What size inverter do I need for 100Ah battery?

So, with this information at hand, a common 100Ah-150Ah lithium battery of this type can deliver enough energy to operate a maximum of a 1000w inverter.

What size solar panel do I need to keep a 100Ah battery topped up?

In general, a 100Ah deep-cycle lead-acid battery would require 180 watts of solar panel to fully recharge from 50% Depth of Discharge (DOD) assuming 4.2 peak-sun-hours per day.

“AH” stands for “amp hours”, and simply put, 100ah means that a battery can deliver 1 amp of current at the rated voltage (12V in this case) for 100 hours. Or, alternatively, 2 amps for 50 hours, or 4 amps for 25 hours or 100 amps for 1 hour and so on. A 100ah battery will provide 1 amp X 12 Volts = 12 Watts for 100 hours.

### How many watts is a 100Ah battery?

A 100ah battery will provide 1 amp X 12 Volts = 12 Watts for 100 hours. On the high end, 100 amps X 12V = 1200 Watts for one hour. Important: In order to maintain the lifespan, 12V batteries like these should never be drained past 50% charge .
