Day 1 DC Principle 101 class.

So all 4 in series and you have 24 volts @ 225 AH with 5400 watt hour capacity.
2 in series, in parallel with 2 in series (aka 2 x 2) is 12 volts @ 450 AH with 5400 wh capacity.
All 4 in parallel is 6 volts @ 900 AH and 5400 wh capacity.

Hello
I have an inverter which is V24. I also have 4 x 6v T105 trojan batteries. These batteries are 225 Ah each. I have to series stringing the batteries so that I achieve 24v for the inverter.

My question is, considering my method of combining the batteries will I only have 225Ah as an available capacity for my solar system? Or is it 225AH x 4= 900 Ah will be the available storage capacity for my solar system? if not then how does this work. How can I fully utilize the capacity of the 4 batteries

When wiring batteries in series the voltage adds up but the Ah stays the same.

Similar when wiring batteries in parallel the Ah adds up and the voltage stays the same.

Your 4 x 6v 225Ah batteries when wired in series make up a 24v 225Ah system which has a max rating of 24v x 225Ah = 5400 watt hours. You should be able to safely use 20 - 25% of that or ~ 1200 watt hours daily.

Wiring those batteries in series to make a 24volt system is IMO fully utilizing their capacity.
