June 6, 20188 yr I have an off grid cottage that I use once or twice a month. 12x255W Enersol panels (4 strings x3), 8x260 Omnipower Batteries and a Axpert 5kVA Inverter When I'm not there, should I switch off the AC Mains, or should I leave a fridge or similar running to keep up a little cycling of the batteries? The panels keep on feeding into the inverter&batteries in both scenarios.
June 6, 20188 yr Switch the fridge off - switch the inverter off. The SCC will continue to function and keep your batteries charged. The batteries do not need cycling to prolong their life.
June 6, 20188 yr Flip side. If the fridge must be on, I would put it on solar. Fridge gasses are stirred, batteries are giving some form of ROI etc.
June 7, 20188 yr Author Thanks Guys! Wasn't aware that I could switch off the Axpert as well. Are you saying that even when switched off it still monitors the batteries and keeps them full?
June 7, 20188 yr I think you need to leave the Axpert on but you can switch off mains breaker between the Axpert and the load. Regards Mark
June 10, 20188 yr I wouldn't switch the freezer off. Some don't like it and seals tend to perish. The draw, when not in use would be very little.
