Hi Everyone!
My question may or may not be silly, unsure if I am simply overthinking it or not!
So, we have a 9KW solar system, 18x 500w panels. 2 Charge controllers, 1 Inverter and 16 x 300ah LiFePo4 cells wired together to make a 48v battery pack. When the batteries are full, they are at 56.8volts.
I have calculated the battery storage capacity as 300ah x 56.8v = 17,040 watts.
The battery pack is suppling power to a cabin, which is drawing AC and uses 220volts.
So my question is, if my cabin is using 220v, but my battery pack is 56.8v does this mean that a 4watt hour light is still drawing 4 watts per hour? Or does this figure change because it is being operated on a 220v system? And is my battery storage figure of 17,040 watts accurate, or does that also change?
Please help! I hope this was written clearly enough to understand.
Thanks for any help you can provide.
