reduced, like late at night or early in the morning. 

Pair your EV charger with rooftop solar, and you can drive on sunshine, cutting your energy costs even further and reducing your carbon footprint!

EV Charger Types

Level 1 Chargers

Home EV chargers typically use alternating current (AC) to charge vehicles. 

Level 1 AC chargers that often come with an EV plug into a standard 230-volt (V) household outlet and typically deliver up to 2.4 kilowatts (kW) of power. 

They provide a driving range of around 8–15 km per hour of charging and can take up to 20 hours to fully charge a vehicle. This slower charging rate makes them suitable for overnight charging if you drive short distances daily.

Level 2 Chargers

Level 2 AC chargers require a dedicated 240 V circuit and professional installation. They add about 30–40 km of driving range per hour and can take 4–8 hours to charge an EV fully. This faster charging speed is ideal for longer daily commutes and households with multiple EVs. 

These chargers are available in single-phase (up to 7.4 kW) or three-phase (up to 22 kW). Most homes in Australia use single-phase power, which is fast enough for overnight charging. However, if your home has three-phase power—common in newer or larger properties—you can charge even faster.

Dumb vs Smart Chargers

“Dumb” EV chargers simply deliver power to your EV. They

• Don’t have any smart features or app control.
• Are easier to install and less expensive.
• Charge at full power the moment they’re connected, regardless of electricity pricing or solar availability.
• Are suitable for EV owners needing a basic charging solution.

Smart EV chargers do much more than just charge your EV. They

• Optimise energy usage by adjusting charging times based on grid demand, solar availability, and your electricity tariff schedule.
• Reduce electricity costs thanks to their energy efficiency. 
• Connect to the internet to monitor charging in real-time, set schedules, track energy usage, and receive notifications through an app.
• Are suitable for EV owners wanting cost-effective charging or using rooftop solar.

Key Features To Look For in the Best Home EV Charger in Australia

1. Compatibility: The charger must be compatible with your EV’s plug type and charging capacity. 
2. Charging Speed: Look for a charger that matches your daily driving needs. Most Level 2 chargers offer between 7.4 kW and 22 kW, which can significantly reduce charging times compared to a standard plug.
3. Installation Requirements: Check if your home has single-phase or three-phase power. Some chargers also require a dedicated circuit or additional switchboard space, so confirm if any upgrades are needed before purchasing.
4. Affordability: Weigh up the upfront cost of the charger with the long-term value. Features like smart charging, solar integration, or load balancing may cost more upfront but can save you money over time.
5. Safety Features: Look for safety certifications, built-in protection against overvoltage or overheating, and weatherproof casing for outdoor installation. 
6. Easy to Use: The best chargers are intuitive, with app control, clear indicator lights, and simple plug-in functionality. Wall-mounted units with cable holders also keep things tidy.
7. Sustainability: If you have solar panels or plan to install them, choose a charger that supports solar optimisation. 

Apartment EV Charging and Body Corporate Considerations

Limited access to personal power supply, shared parking spaces, and a lack of installation space can make installing an EV charger in an apartment complex complicated. 

You’ll also likely need approval from your body corporate before any electrical work begins. This process may involve submitting detailed installation plans that show how costs and electricity usage will be managed, and ensuring there is no impact on other residents.

How To Install and Use a Home EV Charger

1. Hire a Licensed Electrician: Home EV charger installation must be done by a licensed electrician. They’ll assess your switchboard, wiring, and power supply, and let you know if any upgrades are needed before installation.
2. Choose the Installation Location: Most chargers are wall-mounted in a garage or carport near where your vehicle is parked. If that’s not possible, some models have pedestal or outdoor mounting options.
3. Connect and Charge: Just plug the charger into your EV, and charging will begin automatically. If you have a smart charger, you can control the start and stop times and schedule off-peak charging using an app.
4. Maintain Your Charger: Keep the unit clean, check for visible wear, and follow any guidelines from your installer or manufacturer.

Longer summers. Rising energy prices. Bigger power bills. 

If you’re building or upgrading a house, solar energy should be at the forefront of your mind to combat these growing pressures.

But solar panels are only half the story. Solar batteries are fast becoming the must-have addition for households that want to store power, use more of their own energy, and reduce reliance on the grid.

Proudly Australian-owned, iStore offers high-performing, reliable, and competitively priced solar batteries for houses in our great country.

Why are solar batteries worth the investment, how do they benefit both builders and homeowners, and why is iStore’s range the ideal choice? We’ll discuss all that and more!

