Grid tied micro inverters adding a battery
I have an enphase solar system with iq7 micro inverters. I also have a 15KWh battery bank that I want to add as a back up and have the battery power the house at night when it isn''t producing solar. My main confusion is how to charge the batteries from solar when the grid is down. The envoy/iq system shuts down if the grid is down.
