Just purchased a Victron Multiplus and Cerbo Gx to upgrade my caravan solar system. I have them all connected and online on my VRM and I can’t get any AC to go into the Multiplus. I have 230v at the AC input plug but my Multiplus won’t switch to charge or pass through it’s just staying in Inverter mode permanently but I can hear a relay clicking inside but nothing is changing over. I have tried remote configuration and my charger is enabled etc so at a lost end.
