[QUOTE="binky, post: 536374, member: 490"] Local standards IE BS7671 says MCB. The whole bit about leaking DC down the cct and confusing RCDs is linked to DC currents confusing shared RCDs. Most modern appliances have electronics protected by ' smoothing ccts' which leak a little leccy down the earthing. Lots of DC leakage from lots of appliances or IT equipment can confuse RCDs apparently. Your solar/ battery needs to be on it's own cct not sharing any form of RCD protection with any other cct, so the DC leakage is irrelevant, and if you did have serious fault within the inverter, it will probably do something very scary involving lots of conversion of leccy into smoke and blow internal and external fuses.
