I am having problems calculating the number of 12v 200ah lead Acid batteries I need for a 115,218wh load. I'm planning on running this on a 10kva 120v Inverter ... Please can anyone help me out on this one?
Thanks
What nominal input voltage on that inverter? 48V?
And is the 115,218Wh load presented as a constant load distributed over 24hours?
Assuming 48V battery bank you will need “on paper” 96 FLA 200Ah batteries for 24hrs. And that’s ~100A+ at 48VDC nominal input, ~40A 120VAC output
But they won’t be running on paper, and I’m wildhat guessing here. You don’t mention your region, the wattage of your solar array or hydro (wind?) generation (if any), or whether or not this is backup or daily cycling. You may need more batteries or less depending on the variables and SLA, FLA, or type/form of the individual batteries.
