Hi guys

Working with a Marine Installer. we are having difficulty getting the VRM to replicate what is happening on the vessel.
The Smart BMS is in the BMS-Can, The MultiPlus is in the VE.Bus and the Skylla in the VE.Can with terminator.

In the VRM view IU can see all the devices are connected via “device list” however on the dashboard, the “Battery BMS” is showing correctly, voltage, amps TTG etc. However the Inverter Charger is showing “Off” on the dashboard, when it on, we can charge via AC input, run AC loads, but these dashboard and overview on the Touch 50 are not correct. What are we missing?

The Smart BMS should also have a terminator. If the Smart BMS is connected to the Cerbo BMS CAN port then this needs setting to VE CAN and you should have a terminator in the unused Cerno BMS CAN port. You should also have a terminator in the unused VE CAN port. As all devices are VE CAN, they can all be in the VE CAN ports on the Cerbo, daisy chained and both ports need to be set for 250kbps VE CAN.
