On shore power, I have two Multiplus 3000s wired in split-phase (180) with the charging source off L1 for the Master and L2 for the Slave. I have 240 between L1 and L2 at the two Multis and when I go to charge, only the master will charge. The slave acts as a passthrough and the inverter light is lit with no charger light. The Master only the charger light is lit.
In config, it shows it is configured correctly (attached picture) and when you click into the Multi, it shows the Slave Multi ("not in phase"). Is it saying this because of split-phase and 180 out or do I have a setting incorrect? Also, when I click "Switch as group", neither the Master or the Slave will charge. Only by unclicking does it allow me to let the Master charge.
I've asked my Victron supplier and he has never set up Multipluses in split phase and has not idea. It would be great if someone from Victron can weigh in or let me know if this is the limitation of the Multis or what?
