Hello, I'm a complete newb, please forgive my ignorance.
I'm trying to figure out how to calculate the wattage a battery bank can output. The Tesla and Enphase batteries all tell you what their output is so it's easy to understand how a solar installation matches up to the batteries you have. But I'm looking at stringing together 40 nickel iron cells to make a 48-volt battery.
If the batteries are hooked up to a 220 amp circuit at 48 volts then that's 10.56kW of power. If I have 40 of the 1200ah cells, does that mean I have 48,000ah total? And then 48,000ah/220a = ~218 hours of 10.56kW? That sounds like way too much!
So the discharge rate here has to do with the amps, but some batteries can't discharge as fast as others, so maybe you can't just hook up the battery to whatever amp circuit you want.
And there's probably something about AC versus DC I'm completely missing.
Here's a spec sheet on these kinds of batteries: https://ironedison.com/wp-content/uploads/2020/12/Iron_Edison-Nickel_Iron_TN_SPEC_Sheet.pdf
Any help is appreciated! Thanks.
