[QUOTE="condor22, post: 597571, member: 1932"] How old are your 2 x 115 AH AGMs, if you don't mind me asking? I ask as, 44 AH of fridge use from a 230 AH bank is only about 20% of capacity. I use around 37 AH from my 130 AH a day on average and that's around 28% of capacity. When I get up in the morning, I usually have the panels working a little and also turn the diesel heater off, so battery state voltage is not at rest. But a couple of times I've turned the panels off the night before, to check the morning voltage. As I make brekky using LPG, I actually have no load on the battery at all and it hovers at 12.5 V until I turn the panels on. I do know that my BMS has a parasitic load, so if I turn all loads and charging off, but leave it on, it slowly drains the battery. It's LCD display has a timeout function, I've set to 10 minutes. After this it has a current drain of 1.5 mAh = 36 mAh over a day, not worth considering as I leave the panels on all the time anyway. :) [/QUOTE]
