Bluenova Battery BMS Not Connected

I have 3 sites which have been installed over the past month which randomly disconnect from the battery BMS. All of the sites have 3 x 15kva quattros and Bluenova Batteries. Randomly the batteries disconnect however resetting the battery does not solve the issue. Only resetting the Cerbo GX allows the battery to be redetected. Any idea what could be the solution.

Hi Nick

I updated to 2.93 and it didnt help. then downgraded to 2.85 because 2.94 was not available. I will update it now and see if it helps. Thanks

There is a fix for a CAN BMS issue that occasionally happens.

Failing this, check your bus is properly terminated else BlueNova have a BMS issue and you will need to take this up with their support.

also check that the bluenova bms has a diferant can instance for each battery, this is also a possible cause.
