    Home 3 = £630 inc VAT. £525 EX VAT. Add £30 postage = £555 (€650)

    Home 3 Pro = £690 in VAT. £575 EX VAT. Add £30 postage = £605 (€709)

    UK VAT is 20%. You need to get a VAT free quote, hence the above figures. There is a possibility that you will be charged 23% Irish VAT, but this hasn't been the case for me on 2 orders spaced a year and a half apart.

    Hypervolt is also solar suitable.

    RECI fees are a magical mystery. Nobody knows what they will charge.

    Reci were the safety supervisory body but no longer. It's Safe Energy Ireland or something now.

    A REC or registered electrical contractor would be charging anywhere from 35-50 per hour.

    Materials cost would about €40 for the isolator, €35 ish for the Rcbo, €60-70 for the surge protection if required and assuming your board has space, more if not. Your main fuse would need to be changed for an mcb if that's what's in the board, about 10 quid for that. Cable €3-5 per meter depending on cable type. Cert and test record sheet circa €20. Another €15\20 for bits and pieces.

    The Rec is obliged to test all the rcd's, check the main incoming cable and fault loop impedance. These results must be recorded on the test record sheet.

    They must check all terminals in your board are torqued correctly and that all blanking pieces are in place. Check for an earth rod, and check that gas/water/sink is bonded as appropriate.

    All these tests must be completed before any work is carried out.

    See this setup - https://www.youtube.com/watch?v=W8i_jgvjqkc

    Would this allow me charge at 7kw per hour with the right cabling run to the box?



  • Registered Users, Registered Users 2 Posts: 4,422 ✭✭✭...Ghost...


    Yes. That would work. It would be a dumb charger of course.

    You will still need to upgrade the RCBO and cable regardless.

    A good commando and isolator socket will be about €100.

    Tesla granny charger is €200.

    Tesla Commando adaptor €50.

    Total excluding installation €350.

    That's €300 less than the Hypervolt. I'd personally pay the extra for the functionality of the smart charger. I wouldn't want to leave a granny charger plugged into a socket the whole time, because it is easily stolen. Completely up to whoever is spending the doh.

    so could be

    Tesla granny charger €200.

    Tesla Commando adaptor €50.

    commando socket and idolator €100.

    RCBO €50

    Run fresh cabling Cabling €50 (less than 2 meter run from fuse board)

    €450 + electricians cost, maybe €150

    €600 total perhaps.

    IIRC you're in a rented house and the LL wants everything removed when you go, and I'm assuming your LL won't reimburse you for any electrical upgrades that might be required for a fixed 7kW install, such as potential upgrading meter tails/earthing/bonding/etc. Do you know if the house would require much upgrading? Using the SEAI Grant info as an example:

    "Yes, it is recommended to get an electrical survey of your home done before finally deciding on the EV and home charger combination you are finally going to purchase. You should investigate what the power in kilowatts (kW) requirement of the on-board AC to DC charger for single phase 230 Volt supply will be. The electrician will examine the quality of your home wiring with respect to the current safe electrical standards and the proposed power demand from your EV.

    He/she may recommend upgrading the wiring before installing your charger unit. Typically the upgrades may include one or all of these:

    • Improving the Earthing connection.
    • Increasing the wire size of the connection between your fuse board and your electricity meter. You can read more about this in our blog Meter Tails in a Domestic Setting
    • Improving the electrical bonding between the metal pipes in your house.

    Should these upgrades be required, please note that these costs are not eligible for grant support."


    IMO in a rented house your aim is to spend as little as possible and not spend lots of money you won't get back. Personally if the granny charger is fulfilling your needs adequately for the last 4 years I'd stick with it, unless you're upgrading to a newer car that will take the 7kW then fair enough. The 32A commando set-up you posted would work, but the electrician may still want to do any required upgrades before installing the 32A socket.

    Also, it's hard to see in the small photos but I notice in one of your photos you appear to be hanging the granny charger from the socket by the plug and cable, this is not good for them and can cause failure.

    The below is a general 'signature' and not part of any post:

    FYI, if you move to a 'smart' meter electricity plan, you CAN'T move back to a non-smart plan.

    You don't have to take a 'smart' meter if you don't want one, opt-out is available.

    Buy drinks in 3L or bigger plastic bottles or glass bottles or cartons to avoid the DRS fee.

    Thanks. But without an actual EV charger wired in, you are limited to circa 2.2kw entering the car? That's just what I am wondering - how would one go about getting power into an EV without a charger unit tied back to the board? Or is there an alternative of running 4 or 6mm cable from the board and tying it into a more basic dumb socket that just feeds the car at the 7kw?

    Thank you!!

    Yep, he wants the setup back to what it was when I leave - with just the external socket. fair enough, that's perfectly fine.

    regarding the meter tails and all this - could be a problem. Like if it involves work between fuse box and meter box, I just wont bother. My only focus up to now was between fuse box and charge point.

    I am getting a bigger battery car....... so the 2kw charging per hour is not great, but if its hardship or overly costly to upgrade, I will just have to continue with the granny charger and do with it 😔

    The crux of this whole thing is living in a rented house (for my sins), and as you say, my aim is to spend as little as possible with the least amount of changes. Landlord is good enough to allow me to do this in the first place but he wants minimal disruption. if there are any overly complicated or costly upgrades needed , I will just leave it off entirely.

    House was built in 2004/2005 if that makes any difference to meter tails or upgrade work etc

    regarding the photo, from day one, I installed a hook and I actually have the main weight of the granny charger hanging off the hook, so this takes all the weight off the plug :)

    I have an electrician coming for a free survey, before he comes, I am just educating myself.

