November 23, 20214 yr Hi guys,new here...my long story..I have a water damaged Pylontech US2000B battery,new one replaced by insurance.I replaced the Comms card which is the card that got wet but still not giving comms to the Inverter.Any idea where I could get diagnostics done on the battery to find out the problem.I thought of replacing the power card but gave it a miss.
November 23, 20214 yr Hi Barrels. Do you have communication with the BMS itself? To be honnest, I do not know, how Pylontech is build, but from outside it looked like using a Seplos BMS. I use a Seplos with my own build battery pack 16x 200 AH prismatic cells. This BMS communicates with the Pylontech CAN protocoll with my Goodwe Hybrid Inverter GW3648D-ES and has a good software for real time view of the battery data as well as setting up the BMS. May be the software could be of help for you, but as I sayed above... Niels
November 24, 20214 yr Author Hi Nelis,the battery doesn't communicate with the inverter,even on it's own and not connected to the other batteries.It's definitely a batt problem.
