Conflicting information from electricians. Help needed

[Mike 134]

Do people not give anyone benefit of doubt any more. I'm entitled to rest breaks on a 12 hour shift ya know! lol. Anyway - does anyone have any advice on how 3 single phase inverters and batteries should be wired up?

From this side of the Atlantic I'm afraid I can't help you even though I'm a master Electrician. Europe has different voltages used, and 3 phase is more common there than here for residential use.


Good luck.

Incredibly perceptive of you Mike it's now 03:50 and I'm coming towards the end of my 12 hour night shift - at least it gives my car time to charge on company electric lol

So, you're doing this on company time, right ?
If so, it might not be a good idea to make it public knowledge.
Just sayin'.

Hi Mike

i don't have anything like that. Is that a requirement in the uk??

I'm in the USA so have no idea what the UK permitting requirements are. A one line drawing shows all the various components and how they are all connected together which would help answer your question.

By the way you're up late must be about 3:00am your time?

Before anyone can give an answer based on fact and not a wild a** guess, could you post the one-line diagram that you would have in the permit prints?

Thanks

Hi

i had solar installed in Feb. There are 44 panels 3 single phase lux power inverters and 3 3kw batteries (one on each phase)
the installer tells us the only way to get more efficiency is to balance the load more around the house but when we had a car charger installed that should have taken excess power from all 3 phases and pushed it into the car it was only recognising one phase. The electrician had a look at our system and said that it's not sharing power because they haven't linked them up with data cables. The installer insists that power cannot be shared between phases.
please help, I don't know who to trust
