Hi Everyone - I am new to the forum but have found the posts extremely helpful as I learn more about the topics here. I currently have a grid tied 7KW PV system and just experienced a nice 48 hour power outage due to a bad storm. I would like to add battery backup to run the bare essentials (well pump, freezer, refrigerator, gas furnace, some lights). I'm calculating I would need ~6kWh for these essentials. I am hoping to do a minimal setup (~1 day of power) now and potentially expand my battery capacity in the future.
I see hybrid/all-in-one split phase AC coupled inverters that can handle the GT PV and batteries but I'm a little confused about what I would need as a minimum battery capacity given my PV set up.
Apologies if this is a trivial question I haven't been able to find a good answer in my searches so far.
