Yesterday, I connected shore power to my campervan for the first time. I've been running my Multiplus II over summer with the MPPT 100/50 as my sole power source. With land power connected, the Multi charges the battery with >100A but the AC in current does not show, nor does powerassist work. Anyone can suggest a possible cause? With land current disconnected, the shown AC load power is correct, but with the relay closed all AC shows zero regardless of the actual load. In below screen shot I was drawing at least 1500W AC
