Solar charged to 99% state of charge at end of 1st day.
Solar charged to 96% SOC at end of 2nd day.
So it looks like we will need to run the genny once every 4 or 5 days for an hour or two. Or we might add another 400 watts of solar.
What is missing is how much battery AH you currently have and how many watts solar you currently have. Since LFP can be used down to 5% SOC, I would think you could easily go for a couple weeks, with current setup and usage.

My signature shows the "missing" info.
And, yes I can go more than a few days, but it's nice to be "topped off", just in case.

"1200 watts solar, 3kw inverter/charger, LiFePo 618 AH batteries" and still thinking of adding another 400 watts of solar. Wow that is some expense just for running a refrigerator.

Just "gravy". I think we could get by with half of what we have. But more panels is sort of like more horsepower-you don't need it but it's nice to have if you want it.
