Reprobate:
so on luminous india site, they stated that the 220ah 12v flooded batt will last about 4hrs on 500w load , and 29hrs on 100watt load.
am a lil confused, assume I connect the following, which will last longer?

A. 2x 12v 220ah batt to a 1.5kva 24v inverter to power a 500w load

B. 1 X 12v 220ah batt to a 1.5kva 24v inverter to power a 500w load.

Can you correct B above ( 1 x12 V ) cannot be connected to 24 V inverter . Read On…

I have used both controllers extensively below are my observations. Read On…
