Never connect a (big) inverter to a BatteryProtect!
You probably kill it. Read the manual!
(also the MultiPlus can push current through the BP in reverse which isn’t allowed)
The MultiPlus is controlled via the Cerbo GX.
The ATC and ATD contacts are dry,. that means you have to connect + to one side if you want to control the cyrix.
Hello Matthias, Thanks for a quick reply. Maybe me scheme is missleading. The “inverter” in the top part of the picture is “only” the service, it will pull energy from the system, so when you attach shorepower there is no voltage over the “out” BP terminal. The charging is the lower right part (apart from the MPPT that is after the BP and controlled by the Gerbo )where you have the Panda /generator & shore power, this is pushing energi into the lead batteries and then further into the Litium through the Cyrix-li. The cyrix-ct is separating the lead side thruster/start batteries. If I got it right my Multiplus is to old for cummunication with Gerbo since it is a 2011 with firmware version v125 (hardware outdated), that is partly why my intetion was to use a BP on the load-side and a Cyrix-li on the charge side controlled by the BMS. Any tips is very much appriciated if there is a better way. But for the ATD and ATC to work I used the below scheme from Victron for the BP (PIC 1) but also attached the GRD, should I but a jumper from 1 to 5 and use “+” from AUX instead? and re-connect terminal 6 to H on the BP?
For the Cyrix I assume I should link Port 85 to ATC terminal 4 and put a jumper between terminal 1 and 3 to get “+”?
