How to Choose the Right Battery for Your Project
Battery current is a main driver of how much runtime you will get out of a battery. Battery current is expressed in Amp-Hours (Ah). Amp hours is the amount of current sourced from the battery that would cause it to fully discharge in 1 hour. For example, if you have a 5Ah battery and a load that draws 2.5A, your battery will run for 2 hours.

How Much Battery Do You Really Need?
Chris Warren Post author August 12, 2018 at 23:47. Hi Richard, if you are using a 12 volt battery then you''ll want your battery bank wired in parallel. Wiring batteries in series adds the voltages, so two 12 volt batteries in series will be 24 volts, three would be 36 volts, etc. When wiring batteries in parallel, the voltage will stay the same but the current will be added.
How Many Batteries For a 3000 Watt Inverter?
If you opt for a 24V battery instead the battery bank size is reduced: 3000 / 24 = 125. The same inverter will run at full power for an hour so on a 125ah 24V battery. Many inverters support 24V batteries, and while these batteries cost more you can get by with a smaller capacity. A 150ah 24V battery is the minimum required to power the inverter.
