Multiplus II not charging

Hello all,

My Multiplus-II/Cerbo/Batrium ESS-setup is not charging anymore and I'm looking for reasons why that happens but have a hard time finding the root-cause. The GX says it is on Scheduled Charging / bulk (setup by me) but there is no current going into the batteries. The Batrium's charging state is ON, therefor I see no reason for the Multiplus not to start charging. If I set ESS to 'keep batteries charged' the Multiplus goes into Passthru.

My main question is: where to look for the cause?

Guess I found it! Did a complete reset of the MP and re-enabled ESS. System started charging again. Thereafter able to reproduce by enabling DCVV. Seems this breaks my config... I noticed the message to Reset de VE.bus. Can someone explain how to do that? On which device? Been through every menu but did not notice this option. TIA!

Not sure if this has anything to do with it. But you reset everything except the Cerbo.

May be it is worth a try? Then do whatever it is to set up the Batrium again with the Cerbo.

Thanks Alexandra! That procedure seems a little too much for my issue. I've read something about resetting VE.bus with modbus and applying a value on this forum, but it didn't mention where this was to be found.
