Can this be used with a standby battery instead of a gas-powered generator? We had this installed in our cabin when it was built in 2013 but did not add a generator yet. Batteries are starting to look like a better option for our needs.

Thanks for your question, James! This advanced load center is only intended to be used in conjunction with a home standby generator. To learn more about our battery storage solution, see here: https://www.generac.com/solar-battery-storage/
