More Storage, Greater Energy Independence
Make the most of every kilowatt-hour your solar panels generate.
By expanding your existing Indevolt battery system with an additional 4kWh of storage, you can capture more surplus electricity during the day and use it when you need it most.
Whether you're looking to increase your evening energy availability, reduce grid electricity consumption or take advantage of off-peak electricity tariffs, the PFA4000 provides the additional capacity to support your household's energy requirements.
Flexible Expansion with BatteryFlex Technology
Indevolt's innovative BatteryFlex technology makes expanding your energy storage system easier than ever.
Compatible battery modules with different storage capacities can be combined within the same system, allowing you to build an energy storage solution that grows alongside your needs.
Each battery operates independently to maximise available capacity, while automatic fault isolation helps maintain safe and reliable system performance.
Advanced Battery Technology
Built using durable LiFePO₄ battery chemistry, the PFA4000 is designed for long-term performance and everyday reliability.
With a manufacturer-rated lifespan of up to 10,000 charging cycles and intelligent safety features, it provides a dependable solution for households looking to maximise their investment in renewable energy.
Important Product Information
Please note: The Indevolt PFA4000 is an expansion battery designed to increase the storage capacity of a compatible Indevolt energy storage system.
It is not a standalone solar battery or inverter and must be connected to a compatible Indevolt main unit to operate.
Compatibility should be confirmed against the manufacturer's latest guidance before purchase. The main PowerFlex unit and any additional accessories are sold separately.
