A brief rundown on what I'd like to do. This may seem silly, but baby steps for me here. I want to take one of my 18.2cf refrigerators off the grid. I've calculated it pulling approximately 600W 5.22A 115V.
I need to figure what amp hour battery size to cover the refrigerator for approximately 15 hours. I have completed my two solar panels each at 24V with 3.5A. More than likely will parallel them to give me 7A (in full direct sun of course) 3-4A more like it I suspect.
Only running the battery down to 50% of it's full capacity doubles the amp hours needed. With a 100Ah rated battery pulling 5.22A you'd get 19.16Ah and then split that by 50% so as not to run the battery completely down gives me 9.58Ah with the 100Ah rated battery. Am I correct? Anything else I have overlooked? Thanks All!