What Is a Solar Battery for a House?

Solar panels generate electricity during the day when the sun is shining. The home immediately uses the electricity it needs to power lights, appliances, and anything else running.

Around midday, when the sun is strongest, solar panels tend to generate more electricity than a household needs. Instead of sending that excess electricity back to the grid, a solar battery stores it.

This battery connects to a solar inverter, which turns solar energy into usable electricity.

Solar panels stop producing power once the sun goes down. At that time, the battery sends the stored energy into the home to keep everything running. If the battery runs low, the house will automatically draw power from the grid as a backup.

Why Solar Batteries Are Essential for Modern Houses

Power Backup

Think of a solar battery as a home’s personal energy reserve. Once the sun goes down, the battery steps in to keep lights on and appliances running.

In the event of a power outage, having backup energy from a solar battery gives peace of mind—no scrambling for candles or worrying about food spoiling!

Builders offering homes with battery backup show homeowners that they’re building with comfort, reliability, and modern living in mind.

Lower Electricity Bills

A solar battery stores the excess energy a home’s solar panels produce during the day so that the home can rely less on the grid and, in turn, pay less for electricity.

In peak hours (typically early mornings and evenings) when electricity rates are higher or on cloudy days when the panels aren’t generating enough energy, a home can use the stored energy from a solar battery instead of expensive grid electricity.

For homeowners, this means lower bills and more control over their energy use. For builders, it’s a great way to offer clients long-term savings and boost the value of a home.

Sustainability

Australian homes significantly contribute to the nation’s carbon emissions, accounting for over 10% of total emissions and around 24% of overall electricity consumption. This substantial reliance on fossil fuels, which release greenhouse gases, drives climate change.​

Integrating solar batteries into residential properties offers a practical solution to this issue. Enabling homeowners to utilise renewable energy even when the sun isn’t shining reduces dependence on fossil fuel-based electricity, leading to a direct decrease in household carbon emissions. 

Homeowners benefit by reducing their carbon footprint and participating in global efforts to combat climate change while enjoying the reliability and cost savings associated with renewable energy.​

Builders incorporating solar batteries into new constructions abide by sustainable building practices and enhance a property’s appeal to environmentally conscious buyers.

Choosing the Right Solar Battery for a House

What should you consider when choosing a solar battery for your home or a client’s?

1. What size battery does the house need?

Check how much energy your household uses daily. You can find this on your electricity bill, usually in kilowatt-hours (kWh). 

For a home under construction, you’ll have to research how much electricity a home of similar size uses. As an example, the average Australian household of four uses about 22kWh a day. 

Choose a battery that can cover the household’s evening and overnight usage—typically around half their daily total. So, for 22kWh usage a day, a 10–15kWh solar battery would be suitable. 

2. Is the battery compatible with the existing solar energy system setup?

If the home already has solar panels and an inverter, you must select a compatible solar battery.  

For systems with a standard string inverter, you may need to install a separate battery inverter to connect a battery. However, if the system already includes a hybrid inverter—which handles both solar and battery inputs—it’s much easier to add a battery.

3. Are the battery’s materials durable and safe?

Choose a battery made from stable, long-lasting materials like lithium iron phosphate. These batteries are known for their safety, thermal stability, and long lifespan, which is especially necessary in Australia’s sometimes harsh climate.

4. Can the battery system be scaled later?

If a home’s energy needs will increase over time, a modular battery system allows the addition of more battery units and storage without replacing the entire setup. This option is perfect for growing families.

5. Is the price reasonable?

Look for value, not just the cheapest option. A good-quality solar battery may cost more upfront but will save users more in the long run with better performance and efficiency.

6. Is the brand reputable?

Research brands with a proven track record, local support, and a solid warranty. A trusted name with good reviews and Australian-based customer service makes all the difference if you need help with the system down the line.

Installation and Maintenance of Solar Batteries for Houses

A professional, certified installer must install a solar battery system to ensure it meets all local building codes and safety regulations and to avoid potential legal and safety issues.​ Proper installation also maximises system performance and efficiency.​

Here’s how the installation process generally goes.

