Wanted to take a few minutes to explain my back-up charging system that I use to keep my batteries charged. I got this great package from Lowe’s and have been very happy with it so far. I had to do a few minor mods and tossed the switch box that came with it. My Xantrax inverter automatically detects the generator, syncs the cycles and controls the charge for my 380 amp batteries.
The Guardian 8kw provides around 25 amps to feed my batteries on those days that give me little to no good sunshine for a couple of days. This only happens during rain storms or heavy snow falls. Typically last winter when the days were short and the sun was low in the sky we got buy just fine running the generator for 1 hr in the morning and then late in the afternoon for about 1 1/2 hrs. But on days with fair to moderate sunshine it just sits there looking good.
