Three-phase grid connection

Designed for three-phase properties

Each inverter supplies energy through a three-phase grid connection, supporting appropriately designed residential and light-commercial energy systems.

01
Three output choices

10kW, 15kW and 25kW models

Select an inverter output suited to the property’s electrical capacity, solar-array design, expected consumption and applicable network requirements.

02
Battery-ready hybrid technology

Compatible storage within one energy system

Connect compatible iStore battery storage from 5-60kWh to capture surplus solar generation and make stored energy available for later household use.

03

Which model is right for your property? An accredited installer must assess the electricity connection, switchboard, network requirements, solar-array capacity, battery configuration and intended operating requirements.

High-capacity solar input

More solar capacity.
More opportunity across the day.

Each inverter supports recommended PV capacity equal to up to 250% of its rated output, giving an accredited installer greater flexibility when designing higher-capacity solar systems.

Two independent MPPT trackers and up to four PV inputs can accommodate separate solar strings, roof orientations and differing operating conditions while remaining within the inverter’s electrical limits.

Two independent MPPT trackers

Each tracker manages its connected solar strings independently within the inverter’s specified voltage and current limits.

01

Up to four PV string inputs

Two string inputs per MPPT provide greater flexibility for professionally designed solar arrays.

02

Greater generation opportunity

Additional panel capacity can support stronger generation during mornings, afternoons and periods of lower solar irradiance.

Input current per MPPT Up to 30A

The maximum input current is 30A per MPPT when using two strings and 20A when using a single string. All connected strings must remain within the inverter’s voltage, current and system-design limits.

Understanding PV capacity: Connecting additional panel capacity does not increase the inverter’s rated AC output. Final PV capacity depends on string design, connected battery storage, inverter limits, network requirements and applicable Australian standards.

Frequently asked questions

Three-phase
hybrid inverter
questions.

Understand model selection, solar capacity, battery storage, monitoring and system design before planning your three-phase energy system.

✣
Professional system design

Every property is different.

An accredited installer can confirm your electricity connection, appropriate inverter model and final solar-array configuration.

▦ Review specifications
01 Which inverter model is right for my property?

Model selection depends on your electricity connection, proposed solar-array capacity, battery-storage requirements, network export limits and expected energy demand. An accredited installer can assess these requirements and recommend the appropriate 10kW, 15kW or 25kW model.

02 How much solar-panel capacity can each model support?

The recommended maximum PV capacity is 25kWp for the 10kW model, 37.5kWp for the 15kW model and 62.5kWp for the 25kW model. Final panel capacity depends on string design, electrical limits, site conditions and applicable network requirements.

03 What does up to 250% PV capacity mean?

It means the recommended maximum solar-array capacity can be up to 250% of the inverter’s rated AC output. A properly designed larger array may improve energy generation during mornings, afternoons and periods of lower solar irradiance.

04 Can the inverter connect to an iStore battery?

Yes. The range is designed for compatible iStore Smart String ESS battery storage from 5-60kWh. Battery configuration, usable capacity and charge performance depend on the selected modules and professionally designed system.

05 Can multiple inverters operate together?

Up to three compatible inverters can be configured in parallel with a compatible Smart String energy-storage system. Final system capacity and configuration remain subject to the current product documentation, network connection and professional system design.

06 Can I monitor solar and battery performance remotely?

Yes. Integrated WLAN supports connection to the compatible iStoreHome monitoring platform. Available information can include solar generation, property consumption, battery activity, operating status and system events when the required meters and compatible equipment are installed.

07 Can the inverter be installed outdoors?

The inverter has an IP66-rated enclosure for protection against dust and water ingress. Installation location, clearances, ventilation and environmental exposure must still comply with the current installation documentation and applicable electrical requirements.

08 What warranty applies to the inverter?

The inverter is supported by a 10-year parts and labour warranty, plus a complimentary two-year parts-only extension subject to the applicable warranty terms, product eligibility and installation requirements.
