24v 8Kw or 48v 4Kw

[Andrewko]

I have an off grid solar setup that has been working fine until winter and more power tool usage has left me charging batteries of a gas generator. I have a 24v inverter from amazon and a 100amp renogy charge controller with 6 Lifepo4 12v 200ah batteries wired 3 series/3 parallel. Im thinking of getting two more batteries and either continuing with 24v and bumping it up to 800ah or buying a new 48v inverter and wiring the 8 batteries 4 series/2parallel. Which would provide more power?

Thank you,
AK

If I'm reading what you want to do correctly, your 800ah battery bank at 24v will = 19,200wh and your 400ah battery bank at 48v will also = 19,200wh.

8kw is twice as much power than 4kw.

Lets do some math. 8 batteries of 200ah at 12vDC: 8X200ahX12vDc=19,200wh
This is what they have though if you wired them in different ways either you voltage rises and ah stays the same or the ah increases and the voltage stays the same.

A batteries ah is a measurement of capacity.

Yes that’s correct and i do realize the math adds up to the same number, 19,200wh. I wanted to know if one was better than the other. For now im just going to add two more batteries and keep it as a 24v system.
