Quattro 15 kVA + 3 Dyness Powerbox G2 batteries in Ireland

Hi everyone,

I just got my system set up about two weeks ago and I am delighted with it. The Quattro is a charging and inverting beast! Now I can run my house off the battery. Since my house is fully electric (including a heat pump, electric cooking, etc.), handling the load is no problem.

I also have an EV charger, but that is on the grid side; so if I do get a power cut, that will be outside the backup system. The electrician also wired up a plug for a generator, just in case.

The board came pre-made from my supplier, so it was just a case of bolting it to the wall (which I did myself and was not a small job! :grinning_face: ). The board also has space and is wired for an MPPT if I want to expand my PV array in the future.

At the moment, I love messing around with Node-RED. I’m building bespoke charging strategies, including a ‘storm watch’ feature. I also added a facility where, if I get advance notice of a grid outage, I can input the date and the system will charge and hold the battery before that time.

Very nice and clean Setup :+1:

and nice “touch fields” :grinning_face: You never know what’s coming …

‘The Field’ Storm Mode sounds like… you’re waiting for the next thunderstorm and lightning … and then feeding the energy directly into your storage system. :high_voltage: :grin: … bzzzzzz

Something like in Back to the future; a bolt of lighting feeds the Victron Flux Capacitor…

At some point, Victron may introduce the new Victron Multiflux…
The first two models have disappeared somewhere… :thinking:

But only for 3-phase systems !!!

I’m also in Ireland though with a much smaller system of Quattro II 5k for ESS. Could you share more about how you achieved the earthing and any grid compliance here in Ireland?

I also got a pre-built board from a Victron partner and installation by qualified electrician.

I just want to be a little more certain it was all done correctly given I think we’re a relatively small user community in Ireland.

I appreciate you’ve the Ziehl on your setup whereas for me the ground relay is in my Quattro but maybe the principles carry over?

congratulations on your setup!

Here is the layout of my system, I’m not an electrician by any means so this was installed by a RECI electrician and this schematic was designed by my supplier who was an electrical engineer. There are one or two differences to this in that I changed the 16mm2 cabling to 25mm2 cabling just to be sure as I have a 16 kVA connection. I also have an 80Amp MCB breaker. Otherwise its installed as design below.

Have you any schematic of your installation jcirl? Did you get the nc6 overthe line ok? Hope to do the same in the new year!

Well done Eco_Mental. Whole system is future proofed.

I’m planning to do something similar in the next few months. I would be grateful if you could advise me on a couple of questions.

  1. Is your generator plug wired into the generator port of the quattro?
  2. Who was your supplier of pre-made board and might i ask about relative cost for this?
  3. Was the NC7 hard to get? Pity you have to apply for it giving that you can limit export to 5.5 KW. Fear is 1000euro will be down the drain if they reject me.
  4. Will EV charger not work off PV dynamic on your inverter. Im AC coupling my Huawei into AC 1 port. My huawei charger is coupled to my subboard AC supply. Technically the inverter mode on the quattro should kick in to give charger power.
  5. Is there a particular reason you went for Dyness batteries?

Sorry for all the questions, i’m not an electrician or installer so am quite green to the area.

  1. My Current set up:

My proposed addition:

Mounting Type Ground-mount
Panels 14 × 445 W Trina bifacial
Capacity 6.23 kWp
Orientation South-facing
Connection DC-coupled to Victron MPPT
Total PV After Upgrade 12.71 kWp

All the best,

Hey Eco_Mental. If you get a chance can you get back to me. Alot of peeps i m talking to are saying i wont get approved for a 15kw Quattro. I have the same setup as you EV, A2W HP, 16KVa MIC. Really interested to see how you got your project off the ground.

HI Joe90

Appogies for not getting back I didnt forget about you its just my father-in-law passed away last week and I had funerals etc…and I am only getting back up and running now. I will reply to your post above. But just quickly the Quattro 15kVA is approved on the ESBN Low carbon register as a generation device and export limiting so the Quattro will NOT stop you. Once on this register all the grid specifications are passed for this invereter and is approved for connection to the grid. Low Carbon Technology (LCT) register | ESB Networks

The the only reason you wont get appoved is the check the network engineers do to check the actual grid infrastructure such as your local transformer has it the spare capacity to export to this. If you check this interactive map you can see your local trasformer Availability capacity heatmap | ESB Networks That saying if you already have an NC6 you should be approved for exporting up to 5.75kW (roughly..25Amps I think) so the worst you will get is that. But you have the extra grunt to charge and invert your AC loads, being export limiting you can have the 15kVa Quattro no problem.

See here if you select generation it tells you how much spare capacity is on the transfomer

ESB LCT Register Quattro 15kVA approved

I’m sorry to hear that. Puts things into perspective really. My condolences to you, Wife and family. May he rest in peace.

Thanks for the reply. Its alot more positive than i had anticipated. Its great the Quattro 15Kva is now on the register too. Thank you for the hard work on this. I’ve looked up my closest transformer. 50kVA available it seems. That would be more than sufficient.

HI Joe

Following up on my previous post hope I answered your queries below and in my other post

Alot of great info there. Ill get onto suppliers and get prices, get NC7 form in etc. Full steam ahead with this now. Your set up is ideal for my situation. Your laughing by pulling 18KW from pinergy over night. :slight_smile: They will increase the price next year on account of this. :laughing:

Before you submitted NC7 form did you have a pre-meeting with them to get an idea of success?

For the back up (inverter mode) did you have to run a 25 or 16mm2 to the meter box or was the AC grid side of the main board good enough to clamp onto from inverter?

Ill only have the EV Huawei charger set to PV Preferred and hopefully wont need to go down stealing from batteries unless an emergency arises.

No I didnt have any pre meeting regarding the NC7 I think they are too busy for that. From what hear some people are just putting in the higher rated inverters if they already have an NC6 and just limiting their export to the NC6 MEC eg 5.5kW……so long as you dont export more than 5.5kWh per hour who is to know!!!

I presume you have 25mm2 going to your main board if you have a 16kVA connection. When installing the quattro it was specified 16mm2 for all the connections which is ok for 63Amp and even 80Amp, but I made my electrican put in 25mm2 to and from the quattro and the board. I just wanted to be future proofed if I ever wanted to up my connection again 25mm2 is good maybe upto 100Amp. For a small extra cost it was worth it. I got a Flir Camera and did some IR shots of everthing at full load and there were no hot spots of concern at full load. In fact the highest temp on my board was the Victorn Energy meter and the door bell transformer :smiling_face_with_sunglasses: so I can sleep easy.

Hi there, sorry I forgot all about this forum with the Christmas holidays!

I don’t think the NC6 is that strict - my electrician just provided the 50549 certificate and filled in the other specs and we were granted the 25A MEC a few weeks later. There wasn’t a lot more to it than that.

Because my electrician doesn’t do half-a-job he has fitted in a NC safety switch at the meter cabinet that uses the Emergency assistant on the Quattro-2. That also kills the PV/MPPT too.

We also have a changeover switch to just bypass all the renewables in the house and reconnect to the grid like a regular house.

You reminded me I do need a proper schematic of this. Especially when I see the beautiful one that @Eco_Mental just shared :grinning_face:
