I have an inverter charger multiplus II, a smart battery protect and smart solar regulator connected to a LifePo4 battery in a camper van. When I'm charging the battery from the 220V socket at home and the battery is full, an alarm from VE.Bus System appears in VRM saying "Overload L1: Warning" and the battery protect turns off everything. If I disconnect the inverter or the cable it works again, but sometimes this happens also with the solar charger and I had to reconnect the solar charger from VictronConnect app for having my installation working again.
I tried with different cables and plugs with same result.
Could someone help me to find the issue?
Thanks!
