I have a Cerbo GX and three Multiplus-II in a three-phase system configured.
When I switch off the Multiplus over the remote console it turns immediately off.
Switching back to ON (remote console) has no affects.
To bring the Multiplus on again I must pull VE.Bus cabel out of Cerbo and the Multiplus starts few seconds later.
After reconnecting the VE.Bus cable it is all fine. Switching between Charging Only, Inverting Only and ON is no problem and works fine.
When I’m using the MK3-USB Adapter and the VictronConnect Application, the switching between ON and OFF works fine.
