Not sure I'd go right to 64A, might not be much to spare for the house and that fuse has to be replaced by the ESB, it can't just be reset
But yes, if you're taking the cable from the meter box then you could just take 2 cables each wjtb a dedicated breaker
You could do a similar setup to mine and have 2 Zappis witb a group limit, or have a Zappi monitoring the other charger. You could configure the group limit to something like 50A, so you'll still get around 4kW even if the other charger is pulling the full 7kW, and still have plenty leftover for the house
With 2 Zappis they have more advanced options for load balancing, they can divide the available power equally or one can be given priority over the other to give a guaranteed amount of power to one
That's exactly the sort of thing I had in mind.
I didnt think you'd want an overall limit of 32A. On another thread you were discussing having 11kW and increasing fuses etc. amazing_raisin's setup is two charge points but limited to a max of 32A between the two.
I would have expected that your ideal is to have two load sensing charge points and set the grid limit, not the charge point limit, and then you can theoretically charge both cars at 32A each, assuming your main fuse is 80A+.
That's the dream alright, throw in V2G from the cars to keep you going on cloudy days
Yes solar would also be on the roadmap too.
Would love to have two tethered chargers at home, solar and storage so that we're load balancing and only consuming night time electricity to charge the car/s.
If you are looking at Zappi then I assume you are looking at solar, could be an idea to wait until doing your final solar bartering and get the Charge Point install "thrown in"
Yeah they're not cheap unfortunately, I got mine direct from MyEnergi before Brexit happened so might have saved a few euros there. Still cost the guts of €1k
I also got the hub and a Harvi which added some cost. I'd recommend getting the hub as it allows you to update the firmware easily. Mine needed a firmware update to get the load balancing working properly
If you EO is new enough, it might be able to work with their load management module. Mine is from early 2018 and predates that feature, so it didn't have the wiring ports for the load balancer. It might be a cheaper option than the Zappi if going untethered. I wanted a tethered charger and the Zappi has much nicer cable management IMO
Thanks for the details and photos. That's exactly the sort of thing I had in mind.
We likely wont be moved till Jan/Feb at this stage but I havent claimed the grant on her Ioniq or (obviously) at the new place, so I will get the EO mini with the grant and then buy the Zappi and get the installer to put in a similar setup - unless of course software enhancements render it moot in the interim.
Good to see experience of someone who has 2 EVs and 2 chargers. We live in rural meath and are moving to another address in rural meath, where every "nip to the shops" is a 30km+ round trip. We'll need 2 chargers if we are to move to 2+ EVs.
Reading your comment, I think two Zappi would be the best setup but would have to price it. Seems to be between 800-1k per charger net of the grant.

I bought the chargers myself, so just got an electrician to install it. I'd recommend the crowd who did the Zappi addition, will PM details.
I already had the EO Mini with the isolator, so the labour cost of adding the Zappi was only 3 hours, €135
Can't remember how much the original install was, but it pretty much used up the €600 grant. Had to come 12 metres from the CU as taking from the meter box wasn't allowed at the time. Hopefully you can take from the meter and it'll be much simpler and cheaper
Here's some pictures of the setup
You can see the CT clamp in the last picture around the live input to both chargers (bit tricky with the wires bundled up but you get the idea)
That CT is wired back to CT2 input on the Zappi which is set with a 32A limit
It's worth saying that if you got 2 Zappis then they can use their internal CTs to monitor current and you won't need the external CT
I think EO and Wallbox can also do the same, but they might need addon modules. Possibly still cheaper than a Zappi though, they're not exactly cheap
Who did that setup for you and how much did it cost?
When we move house I intend to have 2 EVs (and possibly move my van to EV in future) so would like that sort of setup
2 EVs here (Leaf & ID.4) with 2 chargers, EO Mini & Zappi
Setup is that they share a 40A breaker and the Zappi monitors the load on that circuit using a CT clamp
Zappi has a 32A limit set and the Leaf only charges at 16A. So if both cars are charging the Zappi will reduce to 16A to stay within the limit.
