Hi all, could some one let me know if this is how PV is connected please ?
I was called out to a job with intermittent tripping today and after much ****ing about have sorted the problem.
My question is: they have had Solar PV installed in the garden this is apparently a 4kW system, and is 50 - 70 meters from the house. The inverter is placed along with the panels and feeds back to the house in 4 or 6mm cable ( I think it may be swa but can't see any armour in the fuse board) incoming feed within fuse board runs out through flex conduit into a a check meter and then from the meter back into the fuse board
and into the top of a 20A mcb.
Questions:
1) should there be an isolator between the the inverter and the meter in the house ?
2) should the output from the inverter be connected in the top of an mcb, meaning that if a fault develops and trips the main rcd the inverter is still supplying power to the board via the buss bar ?
Perhaps someone could explain the correct way to connect solar.
Many thanks.
