I have a small diy solar setup with 4x400w panels that for most of the day produce more than I consume. I’ve added 3 90 amp flooded lead acid batteries in series (36V) to save this excess, but I don’t seem to be getting much of a return for all the effort. The batteries charge and discharge fine, and the efficiency seems all good, but I never get much more than 400-watt hours before reaching what I believe is the safe cutoff point of 12.3 volts on each battery.
My question is; is this safe value of 12.3 volts measured on load or in a rested state? I’ve searched the various battery sites for the answer to this but can’t find an answer so any help would be appreciated.
