Thanks mate, will call them up!

Just out of interest would you know what the total installation cost was?

EVSE installation cost will depend on what's required. If they have to install MCBs etc at your switchboard and run wiring, that obviously has an effect. If it's simply a 'fix and commission' as mine was* (took about an hour) it's a bit over $2k. They'll be more than happy to quote to your individual requirements.

* I had an electrician friend upgrade my switchboard and do the endpoint switch wiring. I was the sucker who actually crawled under the house to run the cabling from the back to the front, but that effort saved a bit of money.

Their install was a bit spicy. Distance from switchboard, access and condition of existing wiring were all a factor in this case.

The EVNEX website has a standard fee for certain conditions - start there, I reckon. From memory they do an on-site quote for the work if there's complications beyond what's listed there.

They were happy to do a desktop quote on mine. It was a relatively simple install in a new build going from the panel in the garage to the opposite corner via the roof space and wall cavity that had no insulation inside. If you want a quote include photos of your switchboard and fuses and the full cable route listing anything that could impede them.

All up I paid about $4000 for a pair of boxes in a back to back install when their standard price was about $2250 each.

It was expensive but I really haven't had to even think about them since then and they just do exactly what I need of them both.

Just got an email from evnex about them launching a new evnex e2 charger with the announcement at 12pm 18/4. Not got much more to go on that but they are running tag lines about carbon and your impact. So I'd guess it's either smart features tied to some form of data to selectively charge or a V2H/G capable box.

Full text from the email:

Your EV can do better
Do you know the real environmental cost of driving your EV? Or how you can reduce it?

Join us for a virtual launch event where we'll unveil groundbreaking EV charging features that help you make choices that lower your impact and do the right thing when it comes to powering your vehicle.

Just watched the evnex announcement and it's not all that bigger deal, it's just a replacement box that adds a button to override the charge settings and is thinner in more colours. It's from $1395 for the unit only and they seem to have removed their standard install pricing.

Strangest decision is they have removed the option for a type 2 socket and all chargers are now tethered with your choice of cable.

Biggest change sounds like it's coming to old chargers to and they will tell you the carbon footprint of charging your vehicle and potentially your entire home. A nice free upgrade but probably nit that significant to most users.

Awesome! Then they will be able to cross link it to your social credit score! (/s)

My questions relate to V2L adapters/cables (which I thought connects better to this thread than the general EV one)…

My partner’s getting a car that has V2L capabilities; given we had our emergency generator stolen out of the garage a few years back, I’m happy to invest in a V2L adapter to add to our emergency kit (plus perhaps make an espresso somewhere in the wops!). The OEM adapter is $300, which I’m happy to pay but I also thought I’d look at what else may be available, given that’s a short cable with a single plug (I get I can use a multi box).

Some members of the NZ MG FB group have gone with adapters from TM; I’m assuming they’re like this one (if they had one for MG/AU plug in stock!), but I’m a bit dubious about buying such an item from there - what’s the legal status of using such a product, and would it likely cause an insurance issue if something went wrong when using it (even if it wasn’t the cause)?

About the only NZ-supplied alternative that I’ve found is this one, produced by an electrician in Akld; it has the advantage of a longer cable (plus uses a multibox): https://www.trademe.co.nz/trade-me-motors/car-parts-accessories/other-accessories/auction-4275582882.htm

Has anyone got experience with non-OEM V2L adapters, or care to comment on any options including those above? Or am I best/safest to just stick to the OEM product?

Thanks in advance.

One of my colleagues bought a V2L adapter for his MG off AliExpress. Quality is good and it works well and I think only cost him around $150.

I'd be wary of the V2L adapter you found on AliExpress -- it doesn't look anything like the OEM equipment and (despite vague assurances of various types of safety protection) I see no reason to trust the retailer -- who opened up their AliExpress shop not much more than a month ago. You might receive a factory second, or one which didn't even get quality-assured before an employee of the manufacturer obtained it with a "five finger discount". The retailer's record is easily found on AliExpress: https://www.aliexpress.com/store/feedback-score/1102977113.html?spm=a2g0o.store_pc_home.pcShopHead_2006111269564.2

The manufacturer took me a while to sniff out. The retailer claims the manufacturer is "ERUS". Erus is a reputable Chinse OEM, but https://erus.en.alibaba.com/search/product?SearchText=V2Plus comes up empty. I think the product you found was designed and manufactured by Shenzhen Asia, see https://www.alibaba.com/product-detail/v2l-adapter-cable-ev-v2l-adapter_1600411431739.html. The company page for Shenzhen Asia gives me the impression of a bottom-feeder, not of a top-end manufacturer which Hyundai might rely upon as one of its (many!) OEMs.