1. Site Assessment: The installer evaluates the home’s current solar setup, electrical system, and space availability to determine the best location and compatibility for the battery. 
2. System Design: They create a tailored plan, specifying the battery size, placement, and integration method with existing solar panels and the inverter.​
3. Permits: They obtain the necessary permits to comply with local regulations and safety standards.
4. Electrical Upgrades (If Needed): The home’s electrical panel may require upgrades to support the new battery system.
5. Battery Mounting: The installer mounts the battery to a wall. Common installation spots are garages, undercover carports, or other areas protected from heat, moisture, and dust. 
6. Electrical Integration: They then connect the battery to the solar inverter and install a safety disconnect, which is a switch that allows homeowners or technicians to quickly and safely shut off power to the solar battery for maintenance and emergency shutdowns.​ 
7. System Configuration and Testing: The installer configures and tests the entire setup to make sure the battery charges and discharges correctly and everything functions safely. ​
   

Once the battery is installed, maintenance is vital to keep it running consistently and safely.

We’ve designed our solar batteries for minimal maintenance.

• Weekly: Monitor the system’s performance through the iStore app, which works via the iStore WLAN dongle. Look for anything unusual, like lower-than-usual charge levels, the battery not discharging when expected, or error notifications.
• Monthly: Check the battery for cracks, dents, corrosion on terminals, loose cables, and signs of water damage, especially if it’s installed outside.
• Every 1–2 Years (Or As Needed): Arrange a professional service every year or two. Contact a certified technician immediately to address any irregularities or issues.​

While a 5kWh battery is insufficient to run an entire house, it can power essential household appliances, such as lights, a refrigerator, and a few electronics, for approximately 6–10 hours. 

A 10kWh solar battery can power essential household appliances for approximately 10–12 hours. 

So, generally speaking, installing two or three 5kWh solar batteries is enough to sufficiently power a house until solar production resumes or grid power is restored.

Can I Install My Own Solar Battery System?

Installing a solar battery system is subject to strict regulations to ensure safety and compliance. The Clean Energy Council (CEC) mandates that only accredited professionals can install battery energy storage systems. ​

Attempting a DIY installation without proper accreditation can lead to significant safety hazards and may violate local laws.

Which Type of Battery Is Best for Solar?

Lithium iron phosphate (LFP) batteries are widely considered the best solar battery. They’re safer, more stable, last longer, and perform better in high temperatures.

What is the best solar inverter to recommend to your customers? Let’s break down the features that make an inverter truly “the best”.

How Solar Inverters Work

You know how a solar inverter works, but explaining that to customers can be challenging! 

Try this:

Here’s a more technical explanation if they’re interested.

1. Solar Panels Capture Sunlight: When the sun shines on solar panels, the photovoltaic (PV) cells absorb the sunlight, exciting electrons and generating direct current (DC) electricity. 
2. The Inverter Receives DC Power: The raw DC electricity from the panels can’t be used directly in most homes or businesses, which run on alternating current (AC) electricity. The solar inverter receives this DC power and prepares it for conversion.
3. MPPT Technology Optimises Energy Production: The inverter uses Maximum Power Point Tracking (MPPT) technology to adjust the panels in changing sunlight conditions (shade, cloud cover, and temperature changes) to extract the maximum possible energy.
4. DC Power Converts to AC Power: Inside the inverter, the DC electricity switches rapidly back and forth, creating an alternating current (AC) waveform that matches the electricity used in homes and businesses. 
5. Grid Synchronisation and Safety Features Activate: If the system connects to the electricity grid, the inverter synchronises the converted AC power with the grid’s voltage and frequency. Anti-islanding protection automatically shuts off power if the grid goes down, preventing unsafe backfeeding into power lines during outages.
6. Power is Used or Sent to the Grid/Battery: The converted AC power flows into the home or business, powering appliances, lighting, and other electrical devices. Excess energy can be exported to the grid for credits (if grid-tied) or stored in a battery for later use (if part of a hybrid or off-grid system).

Importance of Solar Inverters for Solar Panels

A solar inverter 

• Converts Energy for Use. The inverter transforms raw DC power from solar panels into functional AC power for everyday use.
• Optimises Solar System Efficiency. A high-quality inverter maximises power output, improving energy efficiency and system performance.
• Monitors System Performance. Many modern inverters have monitoring features that track energy production, efficiency, and potential system issues.
• Enables Grid Connection. If a system connects to the grid, the inverter ensures that the electricity matches grid standards for seamless integration.
• Supports Battery Storage. In hybrid systems, inverters manage energy flow between solar panels, batteries, and the grid.

What Makes a Solar Inverter the Best? Key Features to Look For

Safety

A solar inverter should protect the solar power system, the home or business, and the people who depend on its electricity. Safety features prevent electrical hazards, extend the inverter’s lifespan, and comply with Australian electrical and grid standards. 

