MultiPlus II settings

Hi.

Our RV system uses the following Victron gear, running 240VAC. Can anyone help with the correct settings for the MultiPlus (v552) and CERBO (v3.37) please. i.e DVCC settings, as a warrning keeps appearing on the cERBO saying that the MultiPlus is in overload, even though a fridge and TV are the only appliances running.

Cerbo+Touch Cerbo GX + Touch 50
Orion-Tr 48/24-12A (280W)
MultiPlus-II 48/5000/70-50
SmartSolar MPPT 150/70-Tr
PYLONTECH US3000C x 4

Thank you.
