Please can someone from Victron update us on plans to get G100/2 compliance.
TIA
Hi Jack, historically we havenât seen much comment on certification plans on the community.
You may be better off contacting your area sales manager - contact details on the main site.
The community is rarely the source of plans or roadmaps.
Brilliant, Cheers Nick. I have reached out to the UK sales guys so will report back.
As expected have heard nothing back from either of the Victron UK Sales Managers. Might be of benefit for Victron if they actually communicate and build a relationship with Installers.
Hi @JackAspeyEnergy,
Regional certification is a bit of an ever green topic and source of frustration on all sides.
There is often imperfect information, and not a clear answer.
Iâll reach out to the UK team myself as well to see if there is anything to report, but itâs also possible there isnât a clear statement of the situation yet.
The decision has been made not to gain G100/2 compliance. The decision was made based on our historic sales numbers prior to G100/2, the engineering time required and the commercial reward.
We do of course have G98 & G99. If feeding in to the Grid is required then the most popular option is to use the 5KVa models, configfure to Grid code G98 restricting the feed in and load out to 3.68Kw.

Hi Nigel, appreciate the clarification although not what we and most UK folks would want to hear.
We believe one off the biggest selling points for Victron is the ability for full house back up. However 5kW of inverter power simply isnât enough in 95% of instanceâs.
12/10/8 kW of Inverter power with G100/2 export limitation is what is needed.
Customers being able to export âsellâ back to the grid reduces the payback on systems significantly.
Even on bigger grid tied ESS we will now only be able to install as much as the export allows. Thus reducing the number of units installed and sold.
This decision makes Victron a very difficult sell in the UK grid tied market.
Is G100/2 really that much more work than G100/1 ?
Hi Guy, Appreciate the reply. Please see my reply to Vincent below. Hoping we can get Victron to change there stance on this
If you need a solution for g100 in the UK please reach out to www.offgrdpro.co.uk. They have a g100 solution for victron that has been through witness testing and allows for compliance - albeit with extra cost.
For Victron this is chicken and egg I guess. No surprise the installs are low as the product isnât compliant. 48/5000 doesnât give the ability to give whole of house protection as it doesnât support 100amp passthrough .
Very disappointing to read that Victron is not going to update their firmware for G100/2. Arenât they likely to get similar requirements in other countries too, so functionality like this will need to be added eventually?
Has anyone used node-red to fill in the missing bits of G100/2? Given that the G100/1 stuff works (or at least has a certificate), the bit that is missing is the state machine for repeated excursions. Node-red should be able to handle that (I think), which should make a compliant system.
There is a difficulty in that the standard fast-track process with SGI3 only allows for type-certification, not compliance by other means, so one would have to do the next grade of application using Form A2-3 (âLess than 50kWâ) on p7 of https://connections.nationalgrid.co.uk/downloads/24747
If no-one has done the node-red work for this, Iâll have a go. But it seems reasonably likely that someone has already done, or at least started, this work.
This would be much better implemented in the MPII firmware, but if Victron arenât going to do it then weâll have to make-do. Of course if they opened up the firmware code we could help fix it there, which would be a better solution.
That should be http://www.offgridpro.co.uk
Depends on the house. The 50A passthrough is sufficient here. The only thing thatâs not on the backup is the EV charger (because itâs a big load and charging one battery from another doesnât usually make much sense).
By means of update we completed the coding on our Victron g100 unit a couple of weeks ago and submitted to ena for assessment. Itâs our first time through this process so no idea how long this is going to take. ( we have submitted all our test case for the requirements )
The solution works exclusively with Victron and if approved will be a low cost option ( when compared to other standalone g100 products) to achieve g100 compliance
Hello @jonstret, any updates on the G100/2, got a job at the moment which Victron should be ideal for, but need close to zero export from the multiplus and DNO wants G100/2 (becoming more common in my area it seems).
You have some nice pictures on here, assume they are off-grid rather than grid-tied due to the size, or just good grid connections?
CheersâŚ
Thanks,
SimonâŚ
Hi Jon, could you expand a bit on what your solution consists of? I looked on your website, but could not find any details, just of lot of pictures of snazzy complete installs in expensive houses which made it all look very high-end.
I failed to find any info on individual products, like a Victron G100 standalone device. Size, cost, topology of installation, specs? Perhaps there is a secret URL with details in there somewhere?
In general my experience of websites that starts with glossy pics and âcontact us for a consultationâ with no mention of any actual prices, means one canât afford whatever it is they are selling 
Glad to hear that at least there will (assuming you pass) be a solution. My experience has been that in fact DNOs are still accepting the G/100 cert at least for small systems, but obviously thatâs not something most people want to rely on, and actually complying with G100/2 is obviously a good thing.

In the UK dont you find it odd you can legally connect(via a sparky) a 10kw shower to the grid but connecting a one way (zero export) 5kw battery charging system has to be approved by DNO! For example why cant a Victron skylla 50a charger be your only connection to the grid ( i am assuming here as its a charger its one way with no reverse export possible unless defective). Plus installing a Victron Isolation transformer (used widely on boats-ok mainly to stop corrosion) and your own earthing system would ,it would seem , makes it impossible,in my simple view, to pass power to the grid). I am ignoring uk building regs here for the moment as I just want to see some replies from the experts. Last resort I guess would be âoff gridâ and a 10kw(++ better depending on power usage) then the g100 will never (never say never!) apply. I must point out I come from IT/UPS background so I am most likely talking hogwash - please feel free to reply.
Indeed, I have attempted to get some clarity from the DNO on this, but they seem very unkeen to commit to anything, seems that it has the potential rather than it can. We connect boats all the time to the grid and never do a G98/99 for that. It actually takes a fair bit of effort to grid tie a victron inverter, install ESS etcâŚ
Looks like its now approved on the ENA register⌠This is a game changer for us TBHâŚ
CheersâŚ
Our g100 control system just passed the ena tests. If you go to the connect direct website and search standalone g100 units you will see the offgrid pro solution is compliant
We are finalising pricing and expect to have units available to ship in 4-6 weeks
If you email the office info@offgridpro.co.uk we can keep you up to date

Not really - the shower cannot send any power backwards and electrocute operatives - itâs not a generator. A battery or an inverter is a generator and the G** regs apply to generators. i.e it not due to power, itâs due to direction. OK, they can be configured to be input only, and yes maybe the regs should only apply if you are going to turn export on, but not many people want to install PV or batteries without the ability to export, and it might get turned on some time after the install, so I can see why the DNO has done it this way.
Having different requirements for every country is the main issue here. Manufacturers want to do this work once, not 26 times, just for Europe.
Yes you are correct BUT a pure battery charger(not an hybrid inverter) is just like a shower - one way(direction)- and there are such chargers sold by Victron (e.g. Skylla) and many other manufacturers compatible with the various battery voltages. IE. the Multiplus/Quattros would not be connected to the Grid at all.
And there are many of us who donât want to give the grid anything. Hence the comments on this forum about people going âoff gridâ - then you are only subject to Building Regs.
I take your point about different requirements per country/ manufacturing costs but its not the manufacturers,in my opinion, that need to supply the âexport limitersâ its the DNOâs in each country. Even within the UK DNOâs differ on how/what/why they will approve even with the central database. Its is very frustrating.
