Assuming I have a 16th edition main consumer unit (actually a split board with an RCD and a few non-RCD circuits for things like the alarm system, smoke alarms and freezer, but I digress) ... and I want to move forward to a hybrid solar inverter, infeed only, so it will be some form of hybrid inverter.
I have an incoming isolator, with SPD that feeds the existing board. The plan was to have a small board installed to 18th edition, so metal clad, grommet etc and maybe 4 ways and a doup0le pole isolator, no RCD ... 2 ways with 40A RCBOs feeding the existign electric showers, one way with an MCB feeding power to the hybrid inverter and a spare. Does that sound about right so far?
The hybrid inverter would then power the existing consumer unit. I was thinking of asking for a 2 way changeover on the input to the old consumer unit, so it could be switched back to the incoming mains (there are spare ways on the Henley blocks) if the inverter craps itself or runs off screaming. Would there we a requirement to bring the whole consumer unit up to 18th edition at the same time or can it be left as is?
