FranklinWH Battery 

Introducing the FranklinWH battery. The Franklin battery, much like the Telsa Powerwalls, are another battery backup we use that offers reliable power to manage your energy consumption by powering your home at night and using it as a backup for brownouts & blackouts if the grid goes down. This system integrates solar, grid, battery storage, and the ability to integrate a generator to maximize grid resiliency and optimize your energy efficiency.  

Franklin batteries have a 13.6kWh storage battery and can be expanded to 204kWh  

Apart from Tesla Powerwalls the FranklinWH batteries are a great solution for those who want to integrate a generator into their systems as additional security or who want to go completely off-grid.
