On-grid domestic battery storage

Exiled_Tyke

Yes, but it isn't always so clear cut - Ok so my circumstances are unusual but for me at least there is a way.  My PV and battery set up are paying for themselves quite nicely - and as others have said for this year at least better than expected.  I get FIT and use Octopus Go for import so I"m not going to move to an SEG tariff.  

On a sunny day (with passing occasional cloud) the house battery can be used to smoothen out the peaks and troughs into the car battery knowing that the overall day will be adequate to keep the house battery full and trickle charge the car battery at whatever rate I choose as most appropriate (6amps and up).  Any excess top up can be done overnight.   

So it's a benefit of the PV and battery set up I didn't anticipate. However, I agree, not a sole reason for going down the PV route but  as PV is looking more and more worthwhile, I think it could be an extra 'business case' for those with a BEV.

To get DNO approval, you will need an MSC certificate.

For clarification: I'm talking about an AC connected battery storage system - I have a separate solar PV system, for which an MCS certificate already exists.

So, my understanding is that I need to apply for DNO approval for the battery system connection. Is that right?

Yes, I think that's correct. The AC-coupled system will need its own MCS certificate (or the equivalent from one of the other certification bodies).

That interesting my installer is MCS NAPIT for solar systems but not NAPIT for battery banks, in October they fitted a Solax AC 5.8 battery bank to my existing 4.4 kWh solar array

It depends on what the cost is? My guess would be around £6500.

Ohhhh man :O missed it out! Cost - 5.12kWh x 2 Battery Storage System £7954.00

The kit costs £5K so I would say that £3K for sundries & fitting is too much. Half that figure would be generous imo.

Appreciate the info, any advice or opinions greatly received at my end

I`m still in discussion with them, but I can`t see them dropping as far as £6.5k. From the off I`d hoped for a price in that region as well.

If they are vat registered, there is 1.3k of Vat on that price

Are they not loans rather than grants? Could still be useful
