Whole-Home Energy Storage Built for Greater Independence
The FranklinWH aPower 2 is a high-capacity home battery designed to keep your household powered when the grid goes down while giving you greater control over how and when your home uses energy.
With 15 kWh of usable LFP battery capacity and 10 kW of continuous output, the aPower 2 is built to handle substantial household loads and provide dependable backup power for compatible home circuits and appliances. It can deliver up to 15 kW of peak power for 10 seconds, providing additional capability for equipment with demanding startup loads.
Designed around 120V/240V residential electrical systems, the aPower 2 integrates with the FranklinWH energy management ecosystem to coordinate battery storage with available solar generation, grid electricity, generators, and household energy use.
The system is also highly expandable. Multiple aPower 2 batteries can be combined as household energy requirements grow, allowing homeowners to increase storage capacity rather than replacing the original system.
Built with durable lithium iron phosphate (LFP) battery chemistry, the aPower 2 provides a long-life energy storage platform for homeowners looking for reliable backup power, greater energy resilience, and increased energy independence.
