Connecting my REC BMS to a Victron Cerbo

The CANBus connection to the Victron BMS is pretty straight forward but there are a couple of things you need to know.  We will update this topic as new issues come to light, and we will add them to this first page, so feel free to leave your questions here.


The REC BMS can form an integral part of a networked Victron Energy System by working together with your inverter, MPPTs and chargers to help avoid hard shutdowns.

"In the REC manual it gives you the settings that you need to configure within the CERBO remote console. One difference I found was to plug into the VE-CAN port on the CERBO rather than the BMS-CAN port and set CAN-1 settings to VE.CAN & CAN-bus BMS (250 kbit/s). You can set this at: Settings/Services"