    I guess I can present the electrician with 3 options and see what happens

    • 7.2 Kw charger option
    • 3.6kw charger option
    • Commando and Tesla charger option

    Ye, wasn't sure I could see something holding the granny charger or not, sounds like you've a good setup for it.

    I think at this stage you'll just have to wait and see what the electrician says and then decide where to go from there. I think most of the issues that may arise have been mentioned in the last few pages. Hopefully it'll turn out to not need any major upgrades and be a bog standard install. 👍️

    I hope it will be relatively straight forward. New RCBO, isolator, new 2 metre cable run from fuse board to charger and then install 7.2 charger. Job done. But will see…..

    I don't need anything fancy. Just a really simple setup - Plug it in, set timer in car to start at 11pm and end at 8am. Nothing else needed.

    here is my high tech solution to take the weight off the plug 😀😀

  • Registered Users, Registered Users 2 Posts: 6,322 ✭✭✭obi604


    Had a chat with electrician, will probably go down the install a 7.2kw ev charger route.


    Can anyone recommend a decent 7.2 kw EV charger that qualifies for the SEAI grant that is not too expensive? don't need solar etc just basic charging.

    Something in the 400 or 500 Euro bracket. Or are all of them just simply more costly than this (if you want to get something half decent)

    Zappis seem to have a good rep, but they are fairly expensive



  • Registered Users, Registered Users 2 Posts: 167 ✭✭Fastpud


    I recently up graded my car from a 40kw Leaf to 65kw Kona and now the home charger can’t refill to car in a single night.

    IMG_1377.jpeg

    I have one of the original 3.6kw ESB chargers. Does any one know if they are upgradeable ( I’m an electrician so the electrical side ie breaker, cable, internal contactor etc) is easy but don’t know anything about protocols, ie how will the unit know it can deliver 7kw)

    If it was easy to configure it would work out a lot cheaper than getting a new one.



  • Registered Users, Registered Users 2 Posts: 34,359 ✭✭✭✭listermint




  • Registered Users, Registered Users 2 Posts: 167 ✭✭Fastpud


    I was asking if it possible to up grade the existing charger rather than replace it. Yes it is easy to get a new one but if the existing one could easily be modified to deliver 7kw it might make more sense.



  • Posts: 2,704 [Deleted User]


    I don't have any experience with these charge points but many have a dial or dip switches internally to adjust output. Worth opening up for a look anyway.



  • Registered Users, Registered Users 2 Posts: 6,322 ✭✭✭obi604


    I like the compactness or the wallbox chargers. Nice and discreet.

    are they any good?

    seems to be a choice between wallbox max and plus, does not seem to be much difference in spec



  • Registered Users, Registered Users 2 Posts: 4,422 ✭✭✭...Ghost...


    They can be upgraded AFAIK. I think @unkel might be the man to fill you in on that.

    Zappi problems are common enough. Wallbox would be a better choice, but I think there is a thread in here with people reporting issues with them failing. Check the first and second page of the forum. My SIL has a wallbox and I haven't heard of any issues. I also bought a no name 7kW charger on ebay for the inlaws 6 years ago. No issue. Pick what you think is the best solution.

    Yeah. Just located a thread on wallbox with a good few reports of WiFi/connection issues.



  • Registered Users, Registered Users 2 Posts: 909 ✭✭✭MICKEYG


    Hi all, looking to get an EV charger that is future proofed for Solar PV and home battery.

    I have been told Zappi is the way to go. Would all agree?

    Also, any recommendations for installers. There seem to be a huge number of companies out there but looking for someone I can trust so that if any issues there is no quibble.



  • Registered Users, Registered Users 2 Posts: 24,262 ✭✭✭✭ted1


    i still have yet to see any advantage with a “future proofed EV charger”

    just export/sell your excess during the day and charge at a lower rate during the night.


    if you are worried about your carbon footprint , rest assured the stuff you export will be used by someone.



  • Moderators, Sports Moderators Posts: 19,829 Mod ✭✭✭✭slave1


    That ESB unit can be flashed alright but it's years since I seen to post so can't remember. I'd say Mr ESB only put in a 16amp cable though so that will need to be changed to 32amp, going by your picture if the power supply is that white cable on the left it almost looks like 2.5sq?



  • Registered Users, Registered Users 2 Posts: 909 ✭✭✭MICKEYG


    I get that but I am thinking of the battery. If there is a power cut I could charge the car from the battery. Low risk I know but still better to have it than not have it.



  • Registered Users, Registered Users 2 Posts: 4,422 ✭✭✭...Ghost...


    The poster asking is @Fastpud

    That’s not my charger. Yeah, I remember now they needed to be flashed.

    The cable is definitely 2.5mm^2 and should be armoured because it’s external. It also should have been 4mm^2. Very lazy install on top of using the wrong materials. That’s what we pay the professionals for eh? 😂

  • Moderators, Sports Moderators Posts: 19,829 Mod ✭✭✭✭slave1


    2.5mm can handle the power fine I'd say but absolutely should have been in trunking, anyhow what's done is done and the irony of being under the ESB umbrella

    @Fastpud you could always just go for a fresh install with new charge point, but as a recipient of the free charger can you avail of the current grant?



  • Registered Users, Registered Users 2 Posts: 24,262 ✭✭✭✭ted1


    What speed can the battery discharge , and can the battery discharge during a power cut?

    You are not allowed use a battery and be connected to the grid if the grid is down. Most installers won’t deviate from this.



  • Moderators, Sports Moderators Posts: 19,829 Mod ✭✭✭✭slave1


    Most inverters have an EPS output, even a double socket hooked up to this would allow Granny charging (assuming Inverter output capable)

    In that case it makes no different what charger he has. As he won’t be using it..
