RichardJH Posted May 21, 2023 Posted May 21, 2023 I have a Mecer 8kva inverter with lead acid batteries and wish to replace with a Pylontech UP5000 battery. The communication cable supplied with the battery is used to link batteries together and is wired as a standard ethernet cable. However the Pylontech manual indicates that the BMS cable between invertor and battery has pins 1-3 “NULL” which presumably means not connected. That’s fine but is the wiring configuration at the invertor end? Alternatively does anyone know whether Mecer have their own BMS cable and if so how to get it? Quote
