About This Product
The FranklinWH aPower 2 15kWh 10kW AC Coupled Battery is a residential energy storage unit designed to store electricity for household use, backup power, and solar energy management. Part of the FranklinWH home energy system, the aPower 2 combines battery storage with an integrated bidirectional inverter, providing 15 kWh of rated energy capacity and 10 kW of discharge power.
The battery operates on supported 120/240V and 120/208V single-phase electrical systems and is designed to work with the FranklinWH aGate energy management gateway. This arrangement allows stored energy to support selected household circuits or configured backup loads during utility outages, subject to system design and installation.
Its AC-coupled architecture makes it suitable for both new solar installations and compatible existing solar systems without requiring replacement of the existing solar inverter solely to add battery storage.
