Go for the bigger inverter 5kw at least of you want to put more panels on the roof. I got the same setup plus zappi2 and hub for 7k after grant.

Managed to get the 5kw Inverter added to the original quote for free. Waiting on one more and im good to offer the project to someone. All prices are fairly similar with the Boards recommended suppliers.

One question i do have is, only one company mention the NC6 ESB form, does this be done as standard?

Yeah it's just a notification form sent to the esb networks, I think it even can be emailed. Just some details on the inverter that is installed and the mrpn of the meter.

Could you PM the "Boards recommended suppliers" please?

Any decent company should do this as normal practice.

Am I right in saying that the Solar PV grant from SEAI does not include anything towards the post installation BER?

irishchris · 04-11-2020 10:12am

Yep doesn't include anything in grant for any ber

So just finished off my system today and after a lot of researching and pricing here's my final system/cost...

18 no Canadian Solar 410w PERC Poly panels
1 BPE 5 KW Hybrid Dual MPPT inverter.
1 no safety isolating fireman's switch to solar panels.
All DC cabling and isolators.
All AC cabling and isolators
All protection devices required to inverter.
1 Battery to inverter. Pylon tec 2.4 kw including mounting bracket.

I should point out I've poor aspect and heavy tree shading on my main string so hence oversized panels vs inverter

Gross cost of €8,620, less grant of €3,000, net cost of €5,620
Excellent job, really knowledgeable chap, well open to questions and all the work was really neat.

slave1 · 04-11-2020 4:27pm

Oh, I also got a Zappi/Hub/Harvi install at the same time for an excellent price

04-11-2020 4:27pm

Er the attic is a hostile environment for electronics...

I see they weren't too bothered about cutting the ends off the cable ties either.
Battery isolator looks like a liability...don't disconnect it under load...plasma-tastic.
I fit disconnect rated isolators.

One day installers...:rolleyes:

slave1 · 04-11-2020 4:29pm

Only place for me, 70's semi with consumer unit in the hallway!

The humidity will take it's toll, shorter lifespan.
If it's got fans the digested dust will cause heat derating after a few months. Not the best practice.

I made the post in the spirit of showing others what things look like and also sharing costs so folk will know the ballpark figure..

It is an early photo so all the cable ties etc are now neat and tidy.
That battery disconnect is very sturdy, exactly how often will it be used?
I know the answer to that.

My attic is vented with controlled in/out ventilation as I store a lot of stuff up there I want to keep in good condition so your humidity comment is somewhat muted.
Inverter appears to have a large rear heatsink so no fan therefore no internal dust collection.

I'm refering to this comment more than anything.

The attic is more subject to humidity and temperature flunctuations than habited areas of the dwelling. This is pretty certain. Hence anything you put up there that is weather sensitive will not last as long as something in a stable environment.
Would you put a computer server up there too?

The battery with bms is vented though no?

That's not a battery disconnect it's a repurposed 3 phase fuse carriage by the looks of it. I doubt it's even DC rated. It's absolutely not a switch-disconnect.
How often do you need it?
Servicing and emergencies.
In the event of an emergency...after you clamber into the attic would you like your e-disconnect device to light the air with an arc of plasma baring in mind that emergency might be a source of explosive gas?

slave1 · 04-11-2020 5:19pm

LOL, your post is quite extreme, what gas, no gas in my house nor my neighbourhood, server in attic a good 10/12 years, never an issue.

Sorry I posted now

Come on Liam, don't piss in his cornflakes.

:):):)

04-11-2020 5:28pm

Batteries release explosive gas when fatally short circuited, punctured, charged when frozen, overcharged or develop internal faults, etc...

Those fuse carraiges are weapons in the wrong circumstances, I won't fit them. A lottov installers don't know any better.

Don't be sorry, you didn't install it, better be informed than not though?
That pylontech is IP20.

Well done @slave1, and even better for sharing your details with people who will appreciate the info you've provided.

i think you need go make a cup of tea or stick your finger in a socket...whichever is more convivial

Do you have a breakdown of the costs you can share with us?

04-11-2020 8:47pm

So it's ok to put inappropriate switchgear in an installation as long as you're nice about it and the client doesn't know any better?
Ignition protected switch disconnects cost the same as those fuse holders...

not a big tea drinker me...I don't mind sockets so much. Only one of the three options are potentially hazardous.

Edit:

Here's a contactor. [magnetic latching and IP version]
Here's a switch

None taken nor intended with any of my posts I focus on the technical not the personal.
Two things:
I do good business fixing other installers' work so power to their elbows!
thuther's I am a human voltmeter...I've had enough zaps now to be able to tell you the voltage ±15V by the bang of it!

Do you know where your fitter sourced the 410w panels?

I can't find any panels bigger than 360w

I don’t, I concentrated on the overall cost to me, the material/labour/profit element is something I simply never enquired about.

I don’t, I think it was up the North, I was originally going for 370w panels but there was a supply issue so I took a step back and said fek it and went for the bigger panels to max my roof utilisation and also compensate for my relatively poor aspect and tree shading.
The panels are 2m X 1m just to give you an idea