The best solar inverter should have the following safety features. 

• Arc Fault Protection: Detects and stops dangerous electrical arcs caused by faulty wiring, aging components, and loose connections, reducing the risk of fires.
• Cooling Systems: Heat sinks (metal components that absorb and dissipate heat) and passive cooling (which relies on natural airflow) prevent inverters from overheating and failing. 
• Surge Protection: Absorbs sudden voltage spikes caused by lightning or grid fluctuations, shielding the inverter from damage.
• Anti-Islanding Protection: Prevents the solar system from sending power back to the grid during a blackout, protecting utility workers and complying with regulations.
• Ground Fault Detection: Monitors the electrical circuit for leaks (where electricity unintentionally flows to the ground) and automatically shuts down the system to prevent electric shocks and fires.
• Rapid Shutdown Function: Quickly shuts down the system in an emergency, protecting installers and emergency responders from electrical hazards.

Reliability

A reliable solar inverter will produce consistent energy for many years, be less likely to break down, and be cheaper to maintain.

For an inverter to be considered reliable, it must have

• High-Efficiency Ratings. These translate to maximum energy conversion, reduced losses, and the delivery of more usable power from solar panels.
• Proven Durability. A quality inverter should have an IP65+ rating for weather protection, heat-resistant components, and robust build quality to withstand extreme temperatures, humidity, and dust.
• Consistent Grid Stability. To smoothly manage voltage fluctuations, grid instability, and load changes for stable operation, even during peak demand periods.
• A Long Warranty. A strong manufacturer-backed warranty of at least 10 years reflects confidence in the product’s longevity.
• Comprehensive Customer Support. Local technical support and service availability for warranty claims, installation queries, and performance issues mean installers and customers get fast, effective solutions when needed.
• A Proven Track Record. Trusted brands will have a history of positive user feedback.

Affordability and Value

When recommending an inverter, balance upfront cost with performance and durability so your customers get the best return on their investment. A well-priced inverter that performs dependably for years is a far better investment than a budget option that fails prematurely or needs frequent servicing! 

Here’s what to consider when evaluating affordability and value.

• Cost vs. Performance: While a lower-cost inverter may save money upfront, it could lead to higher maintenance costs or early replacement. Investing in a reliable, efficient model often yields greater savings over time.
• Warranty Coverage: A longer, manufacturer-backed warranty adds value by protecting against costly repairs or replacements.
• Efficiency and Energy Savings: A high-efficiency inverter converts more solar energy into usable electricity, reducing waste and maximising energy bill savings.
• Built-in Features: Some inverters come with advanced monitoring, surge protection, and battery compatibility, which provide added benefits without extra costs.
• Rebates and Incentives: Certain reputable inverters may be eligible for government rebates or incentives, making them more affordable.

Compatibility

A solar inverter must integrate with the rest of the solar power system for optimal performance. Choosing the wrong inverter can lead to inefficiencies, limited functionality, and even system failures.

An inverter should work well with

• Solar Panel Capacity and Voltage Range. The inverter must match the solar panels’ total power output and voltage to avoid energy losses and system inefficiencies.
• Battery Storage Systems. If the system includes (or may later include) a solar battery, a hybrid inverter will smoothly manage energy between solar panels, batteries, and the grid.
• Grid Requirements and Regulations. A compliant inverter must meet Australian grid standards, including voltage, frequency, and safety requirements for seamless grid connection and feed-in tariff eligibility.
• Monitoring and Smart Features. Many inverters integrate with Wi-Fi monitoring platforms, allowing customers and installers to track performance, detect issues, and optimise energy use.
• Backup Power and Off-Grid Systems. Some inverters can support off-grid or backup power functionality to keep essential appliances running during power outages.

Ease of Use and Monitoring

The best inverters should be easy for installers to install and easy for customers to operate. That way, everybody wins!

What makes an inverter easy to use and monitor?

• Simple Installation and Setup: Clear wiring terminals, straightforward mounting options, and an intuitive interface make the installation process quicker and reduce the risk of errors.
• Real-Time Energy Monitoring: Wi-Fi or Bluetooth connectivity lets users track energy production, consumption, and system health via a mobile app or web portal.
• Automated Alerts and Diagnostics: Smart inverters can detect faults, send automatic alerts, and give troubleshooting insights, helping installers and users resolve issues quickly before they impact performance.
• User-Friendly Display: Customers can check their system’s status at a glance on a built-in LCD or LED screen displaying performance metrics.
• Remote Access and Smart Integration: Some advanced inverters integrate with smart home systems, battery storage, and third-party monitoring platforms, giving users more control over their energy usage.

