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?
