4kw solar diy

Can I ask a slightly stupid question?

When putting in the battery, how is it physically connected to the house electrical circuit? Is it just a wire connector to an existing circuit (eg just wired into a plug/light? Or does it need to go back to the fuse board?

Trying to figure out how/where I could add in a battery to my home.

SO i can't just stick a battery anywhere in the house unless it can feed back to the consumer unit? Was hoping to put it in the utility where the boiler is, but i can't see how that would get to the consumer unit (stairs toilet are between the utility & consumer unit. )

cheers

That's the one I saw online. installer is refusing to sign. He's given me details of what to put on the form (none of it makes sense to me though).

Wonder if i sent it in without a signature, but with his details would it be accepted?

It was installed 7 years ago though.

Is he looking for his palm to be crossed with pieces of silver?

I am looking at something similar wrt mounting on the fence. Except my fence is higher up so I could potentially get a mount with a tilt. Any recommendation of where to get the brackets?

Your work has inspired me.

My first solar DIY foray is starting soon. Putting 4 panels on a quad microinverter on my folk's shed roof. Got 2nd hand 10 year old 250w panels and rails. Tested panels with a multimeter and they still work fine it seems (lower output as you'd expect for old panels). Threads like this gave me the courage and info to try it. If that works, I can scale it more for them. 

For those interested this one is €302 inc vat. https://www.rexelenergysolutions.ie/product/bpe-quad-microinverter/ (max 1.43kW AC output /1.6kW DC input). Kellighers can source the odds and sods you need. Rexel are the solar side of Kellighers afaik.

I know, I know, people will say a string inverter is more cost effective. But this works better as it's shaded and different orientations. And I'm learning DIY solar! And I can move this mircoinverter anywhere easily. I'd like to add more to a 1st floor roof so wanna see trial it all out in a small scale first.

I got solar installed at my own house with the grant 1.5years ago.

As low user of electricity this sounds like a cost effective way to add some solar to the house. Suppose will still need a sparks to connect microinverter to consumer unit? Also Nc6 required?

All I'll say is don't believe everything you read on the internet.

Best way to do it in my opinion. A lot cheaper than the grant route if you can do all the work bar the AC yourself.

I would also do the DC cables and fit the inverter, just get the RECI to finish.

I'm sure that you know that if you're doing that and expecting an NC6 off the sparks then you'd be well advised to agree it in advance.