Comparing Solar Inverter Types: Which Is Best for Your Customers?

String Inverters

A string inverter is the most common type of solar inverter used in residential and small commercial solar systems. It connects multiple solar panels in a series (or “string”), converting the combined DC electricity from all the panels into usable AC power for a home or business.

Pros

✔ Cost-Effective: More affordable than microinverters or hybrid systems.
✔ Proven Technology: Widely used and trusted in the solar industry.
✔ Easier Installation and Maintenance: Since there’s only one inverter, servicing is simpler than troubleshooting multiple microinverters.
✔ Good for Unshaded Roofs: Works efficiently when all panels receive consistent sunlight throughout the day.

Cons

✖ Performance Dependency: Since all panels in a string are connected to one inverter, their performance is linked. If one panel is shaded, dirty, or underperforming, it reduces the efficiency of the entire string.

✖ Limited Design Flexibility: Panels must be installed at the same angle and orientation for best performance.
✖ No Panel-Level Monitoring: Unlike microinverters, string inverters don’t allow for individual panel performance tracking.  

Microinverters

Unlike string inverters, which manage multiple solar panels at once, microinverters are installed on each individual panel. This means every panel operates independently, converting its own DC electricity into AC power right at the source.

Pros

✔ Maximised Energy Production: Each panel performs independently, so shading or dirt on one panel doesn’t reduce the output of the others.
✔ Greater Design Flexibility: Panels can be installed at different angles and orientations on complex roof layouts or areas with partial shading without impacting system performance.
✔ Panel-Level Monitoring: Users can track individual panel performance, making detecting and fixing issues easier.
✔ Increased Safety: Converts DC to AC at the panel level, reducing the risk of high-voltage DC hazards.

Cons

✖ Higher Cost: More expensive upfront than string inverters due to needing multiple units.
✖ More Complex Installation: Each panel requires its own inverter, increasing installation time.
✖ Difficult Maintenance: If a microinverter fails, troubleshooting and repairs may be more time-consuming since each inverter is mounted on the roof.

Hybrid Inverters

A hybrid inverter does everything a standard solar inverter does—converting DC electricity from solar panels into AC power—but with one big advantage: it can also manage battery storage. Homeowners or business owners can store excess solar energy in a battery instead of sending it to the grid.

Pros

✔ Battery-Ready: Easily integrates with solar batteries for energy storage and backup power.
✔ Greater Energy Independence: Reduces reliance on the grid by storing excess solar power for later use, like at night or during blackouts

✔ Optimised Energy Management: Smart software helps manage energy flow between solar panels, batteries, and the grid for maximum efficiency.
✔ Future-Proof Investment: Allows for easy upgrades later if a battery isn’t installed right away.

Cons

✖ Higher Upfront Cost: More expensive than traditional string inverters due to added battery management features.
✖ System Configuration Required: While hybrid inverters are battery-ready, they can require custom settings and programming from a professional installer. 

✖ May Require a Compatible Battery: Some hybrid inverters only work with specific battery brands or types, limiting flexibility.

Central Inverters

Central inverters work similarly to string inverters but on a much larger scale. Instead of handling a few solar panels, they manage power from hundreds or even thousands of panels simultaneously. These inverters are typically used in large commercial and utility-scale solar farms, where multiple panel strings feed into a single, high-capacity inverter.

Pros

✔ High Efficiency for Large Systems: Optimised for processing energy from hundreds or thousands of solar panels.
✔ Lower Cost Per kW: More economical for large installations compared to using multiple smaller inverters.
✔ Simplified Maintenance: With a single, centralised unit, servicing and troubleshooting can be more straightforward than maintaining many smaller inverters.

<Cons

✖ Performance Dependency: Since many panels feed into one unit, an issue in part of the system can reduce overall efficiency.
✖ Higher Risk of Downtime: If the central inverter fails, the entire system stops producing power until repairs are made.

3-Phase Inverters

A 3-phase inverter is designed for properties with a 3-phase power supply, such as large homes, businesses, and industrial sites. Unlike standard single-phase inverters that send power through one electrical phase, 3-phase inverters distribute electricity evenly across three phases, making them ideal for handling higher energy loads.

Pros

✔ Ideal for High Power Demand: Supports larger properties with high energy needs, a 3-phase power supply, and inverter capacities exceeding 5kW.

