February 19, 20233 yr Hi I would like to know if it is normal for battery voltage to drop from 55v to 54v over say 3 hours(no load and on eskom in that period, inverter runs as ups) and then charge back up to 55v. Ive got bluenova rac power bn52v 5.2k bp in parallel. The inverter is on the CAN port and bms seems to do the job. The inverter is a JSM 8KVA. Regards Eugene
