We have 2x 120 12 v AGM batteries in parellel so 240 amp the fridge draws on average 4 amps per hour , we are fully charged by sunset . Now I would expect to see consumed amp hours by the morning as the fridge has been cycling and tv been on ect . Now in the morning the BMV reads 1 amp hour consumed soc 100% the voltage says 12.8 surely this cannot be correct . We are at a loss now on how to fix it the wiring at the batteries we feel is correct. Any input would be greatly appreciated.
