[QUOTE="revor, post: 509654, member: 23254"] Thanks Binky will do it without an RCD. I had already put in an isolator for the inverter in the house plant room. I have also put in a changeover switch for the CU which is powered by the battery in the event of a grid outage because if the inverter goes down then no power goes to this privileged loads CU so the changeover means I can put the CU onto the grid if inverter goed down. The inverter powers this CU either via battery (if no grid) or via the grid but the load is limited to 20 A off the battery and 32 A on grid. I will put the lighter demands on this CU lights, heating ,MVHR, freezer and telly and 1 ring. I have already had the OK from the DNO, a local installer has been extremely helpful in doing the application for me and were going to do the MCS for me if their electrician got involved, who is not on their books, but contracts to them when he is needed for connecting up etc. As that has not happened in all probability now that won't happen and as previously mentioned the economics is not there. I had not really wanted to do all the work myself as have a build to finish but no one was really interested in installing my choice of gear. Think it was out of their comfort zone not having heard of the inverter or battery or maybe just too many unknowns. [/QUOTE]
