So are you running the two inverters together?

It seems to be a chicken and egg situation. I spoke to the DNO and they said I need to submit a G99 application for them to consider. I think I'll send one off and see what comes back.

The Victron Multiplus has certification for G99 but I don't believe it has for the G100 part. That is the bit I need guidance with. Is it just a case of choosing a different inverter which satisfies the G100 requirements?

I should add, I'm not actually interested in exporting to the grid, I think I can find ways of using the energy, even when my batteries are full. But <3.6kw inverter isn't going to cut it for me.

Hi. I'm new to all this so I am trying to find my way. I am just submitting a G99 application well in advance of installing solar on my new build. I just need help with the G100 part. I was planning on using something like a Victron 48/10000/140-100, mostly because I already have Victron gear on my boat and so familiarity etc. I don't have to, I haven't got to that stage yet. I need help getting this G99 application started. Can someone help me out with the G100 part and make suggestions. I don't expect the roof to be built for another couple of months but I am planning on 10.2kw PV and G98 isn't going to work for me. Do I need to be looking at alternative inverters or something else? Thanks

OK. So I am still G99 then. I'm hoping to cram 11kw on the roof and 3.6k isn't going to be enough for me.

This is something I haven't been able to establish. I don't currently care about exporting to the grid, I am only interested in keeping all the energy for my self. Are you saying there is a way of installing a > 3.6kw inverter but limiting its export to < 3.6kw and only having to submit a G98 and not go through the hoops of G99? If so how is the limit achieved and verified by National grid?

I live in the sticks and there will be two dwellings on the single run from the transformer. 1 is already connected and has a 6kw PV array so I don't know if the limit is due to the single cable running from the pole. I'm toying with the idea of limiting my inverter to g98 and having a second one dedicated to an off grid supply in the house. But I will see what a G99 application comes back with as that is the simplest solution. (if I can work out how to fill it in)

That is exactly what I am thinking. I have seen Solfit and made inquiries but what else can I consider?

I'm having an 18kva single phase supply.

I think I am going to have to go for G99 as I can't see 3.6k being enough. As for MCS 012 I'm still confused. My understanding is that GSE is MCS 012 compliant, many solar panels are MCS 012 compliant but NOT necessarily together, which is where I am at right now. But then if it is a DIY install MCS doesn't apply? Or does it?

Really? So I can get building regs sign off with GSE and a panel of my choice? I haven't seen that written anywhere but I am floundering around trying to get accurate information. If that is the case then I guess it makes it much easier. I certainly intend as much battery as I can afford. I was planning on not exporting to the grid but I think that means G99 application for a decent inverter, but I guess that is for another thread.

Hello. I am getting on with my self build house and was getting quotes for a 24 panel GSE in roof system when suddenly my supplier threw up the MCS 012 certification and the supply of solar panels approved for an installation. I was planning on doing the install myself, it doesn't seem that complicated, and I am only concentrating on the infrastructure for now. It makes sense to spend what funds I have on putting the solar on the roof at the build stage. Then this spanner has been thrown in the works. I have had a quote for JA solar and AIKO panels but I don't think I can install them as they don't meet the new requirements. So I joined this forum hoping someone can guide me through this. What are people's thoughts? For instance, does it make more sense to put a conventional roof on and not go with in roof? I don't want to because of the aesthetics but I need to look at all options given I don't have all the money in the world and I need to get building regs sign off. My goal is to cram as much solar on the roof as I can and I'm not interested in exporting to the grid, only running the house, if that is an important detail. ?