✔ More Efficient Power Distribution: Spreads energy evenly across three phases, reducing voltage fluctuations and improving stability.
✔ Better Grid Compatibility: Works perfectly with 3-phase electrical systems, preventing overloads and improving performance.
✔ Supports Larger Solar Arrays: Can handle higher solar panel capacities for large installations.

Cons

✖ Higher Upfront Cost: More expensive than single-phase inverters due to their increased capacity and advanced functionality.
✖ May Require Grid Approval: Some locations have specific regulations for connecting 3-phase inverters to the power grid.

What is a solar inverter, and how does it work? Keep reading!

What is a Solar Inverter and How Does It Work?

A solar inverter takes the energy solar panels collect from the sun and turns it into electricity you can use at home. 

1. Solar Panels Capture Sunlight. The solar panels installed on your roof or on ground-mounted frames soak up sunlight and convert it into DC electricity (direct current). But there’s a slight problem—your home appliances can’t use this electricity!
2. The Inverter Steps In. The solar inverter takes that DC electricity and converts it into AC electricity (alternating current), which is the type of power your home runs on. It does this by rapidly switching the direction of the current using electronic circuits and components like transistors and capacitors. This process mimics the natural oscillation of AC power, making it compatible with your home’s electrical system. Your solar inverter will be installed near the main switchboard of your home, either on a shaded and well-ventilated exterior wall or inside a garage to protect it from extreme weather. 
3. Electricity Flows to Your Home. Once converted, the AC electricity flows to your power outlets for lights, appliances, and anything else that needs power.
4. Extra Energy Is Redirected or Stored. If your solar panels produce more energy than your home uses, the extra electricity can either go back into the grid, which may earn you credits on your power bill (depending on your energy provider), or be stored in a solar battery (if you have one), so you can use it later when the sun isn’t shining.
5. The Inverter Monitors Solar Output. A good solar inverter should also monitor how much electricity your panels generate and how much your home consumes using built-in sensors and software. This data is usually accessible via a display screen or a mobile app.
6. The Inverter Keeps the Solar System Running Safely. If there’s a fault—like an electrical surge, overheating, or a wiring issue—the inverter has protective circuits that detect the problem and automatically shut down the system.

Types of Solar Inverters

String Inverters

A string inverter is the most common type of solar inverter used in home solar systems. It connects multiple solar panels in a series (or “string”), meaning all panels feed their electricity into a single inverter.

Since all panels connect in a single string, performance depends on the weakest panel. If one panel is shaded or dirty, it can reduce the output of the entire string. So string inverters are ideal for homes and small to medium-sized businesses with uniform conditions: consistent sun exposure and simple roof layouts. 

What makes string inverters unique?

• Centralised Conversion: Instead of each panel having its own inverter, all the panels in a string send DC electricity to one central inverter for conversion.
• Cost-Effectiveness: Since there’s only one inverter for the entire system, string inverters are generally more affordable than other inverter types.
• Simple Installation and Maintenance: With fewer components, these inverters are easier to install and maintain.

Microinverters

A microinverter is a small inverter installed on the back of each solar panel instead of having one central inverter for the whole system. Each panel operates independently, converting DC electricity to AC directly at each panel.

Microinverters are ideal for homes and businesses with shading issues, as unaffected panels can continue operating at full capacity even if trees or nearby buildings shade other panels. They also work well for complex roof designs where panels face different directions or receive partial shading at various times of the day.

What makes microinverters unique?

• Panel-Level Optimisation: They maximise energy output from each panel, so shading or panel mismatches don’t reduce power.
• Improved Monitoring: Many microinverters feature panel-level monitoring so you can track the performance of each panel to detect issues, keep the system running efficiently, and prevent energy loss.
• Longer Lifespan: These inverters typically last longer than string inverters, often matching the 25-year lifespan of solar panels.

Power Optimisers

A power optimiser is a small device installed on the back of each solar panel that optimises the DC electricity before sending it to a central string inverter for conversion into AC power. Unlike microinverters, power optimisers do not convert DC to AC at the panel level. 

Power optimisers are best for residential and commercial solar systems that use string inverters and need improved performance for panels installed in partially shaded areas or at different angles. 

What makes power optimisers unique?

• Works with a String Inverter: Unlike microinverters, power optimisers don’t replace the main inverter but enhance its performance by improving DC output before conversion.
• More Affordable: Since conversion still happens at a central inverter, power optimisers cost less than installing individual microinverters on each panel.
• Better Monitoring and Fault Detection: Individual panel monitoring and quick troubleshooting are possible, but complete data access requires a compatible inverter.

