![]() ![]() PmodbusToos V1.20 is very useful to get detailed information from the BMS of each pack to my laptop in my office via RS485 cable and adapter. I have no communication between the BMS and the inverters, the managing is done with the correct bulk and float charge voltage settings. In your case I would ask Averge to check it out. The difference of internal resistance between the packs is far more important. The latest pack I acquired is installed at the end of the row, yet it proves the strongest charge and discharge currents. I don't think the battery cables have any influence. Yes I have those Leoch batteries from the importer Averge and am happy for the time being - 2 to 2½ years of service, over 700 cycles. User has Leoch batteries and he uses a version of PBMSTools from his supplier to get the BMS info, maybe that is another option to try. I have not set up inverter comms (my battery is CAN not RS232), but I have set up comms to the seplos software via the RS485-A port to a PC with a 2 wire USB-RS485 adapter if you are interested in seeing exactly what the battery is doing. That bms looks suspiciously like a seplos. Could this be due to a wiring issue that the one battery is working a lot less than the others, is the problem battery the last in the stack? Do your positive and negative battery cables go from only 1 battery to the inverter or positive from the first and negative from the last (or visa versa)? Do you have any data cables between the batteries RS485 ports? ![]()
