Greetings & Welcome!
You’re getting the cart before the horse.
A) Figure out how much power you will use & double it.
B) Figure out the size of battery you’ll need for xx days, remembering there will be days of little or no solar power. Then double that because you shouldn’t run your battery(s) below 50%.
C) Now you’ll have xx ah of battery storage. Multiply the number of ah by at least 2, and preferably 3x to get the amout of solar you’ll need.
D) Then you can figure out the controller and other materials (fuses, wiring, etc. sizes).
E) Inverters are very inefficient, avoid them if at all possible.
Good Luck!
Cheers!