Having a plugboard hardwired to a Type2 connector would be a convenience in some applications, e.g. when camping and the lead is long enough that the plugboard would *always* stay dry (e.g. stay inside your tent). The plugboard supplied by Shenzhen Asia is unlikely to be a high-quality one -- and I really doubt the retailer would supply you with an SDOC. I'd be pretty sure there's an SDOC on the 3-plug 10A plugboard from Stanley which somebody (who might be a registered electrician in NZ) has connected to a Type 2 plug; but would this TradeMe retailer offer you a certificate of compliance (https://www.ewrb.govt.nz/assets/documents/forms/WKS-14-electricity-electrical-coc-and-esc.pdf) I rather doubt it, so it's really a matter of caveat emptor -- did they wire it securely enough that, even after it's endured some "normal" abuse by being coiled up and uncoiled somewhat carelessly, it won't overheat? You won't need the certificate unless you're using it in a business context -- and WorkSafe would I'm sure have serious questions of any contractor who was running a powertool outdoors on such a rig. Anyway that TradeMe assembly will limit your power to 10A, whereas the OEM part from Hyundai would accept a 15A plug... not that you're likely to find many appliances in NZ that are fitted with a 15A plug. AFAIK only Tesla has supplied an EVSE into NZ with a 15A plug... so if you went with the Hyundai OEM you could offer a stranded Tesla driver a top-up charge; but if you went with the TradeMe assembly they'd be out of luck... but you could reasonably-safely supply someone with an 8A EVSE an hour or two of top-up charge. (Sourcing 10A for an hour or two might cause the sockets on the cheapo plugboard from Shenzhen Asia to overheat.)

All to say that if I were you I'd pay the premium for the Hyundai part. It'll stow nicely, and you can always fit an extension cord if you want to magnify your electrocution risks slightly by powering equipment that's at some distance from your vehicle. As for powering multiple devices from V2L... that's the sort of thing I am prepared to do at my house whenever the power is cut for more than a day. I run extension leads to power my refrigerator and my fibre modem. I monitor plug temperatures as well as voltage and total loads very very carefully whenever I make a cuppa on my espresso machine. Running the microwave would be an overload. And I'm aware that this is risky; but hey I'm willing to take some chance of tripping over an extension lead in order to avoid the major hassle of having food spoil in my refrigerator or freezer!

A Certificate of Compliance (and I'm pretty sure ESC too) is only relevant to installations. I don't think a vehicle-to-load adapter would constitute an installation, though it could perhaps be assembled into part of one.

Compliance with ASNZS 3112 and by reference ASNZS 3760 would likely be what's necessary for worksites - this is not too dissimilar from the Lifeguards/EPODs manufactured by Jacksons in that respect.

A socket designed to fit multiple types of plugs is basically an automatic failure - they fit no single type properly.

I agree that it's hard to imagine an adapter as an "installation"! However as you say it could be a part of an installation e.g. if you stay at a caravan park which insists on a CoC, and somebody really narky (or very clued-in about electrical safety ;-) notices that you have run a lead from your Hyundai's V2L into your tent. On rare occasions I have been asked for the CoC on my e-NV200 e-motorhome, when checking into a caravan park.

I'm very intrigued by your "automatic failure" comment! In your experience, has a WorkSafe inspector ever issued a fail to a site because it has an AS/NZS 3112-15A socket? I can readily imagine a fail for a site with a CPCS-CCC socket (https://www.wall-switchs.com/8808.html), but has WorkSafe made some public statement that (as of some date) the use of AS/NZS 3112-15A is verboten at the workplace???

And... after a bit more internet research, I discover that what's *really* required at a caravan park is a WoEF I'll now root around in the paperwork I received, a few years ago, from the guy who wired up my e-NV200... but anyway it has to be renewed every four years! Learn something every day! https://www.worksafe.govt.nz/topic-and-industry/energy-safety/electrical-and-gas-safety-requirements-for-caravan-motorhome-and-boating/

Thanks for the posts and advice - useful stuff.

Just a couple of points: this is for an MG, as opposed to a Hyundai. Also, I just gave that AE item as a rough example, not a particular product I was looking to buy. If I was to buy from AE, I’d rather get a specific product that others have reported as decent quality.

Speaking of which - @michaelmurfy, would there be any chance you could ask your colleague as to the specific type (even model/seller) they bought for their MG? Thanks, if feasible.

In the end, I’m happy with a single power point, and can look to get something for better waterproofing if it’s on a short or no cable.
