House avg consumption 400 kWH / 3 month
5 kWH per day

1)Deep cycle battery

AGM batteries

To be safe side i need 10kWH battery power, per day (50% worst discharge) 4x batteries 12V 258Ah(24h rating), output 48V, AGM batteries $629 ($2516 total), expected lifetime 5 years (max 7) (With daily discharge cycle 50% - only 1000 cycles!!!, means 3 years)

50-80%(30% = 3kWH) will take 60Amps per 200 Ah battery, in my case 60V * 60A to 220V/16.36Amps.

Actually if i fit in 15A, it will take around 1 hour to reach 80% charge. Then around 2-3 hours on 40A current (need calculation, adsorption stage have non-linear current).

Example: Inverter 7.5A charge current / 360Wh, needs 13 hours.
