I am really new into this. I hope I phrased my question appropiately
Assuming I have 200 Ah / 6 volt battery rating, that would mean it could cover 1.2 kWh load.
And if I need to run my 400 kWh / 220 volt AC house monthly, will I need at least 400 of them?
Or the conversion from 6 volt DC to 220 volt AC require additional calculation?
