Technical Specifications

Powerful 12kW Solar Backup

With 12kW of inverter capacity, this system is designed for customers who require more power than typical 5kW or 8kW residential systems can provide.

The system can support a wide range of household and business loads, while the 10.24kWh battery stores energy generated from solar for use during the evening, power outages or periods when solar generation is unavailable.

Actual backup duration will depend on the connected load, battery settings, inverter efficiency, solar generation and operating conditions.

Long-Life LiFePO₄ Battery

The included Lithium Valley 10.24kWh battery uses Lithium Iron Phosphate technology, providing a durable energy-storage solution with a rated life of up to 6000 cycles at 80% depth of discharge.

The integrated intelligent BMS helps monitor and protect the battery, while RS232, CAN and RS485 communication enables compatibility with supported inverter communication protocols.

With support for up to 15 batteries in parallel, the storage capacity can be expanded as your energy requirements grow.

Flexible Solar & Backup Operation

The Growatt inverter features dual MPPT tracking, allowing the system to efficiently manage solar generation from multiple PV strings. Generator support also provides an additional backup option where required.

The system is suitable for both solar energy storage and backup power, helping customers maximise available solar energy and reduce dependence on grid electricity.
