My last 'non Amd 3' CU Install.

[Midwest]

Seen as this thread has become a bit of a "bitch fight" in regards of other members installs. I'll post this one up for you all to get your teeth into. No holds barred, say what you want, any pointers that you post up will be taken in good spirit and as an education from the more experienced members.

I would if I had the foggiest at what I was looking at.

DC isos are integrated into those inverters, AC is within 3m of the distro boards, so doesn't need local isolation as well.

On the Ac side does it need 4 pole isolation ?
Also as good as sunny boys are I don't like the built in dc disconnect and would also prefer an obvious iso up front just for isolation.

Good question, 4 pole AC Iso at the DB within reach and the DC Iso is on the inverter and labeled up. There is also DC Iso fused units on the roof.

Plus (down stream) there is 2 x 100A 1361 3ph fused Iso switches going into the main DB and then protected by a 200A 60947... Plenty of protection, just a pain putting labels on every bloody box in the transformer room/plant room lol.
