Oh, apologies for the battery size. I indicated earlier that I used a 65AH. It is a 35AH. I was going back and forth during the design and once I ran the calculations, realized the 30 watt panel wasn’t sufficient to properly charge the 65AH battery at the proper rate of c/5 to c/10. The 35AH gives 2 1/2 days backup while maintaining battery health (discharge to only 50%). So, theoretically it could go about 4 days without sun but that would be BAD for your battery…
