September 30, 20223 yr The protocol also change immediately when changing the dip switches, no need to power cycle the battery. Something to be aware of if something accidentally bumps the switch and it goes to Victron 250 the inverter might switch off, I haven't tested this, maybe Growatt will autodetect bit rate change, also if the cable is disconnected the inverter will switch off.
March 18, 20233 yr Thanks @RikusW for all your work and for the info on this. I ended up with a BlueNova RacPower battery too, and your CAN bus dumps and decoding work are super super helpful. Also great to know it changes protocol instantly (saved me lots of restarts switching and dumping CAN messages again!) I can read out the usual stuff (Voltage, temp, SoC, charge/discharge current/voltages) from it via CAN (thanks to you) and via RS485 (Voltronic LIB protocol). I see they support some of the Voltronic LIB protocol, but I'm super keen to get the cycle count and cell voltages too, did BlueNova ever get back to you with info? Thanks again everyone!
