Can I use a 32a RCBO in the AC input and a 50a RCBO on output 1 to supply all sockets in the van. Small set up, 3k Multiplus with a couple of sockets for 2kw induction hob and other normal 230v UK kit

RCBO’s on the input of Multiplus are liable to trip as the unit switches into charger mode. Provided that the inverter is properly earthed, I would only use the RCBO on the output.
