Hi m I am new on solar, i purchased my first inverter the 6000XP , it is still in shipping.
I want to know how long does it take to charge a lifepo4 batteri 51.3V 100A when using the grid power only.
What is the equation i shold use to calculate that. I need to learn so i can calculate again when using solar and grid
Thanks

In the most basic form, it is - the number of Amp Hours you want to put into the battery divided by the number of Amps you are putting into the battery = hours to fill the battery.
Say you have drained 10amp hours and you charge at 1 amp. 10AH/1A = 10 hours.
or
You have drained 50AH and you charge at 10A. 50AH/10A = 5 hours.
With that being said though in reality it is generally a bit different.
If the batteries have a BMS they most likely will reduce charging amps as the batteries near 100% so might take a bit longer.
Inefficiencies in the system will make it take a bit longer.
Big thing to watch/check.
Double and triple check the maximum and recommended charge rates of the batteries and do not exceed that as a charge rate.
Hope that helps some,

Sometimes the easiest solution is the best solution.
Sometimes not.
