Hi all, searched the forum for any info on this but to no avail...
I have been installing PV systems for ages now, and have been connecting the AC cable to an MCB on the RCD side of the consumer unit whenever there is a spare way..
I spoke to another installer and he told me that this cant be done, the cable must be connected to an MCB an RCD protected garage unit which is fed via tails taken from the main switch or link boxes, because under fault conditions if the RCD trips the inverter will still be producing power for up to 5 minutes, and the busbar (and circuits) will still be live.
A way to get round this is to install an RCBO in the consumer unit, but there is not always a spare way on the non-RCD side...
Dont the inverters have a shut-off built in in the absence of an AC input?
Can anyone shed any light on this?
Cheers!
