Hello everyone,
I had a situation the other day, my batteries were very low, the whole system was shut off, probably the low voltage cut off was reached.
I decided to plug in to shore power to charge the system - nothing. Started to check everywhere if there was voltage, everything looked fine. My Multiplus switch is set up in the "ON" position from the switch. I also run a Cerbo GX, and I turn ON and OFF the inverter from there. I'm not sure if the inverter was on during the drainage of the batteries, or OFF. Could it be if it was OFF, that the shore power could not charge the batteries, because the inverter is not in ON (charge) mode?
The way I got around that, is that I have an Orion DC/DC charger, I switched it on and some power came on, and I don't remember if I had to turn on the Multiplus from the Cerbo Touch, but got it to charge.
