Regarding the noise of AC coupled inverter. I have decided that it will be better to site the battery and inverter in our porch. I can run 6mm SWA and the comms lead outside and get the electrician to drill a hole through the wall next to the CU.

Some good news: ITS technologies have confirmed they are in receipt of the battery for my order. They expect the Solis inverter on (y)1st August.

Why hasn't this been developed further? Seems like the tech has been around for years. 2014 according to the article.

It's always been about cost. Fossil fuels have been cheap, ignoring their environmental impact, until now. I wonder how the costs of Swansea/Cardiff bay lagoons stack up now. These projects would create good baseload production as they are not dependent on sun and wind. Moon energy!:) The...

In actual fact, it's more like 80% efficient though efforts continue to improve this figure. Only to be used when there is excess generation.

When I was at school in the 80's I remember a tv program talking about the hydrogen future. Electrolysis is like PV fifteen years ago: a promising technology that is still thought to be more expensive than the fossil fuel alternatives. But, as with PV, it is on a steeply declining cost curve...

Presumably it is used in the same way that geothermal energy is harnessed in countries like Iceland. The unit they have installed is a test unit. I imagine it is scaleable. Looks like a good cheap way of balancing the grid and storing excess renewable power,..., if we ever get to that point.:unsure:

Is this acceptable practice for the live feed?

Excellent. Thanks for that.:)

Oops, sorry. I'm showing my ignorance.:( However, getting a qualified electrician to do the notifications is correct?

Hi there I was/am in the same situation as you. I would suggest: Decide what you want to do. Then contact your DNO by email so that you have a record of the relevant application, equipment certificates, and schematics they want. Some of the electrical work you need to do on the AC side will...

Good. That's a relief.:). Western Power specify that islanding is not allowed if I remember rightly, so I wasn't planning to use that anyway. Do I have to use SWA as the setup is going to be indoors? The manual for this 3kw inverter specifies 6-12mm cable which seems overkill if the inverter is...

The inverter needs grid and backup cable. So will I need 2 mcbs for that alone? In which case a mini CU will be needed. Also recommended 6mm2 cable seems a bit heavy duty for 3kw?

Sorry. Non-sparky.:). I mean the live feed and the copper strip that feeds into the bottom of the mcb's.

Will check with Solis. Cheers for the heads up. (y) Though if my CU is rearranged there will be no RCD other than the inbuilt ones.

Ah yeah. That all makes sense. Thank you. Looking at my CU then. How would the electrician feed neutral and positive to the grid side whilst maintaining mcb protection. Is it acceptable to trim the common positive feed to the solar and battery mcbs and run some cable between them and the grid feed?

Thanks Binky. Just to confirm if you don't mind? :) If I rearrange the board. Am I right in thinking that my electrician will be redirecting the neutral from the solar circuit to the grid side of the rcd? Would the new inverter for the battery storage need to be connected similarly? The solar...

Morning all. Sorry for the late supply of this picture showing our CU. I suspect you will tell me that it's no longer up to regs, as the solar shares an RCD? Just the 2 neutral bars, but space to put another in? What are my options folks? I need to put it right, and connect the inverter for the...

Hey folks, thanks for all your input. Unfortunately, I'm now away for 7-10 days and haven't had a chance to have a look at the CU. I'll check as soon as I get back. Will need to pick your brains again.:D.

That's not what I wanted to hear Steptoe!:(. So this isn't going to be as easy as I thought it would be? Are you saying I need to split the incoming tails for a totally separate consumer unit or install a sub-consumer unit? I'm glad you brought this to my attention. Definately, notifiable work...
