September 27, 20232 yr Good day I have a Fivestar FS-G01-48200 battery 10KWH 51.2V but i can't get comms from the BMS on a Sunsynk 5KW inverter but i think it could be a old firmware installation on the battery but I have called and contacted everyone that sells or mentions Fivestar but no luck no one knows how or where to get the newer version, so I'm hoping someone here might have some light to shed on this, pictures attached.
