10 computers, 1 refrigerator, and 4 light bulb rooms,

will you think about to use hybrid system? that means solar power and AC/DC charger two ways to charge your battery bank,

see your total load is around 3-4kw, right? you need at least a 5kw pure sine wave inverter, and solar panel array is 5kw, AC/DC charger is 4~5kw, when you have the main power, you can charge your battery bank with the AC/DC, and in the daytime, your solar panel will also charge your battery bank.

pls check the attached excel FYI.

i'm sorry, i saw your post is "don't have electricity", what's that means? the main power is not good or even you don't have electricity at all?
