Nice Pv Jobs

[fiardor]

Just a few of mine.

The first photo has a glaring AC over sight that has now been rectified but if anyone can guess what it was Earthstore has offered to buy us all a round of beer!
HEE HEE i can hear his jaw hitting the floor as he reads this :furious3:

Answers on a post card LOL

apart from it being switched off, it seems to be using some form of black flex cable instead of twin and earth. and it seems fairly small as well.

is that it?

Enecsys are great until one packs up.
The original batch of inverters were poor so we are constantly having to replace them(Enecsys pay of course).

So i asked Enecsys if we could mount inverters on the inside of the roof and they couldnt see why not so thats what i know do.
Sorts out all sorts of future issues.

The black cable is FP200 as it has a 2.5mm earth as opposed to a 1.5mm in T+E which i prefer (lower Zs)

The cable runs 3 metres up outside of building hence the use of this UV protected cable.

So no but i like your style Gav.

I was gonna say yes just so we get a pint off Earth LOL

hmm...

knowing those inverters can be trixxy buggers to wire up first time then, I'm going with you'd wired the sockets up with reverse polarity as you wired positive into position 1 as would be logical for anyone other than the germans apparently...?

Nein meine Freund PMSL

Dont hate me Gav but it is an SMA AC guidline :13:

 

[Earthstore]

Firstly, I would like to say this is what all PV systems should look like, they are a credit to you, it is good to see someone that takes pride in their work.

Hmmm, the AC thingy, is it that you can not turn each inverter off independently, of course we can not see how they are connected up inside, or am I buying the drinks?

oh yes, of course it is.

34.16KWP, Suntech 280 panels, installed Dec 2011, (just in time phew)

CSA of the AC cable too small, especially when shared between two inverters?
You've now either installed a second supply or a larger cable?

That's a fantastic looking installation!
Lots of attention to detail there.

 

[fiardor]

Damn you Earth.

Keep your money LOL

Yes i had to separate the inverter supply as per sma guidelines and upgrade the supply to 4mm swa (although sma do stipulate 6mm!!)

And your photos are quite frankly inspiring Sir.
Nice, very nice.

 

[Gavin A]

if we're doing commercial PV installs...

26kWp on this roof installed in November, and another 21kWp or so on the opposite roof face installed in March once DNO permission had been received.

Rail extensions below the panels were needed to spread the load better across the steel work below.

I was pretty impressed that we managed to work from both ends into the middle (for speed) and get both sides to within a few mm of each other over 60m of roof.

I probably ought to go back and get some photos showing both sides at once, and without working installers and associated debris on the roof.

hold on, that was what I was getting at in my first post.

and it seems fairly small as well.

that's got to be worth half a pint at least surely?

Lol yeah sorry Gav I'll drink to that bud
