FranklinWH
A complete home energy management and storage system that brings solar, battery, grid, generator and EV power together. The FranklinWH aPower battery and aGate energy management centre help you use more of your clean energy and keep essential power ready when the grid goes down.
A connected FranklinWH system
FranklinWH combines the aPower battery with the aGate energy management centre to coordinate your home’s solar, battery, grid, generator and EV power. It is designed as an open energy ecosystem, helping homeowners optimise supply, consumption and energy security from one system.
Its AC-coupled architecture makes FranklinWH a practical choice for existing solar homes. The system can work alongside an existing solar inverter, reducing the need to replace equipment when adding battery storage.
Through the FranklinWH app, homeowners can monitor energy status, review estimated savings and tailor settings for how power is used across their home. Intelligent controls prioritise self-generated energy and can support whole-home backup during an outage.
What Makes the aPower Different
12-year warranty
The longest standard battery warranty available in Australia — 12 years or 60 MWh throughput. Two years longer than most competitors, backed by a global manufacturer.
AC-coupled flexibility
Works with any existing solar inverter brand. Add the aPower to your current system without replacing your inverter — a significant cost saving for retrofit installs.
Whole-home backup
Seamless switchover to island mode when the grid goes down. The aGate energy management hub coordinates all power sources automatically — no manual intervention needed.
Open energy ecosystem
The FranklinWH system integrates solar, battery, grid, generator and EV power into one intelligent platform. Add or change components over time without starting from scratch.
Fanless, silent operation
Natural convection cooling means no fan, no moving parts, and virtually silent operation — suitable for installation near living areas, garages, or bedrooms.
6-layer battery protection
Six layers of protection including intelligent thermal management, electrical safety, structural protection, and battery integrity management — engineered for extreme Australian conditions.
