Its communication hub between whatever inverter you have with BlueNova batteries

The CAN was a bought one the RS I made myself

Hello Rengo I used the CAN port

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

Hello Hannes Did you come right?

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?

Thank you for everyones replies, that makes sense, just weird that the inverter on some days shows it incorrectly and then other days it works 100%

Hello, I assume you talking about your master slave settings on the batteries?

Hello, I got a electrician to install a diode on my DB that connected on my geyser. The Diode is suppose to reduce the KW the geyser puts out. So the geyser is 4kw with the Diode it must only put out 2KW. The weird thing is when I check my solar it does not use 2KW it uses full 4KW and in some days and most days it does that and some days it does work with only 2KW. Why does this happens? Is it something I am not clearly understand?

I have found the problem, it was on my Wifi for some reason after firmware update on my router got more advanced setting for 2.4 wifi that did not work with the sunsynk dongle had to put wifi on Legacy for Legacy devices

Hello mzezman no wifi have changed, I checked the channels no issue there. We live far from other people so it should not interfere

Hello, I have my system for 7 months now and my datalogger always just worked. Now suddenly it keeps loosing connection from my wifi. Can any one help me with this or must i replace it under warranty?

Hello Coulumb thank you! I see the cycle charge is 14.4 - 14.7 So must I take the highest? 29,4? And the standby is 13.6-13.8 and 27.6V?
