currently have 4.4 kw sytem on flat garage roof in Denver area. 1 string, 12 panels, 6 microinverters, runing into combiner through disconnect into my house breker panel.
we have been talking lately about adding battery backup. i would like to keep battery backup related items in the garage.
now as i understand, once the grid is down, my solar system shuts off to prevent feeding power to the grid and electocuting potential workers.
now with batteries, if they keep feeding power to my breaker box even during blackout, what prevents that power going to the grid?
also, i am looking for suggestion on how to add batteries to my system. i have not have much luck online finding something that works with microinverters. any idea as how to retrofit batteries to my existing system? i am attaching one line and roof plan for my system for reference.
if adding to existing sytem proves difficult, i am open to adding 2nd string. i did pre-wire for 2nd string and i have wires for it running from garage roof to combiner panel, they are just not used right now. with new string, i assume it should be easier to add battery backup. i am not set on microinverters so there should be more options? i see a lot of different approaches, and prices for batteries and inverters vary quite a bit. what would be a good value package? i dont really need anythig fancy, we dont get blackouts much, i mostly need it for my computers and animals during winter months. if i was to do 2nd string i would probably go for same size as my 1st string, or smaller, 3-4kw maybe.
any help appreciated
