September 8, 20232 yr Hello I need urgent expert advice please, none Sunsynk or Bluenova wants to assist me. I have Sunsynk 8kw inverter with 2 BN52V-100-5.2k DU batteries connected in parallel and connected with CAN port. The system have been running for a year 100%. A Week ago the BMS on inverter just get stuck so I cant see the SOC of the batteries or what the batteries is currently doing. Rebooting the system it works again but only for like 4 hours and it freeze again. What could cause this? Sunsynk checked and they say they dont see any issue and say I have to upgrade battery firmware. Is this a inverter issue or battery issue and is it possible to upgrade firmware of batteries?
September 19, 20232 yr Author For anyone with this issue, I got it resolved by resetting my Inverter to factory default. But its also recommended from BlueNova to install a Bmac. I have ordered one just to be supported
March 19, 20242 yr Hi @Gman007, did you go and buy the BMAC? Before getting the BMAC, which cable did you use between the Sunsync and the Bluenova batteries please?
