Apologies if I'm being thick, genuine question, why would you connect a battery to a consumer unit?

Ha - I've seen those footings before when I was searching google earth for something in nearby Drummore. If it's anything like this area, the Machars, just across Luce bay, it will be very wet. I don't know if that influences the full fill insulation decision. I'm building a timber frame extension with metal and timber cladding so not the same as yours. The stone walls of the original cottage here can get a bit damp sometimes though. As for trades, they seem to work in D&G time, they may show up when they say but almost certainly wont. My experience of getting a real man in for some plastering wasn't great. He was slow, not much cheaper than Oxfordshire, and not very good. I think there is little competition so there is no shortage of work and no real incentive to stay on top of their game. Tip, assuming you're not a local - for a long time I thought people thought my name was Ken. It turns out that Ken at the end of a sentence means something like 'you know'. Stranraer is a sh1t hole, (and that's coming from someone who lived near Didcot!) although it now has a screwfix and a Domino's so things are looking up. But my wife likes it here and land is cheap so you can buy some space around you. And the people are very nice. 🙂

He / She has a 3 phase system, so 16A per phase, 3 x 3.6 on G98. They state a 6kW array (panels), so could possibly be single phase 3.6 kW inverter legitamately over paneled on one phase, or could be a larger 3 ph inverter correctly installed over 3 phases, or a larger single phase inverter 'overloading' one phase, which might explain the installers actions.

My understanding is that g98 is 'install and notify', g99 is 'apply and get permission, then notify of commissioning' I don't see why you shouldn't be able to notify the DNO yourself of the g98 install. The form is easily downloadable, a guide is here https://www.enwl.co.uk/globalassets/get-connected/apply-for-a-new-connection/generation/micro-generation/guide-98_form-b-completion.pdf You can look up the type test ref for the inverter on the ena website. I've just done a g99, which is a bit more involved as it needs maps and line drawings. I would have thought a secretary at an installers could do a g98 notification in a couple of minutes. PS, They should have submitted it within 28 days of installation, suggest to them you will ask their certifying club to investigate.

Yes thanks. I'm also on the hunt for more ammo if anyone has experience of this with SP energy networks. I believe they also are a DNO for some areas 'down South'.

No, I said I was not fussed about how much export I was allowed. I won't get paid anyway as I've been waiting since Feb for Octopus to install a smart meter. They just keep saying no appointments available as a shortage of engineers. I chase them weekly. I intend to self use / store as much as I can.

That's interesting, boils my piss, they make the rules up as they go. SP energy networks (in Southern Scotland) have twice told me categorically that I must use an mcs accredited installer, the offer letter which details my export also states that. I suppose it could be that mine was G99, has anyone else with G99 appproval been compelled to go MCS? One other thing, I see there are lots of snazzy drawings in this thread. My DNO specifically asks fo a single line drawing, they are not interested in blue and brown lines representing line and neutral, or even pictures of the components, a labelled box will do. Cheers.

Well done. I take it you're not with SP energy networks in Southern Scotland then. They won't accept G99 on the portal. But they did accept an EVCP.

As a final follow up. I used 1 for the power factor, it has been approved. I still havent had a reply from hypervolt support, perhaps worth bearing in mind if you are in the market for a charger.

Thanks.

As part of the notification process to the DNO for an EV charger, I have to fill in a form which is asking for the power factor of the charger. The charger is a Hypervolt v3 home pro. Does anyone know what it would be for this charger. It isn't in the manual or spec sheet, I have emailed tech support at hypervolt but as yet have not had a reply. I have asked on the facebook page and no takers. A half decent gues would probably satisfy them, 0.8, 0.9, 1 ?? I believe with a home 7kW ac charger the car does most of the work, with the charger basically acting as a sort of fancy high current switch. Thanks.

I hadn't realised the max 550-600v was per string

Would 18 panels at about 40v max put the inverter over the maximin input voltage, or if connected series/parallel, put it over its max input current? I understand you can over power them in wattage but thought the max volts was absolute?

Just to bring this up again. I have looked througth the above regs and I cant see anywhere that it says that access panels or loft hatches are compulsory. Happy to accept that I've missed it ,so if someone could point me to the actual reg I'd be grateful. I can find stuff about the requirements if you do have one. I'd rather not, it's a trussed roof with virtually no room to move about and I have been fairly thorough in wrapping the house with tyvek airguard membrane to minimise ventillation losses. There is no requirement fo access for maintenance, only some 90mm MVHR ducting which is under 400mm of insulation. If I ever feel the need to poke my head up there I'll cut a hole and patch it again. Are they compulsory, and under which reg in Scotland? Thanks