Hybrid Inverters

A hybrid solar inverter does the work of a standard string inverter with the bonus of managing battery storage. Instead of sending excess solar energy to the grid, a hybrid inverter can store that energy in a battery for later use when the sun isn’t shining, reducing reliance on the grid and providing backup power during blackouts.

Hybrid inverters are ideal in areas with unstable grid supplies and for households wanting to maximise their solar energy usage. While they cost more upfront than standard inverters, they offer greater solar power flexibility and long-term electricity savings.

What makes hybrid inverters unique?

• Built-in Battery Management: Controls both solar energy and battery storage in one system.
• Smart Energy Use: Automatically switches between solar, battery, and grid power based on demand.
• Future Scalability: You can start with a basic solar system and add a battery later, making it easy to upgrade as your energy needs change.

3-Phase Inverters

A 3-phase inverter connects to a 3-phase power supply. Unlike standard single-phase inverters, which send all solar energy through one power line, a 3-phase inverter evenly distributes electricity across three power lines.

3-phase inverters are ideal for larger homes, commercial buildings, and industrial facilities that require higher power loads due to many occupants, heavy machinery, large air conditioning systems, and other high-energy equipment.

What makes 3-phase inverters unique?

• Even Power Distribution: Provides a more balanced and efficient energy flow and reduces the risk of power drops when multiple high-energy appliances run simultaneously.
• Grid Stability: Helps maintain a more stable voltage, reducing strain on the electricity grid and minimising the risk of overvoltage issues that can occur with high solar output.

Why Safety and Reliability Are Critical in Solar Inverters

A solar inverter constantly converts energy, manages power flow, and handles high-voltage electricity. If your inverter is not well-protected and reliable, your system could experience performance issues, electrical faults, and safety risks.

Look for the following safety features in advanced, top-of-the-range inverters.

• Arc Fault Circuit Interrupter (AFCI): Detects and shuts down dangerous electrical arcs, which can cause fires due to faulty wiring, aging components, or loose connections. 
• Natural Cooling Systems: Overheating is a major cause of inverter failures. High-quality inverters use heat sinks—metal components that absorb and dissipate heat without fans or moving parts—and passive cooling, which relies on natural airflow. This design reduces operating noise and system wear. 
• Surge Protection: Shields the inverter from sudden voltage spikes caused by lightning strikes or grid fluctuations.
• Ground Fault Detection: Identifies leaks in the electrical circuit and shuts the system down to prevent electric shocks or fires.
• IP-Rated Enclosures: A weatherproof casing rated IP65 or higher protects the system from dust, rain, and extreme temperatures to extend its lifespan. 

Choosing the Right Solar Inverter for Your Solar Panel System

Picking the right solar inverter is just as important as choosing your solar panels. The inverter controls how efficiently your system runs, how long it lasts, and how well it integrates with your home’s power needs. 

Here’s what to consider.

1. Compatibility

Choose an inverter that matches your solar panel capacity to avoid energy loss.

If you plan to add battery storage, choose a hybrid inverter to handle both solar and battery power. 

If your home uses 3-phase power, choose a 3-phase inverter for even energy distribution, provided it meets local grid regulations. 

2. Performance

Consider efficiency ratings. Higher efficiency means less energy wasted during conversion.

If your roof has shading or different panel orientations, microinverters or power optimisers can prevent one shaded panel from reducing the entire system’s output.

3. Safety

Make sure that the inverter has safety features like an AFCI (Arc-Fault Circuit Interrupter), surge protection, and ground fault detection.

4. Durability

Look for an inverter with strong weather protection (IP65 or higher) if it will be installed outdoors.

Also, look for passive cooling systems (with heat sinks instead of fans), as these tend to last longer and operate quietly.

Check the warranty. A quality inverter should have at least a 5-year warranty.

5. The Advice of a Reputable Solar Company

The best way to find the right inverter for your needs is to speak with a trusted solar provider. 

Ask them:

• What type of inverter is best for my home and energy usage?
• Does this inverter work with battery storage if I want to add one later?
• What safety features does it have?
• What warranty and support options are available?

A provider that knows their stuff—like iStore!—will be able to answer these questions and guide you to the right inverter.

