G59/3

[Mark.W]

Morning Guys

I have had a look around on here but can't seem to find what I am looking for.

I need to know what the latest is regarding G59/3 inverters and whether we still need to use a g59 relay!

I have read that 5 or more inverters still require an additional g59 relay, but 4 or less don't.

Please could some kind soul point me in the right direction.

Many Thanks
Mark

G59/3 only applies to systems 50kW or below so if your total system size is above this you will still need the relay

Its up to your DNO to tell if they require a G59 relay. As long as the inverters are G59 you may not need one.
