Advice on RCD and MCB selection; input and output for Multiplus inverter/charger?

The 1.2kW Multiplus example schematic, which is similar to my own setup, suggests RCD and MCB on input and output of AC; it seems logical that both sides are protected for situations where there is no RCD/MCB in the hookup point (?)

From reading the datasheets and guides, I was thinking of using a type A RCD on the input to the multiplus and type B for the outputs (loads inside campervan) because type B may give extra protection for inverter failure modes? type A are also cheaper so if they fit the requirements, jobs a carrot ;-)

Any advice* on RCD/MCB selection would be appreciated.

* While I am asking for advice, I am responsible for my own actions and decisions WRT mains voltages; Im well aware of the dangers!
