Wich Victron devices need a type B RCD?
I have read many updated manuals from your web and there might be some contradictions.
In devices such as Quattro, Multiplus and Multiplus II there is nothing about type A or B RCDs, only the sentence:
"An earth leakage circuit breaker and a fuse or circuit breaker rated to support the expected load must be included in series with the output".
While in MultiGrid and EcoMulti there is the sentence:
"This product can cause a d.c. current in the external protective earthing conductor. Where a residual current-operated protective (RCD) or monitoring (RCM) device is used for protection in a case of direct or indirect contact, only an RCD or RCM of Type B is allowed on the supply side of this product".