A microinverter is a small inverter installed on each solar panel that converts DC electricity to AC electricity directly at each panel. Unlike string inverters, microinverters allow solar panels to operate independently, improving efficiency and performance, especially in shaded or multi-angle installations.

How Reliable Are Solar Inverters?

Solar inverters are highly reliable when properly installed, monitored, and maintained. Most quality inverters last 10–15 years, with some premium models lasting even longer. 

Factors like cooling systems, weather resistance, and brand reputation affect durability and the inverter’s lifespan.

Is It Safe To Sleep Near a Solar Inverter?

There is no proven evidence that exposure to electric and magnetic fields from solar inverters causes health effects, so sleeping near a solar inverter is generally considered safe. Modern inverters are designed to meet strict safety standards and emit low levels of electromagnetic fields (EMFs). 

However, installing inverters in well-ventilated areas away from living spaces is advisable to minimise potential noise and heat. Proper installation and adherence to manufacturer guidelines are essential for safety.

If energy costs are eating into your profits, a 3-phase solar inverter might be the thing to get your business out of the red. This setup can handle heavier loads, perfect for businesses with round-the-clock operations or power-hungry equipment. 

Keep reading as we explain what a 3-phase solar inverter is, why it matters for small enterprises, and how iStore’s competitively priced, high-quality models can help you save on bills and meet sustainability targets. If you’re ready to take control of your overheads and go green, keep reading to see how a 3-phase solution can benefit your bottom line.

What Is a 3-Phase Solar Inverter and How Does It Work?

So, how does a 3-phase solar inverter work? It’s not that different from a single-phase inverter. It takes the direct current (DC) from your solar panels and converts it into alternating current (AC). It then spreads that AC power over “three” phases. 

This setup is common in commercial buildings or larger homes because it can handle much heavier electrical loads. If you have multiple machines, computers, or appliances running at once, you’ll benefit from the balanced, stable supply a 3-phase solar power inverter provides.

Key Differences Between Single-Phase and 3-Phase Solar Inverters

Single-phase inverters work well for standard homes with a single-phase power supply. They use one active (live) wire to deliver electricity. A 3-phase inverter solar model, on the other hand, has three active wires. 

This means

1. A typical single-phase system has one active wire and one neutral (plus earth). It’s common in smaller homes that don’t require large power loads.
2. A 3-phase system has three active wires (plus neutral and earth), delivering power in three alternating waves. This allows for higher loads and a more balanced distribution of electricity.
3. The 3-phase option typically costs more than a single-phase model. If your property already has 3-phase power, though, you can handle a bigger solar system and get greater energy offsets.

For a small business, investing in a 3-phase hybrid solar inverter is the smart route if you plan to expand your solar array or add battery storage later. The ability to easily handle bigger loads can give you peace of mind as your business grows.

Advantages of 3-Phase Inverters

A 3-phase solar inverter can do more than just split your solar power into three parts.

• Higher Capacity. You can install larger solar systems without risking an overload on any single phase.
• Grid Friendliness. Three-phase setups often reduce strain on the local grid. Utilities sometimes prefer 3-phase connections for higher-capacity solar projects.
• Greater Efficiency. By balancing loads across three phases, you typically see smoother performance and potentially better returns on your solar investment.

Because they handle more power, 3-phase solar inverters are usually recommended for businesses or homes with three-phase lines and solar systems larger than 5kW.

Why Small Businesses Need a 3-Phase Solar Inverter

1. Energy Efficiency. By spreading electrical loads evenly, you reduce the chance of any single phase getting overloaded. That can lead to lower operating costs if you use a lot of power throughout the day.
2. Business Continuity. Keeping operations smooth is critical for small businesses. A reliable 3-phase system ensures stable power for essential equipment.
3. Future-Proofing. If you plan to expand your solar capacity, a 3-phase inverter for solar panels can handle the extra load. You won’t need to replace the inverter later!
4. Eco-Friendly Approach. Going green can be good PR. Customers often prefer companies that take real steps toward sustainability. It also helps you cut carbon emissions and meet any sustainability targets you might have.

Understanding the Cost and Return on Investment

It’s true that 3-phase solar inverters usually cost more than single-phase models. For some standard systems, the difference between a single-phase and a 3-phase model might hover around a few hundred dollars, while for others—especially higher-capacity or premium brands—it could be higher.

For many small businesses, the long-term return on investment can be higher with a 3-phase setup. You can install a bigger solar array and offset more of your energy use, which means larger savings on those monthly bills. Over time, the difference in upfront cost may be small compared to what you gain in energy savings.