At other times the Zappi will run up to 32A if available
FYI, the latest EO Mini has load sharing capability via the addon ALM module. Mine is the older version which doesn't support that and the original plan had been to replace the Leaf and EO Mini with the ID.4 and Zappi. Then we kept the Leaf and needed 2 chargers
Also to be fair, the number of instances where we needed to charge both cars has so far been 2 times. Other times we've only needed to charge 1 at a time. We'll see what winter brings with more potential consumption and more charging needed
We've had 2 EVs for a number of years now, it's pretty rare that we ever use a full battery on both cars in one day, and when we do it's even more unlikely that both cars will need a full charge the next day. With that in mind we just have one charger and a coiled cable that can reach both cars. Majority of the time we only need to plug in one car, sometimes we'll put one on for a short while before switching to make sure we're covered. Majority of the charging therefore happens during night rate, but I'm not going to grumble if every so often we spend an extra €1 to make sure a day is covered.
Many cars have the option to lower charging speed so you could lower the speed on the one which needs less charge. With load sharing the car that starts first will get maximum power, the car that starts second will get what's left, so by timing start times you can ensure one car will get priority.
If you are dropping to 16amp charging you really have to question that, you are losing 7.4kW into one car which you need to think about. Remember you can get 2.2kW from a 3pin socket, is the gain to 3.6kW really worth it at the sacrifice of losing 7.4kW charging capability?
I seen a charger bollard on adverts that has 2 sockets , only 3.6 kw each, but it would allow 32 kWh into each car @ night rate electricity prices.
Yeah thats what I was thinking. If you have 2 cars and you charge overnight to avail of the cheap rate, you can't charge both during the night.
You can load share 2 chargers, if you set timers right one car will get priority. Actual suitability depends on cars and miles covered per day. You won't get the grant for second charger so most granny charge second car will less needs. If you have night rate you need to set timers in car and granny charging only puts in about 2kW per hour, so you may get limited energy overnight.
Yep, 2 EV for a few years, have single charger and external 3pin socket. Thought was, the 3pin could be used if charger in use, turns out we’ve never once had a clash, just a quick chat as to what car needs charging is all.
Anyone on here got 2 EV/PHEV in the household?
Wondering how you handle charging?
Do you have 2 chargers? Or do they share a charger?
Having faffed about with a charger in the rain, even this small cover will help. We just need to make sure it never rains and is windy on the same day!
Those look hilariously useless. They won’t even do anything for the units, never mind the users.
So canopies for the units not for the users? It's a start I suppose, maybe eCar could consider it...in about 10 years time....
As an EV driver I need to use the public charging network from time to time. West Dublin is a disaster with queues at all 50kW+ chargers on a Sunday morning. One charger had 4 cars, one charging. Now Blanchardstown was out if action for weeks due to upgrades, but even then all chargers near Dublin airport at full all day with new EV Taxis filling up. As an EV owner I advise others to not buy an EV until public charging improves and there is no sign of that happening as ratio of chargers to cars is getting worse. We need 3 times as many 50kW+ chargers now, far more for the needs of future years. NI is a total disaster with 50kW chargers broken for years, some no CCS. Having to queue for an unknown amount of time, while the car charging is unoccupied, takes the shine off your day and car type decision.
You mean every new car right? 😜
Most popular selling cars for the past few years have been mid size SUVs, Nissan quashqai, Hyundai Tucson, Kia Sportage and VW Tiguan all top the lists of cars sold
Since EVs are new to most brand, they're focusing on the most popular and profitable segments where they know they'll sell
As for the chunky wheels, I guess that's just a way of upselling people to a more expensive car
It is for efficiency. There are ways of changing that. Tesla aero are removable covers for example.
I think there's way too much emphasis on the charging network from non EV drivers. People are used to having to refuel their cars on the road all the time. Home charging removes that requirement for over 90% of trips for most people. And the supercharging network is coming along nicely for.longer trips 😉
Department of Transport, Transport Infrastructure Ireland, National Transport Authority, Department of Environment, Climate Action Plan, Climate Action Fund, state-owned ESB. Setting up OLEV.
Option 1. Do very little and set up OZEV in 2030.
Option 2. Mass. Is there anything to be said for saying another mass.
What's with the chunky wheels and block shape of every new ecar? It looks so unappealing.
What about DoT? They are those in a very bad light. What were their policies to encourage the take up so far? I feel it is very late for such a focus group. At this stage they should ask the question "How are our policies working?". Anyway much has been discussed already but with the right policies it wouldn't matter if ecars are lousy or not. The thing is gov couldn't care less bar some press releases and the results are visible. Iceland has more DC chargers than us and probably Reykjavik will have a metro before Dublin.
So this evening I took part in a Department of Transport focus group on the subject of EV's. The primary focus was on how to get more people driving EV's.
Suffice to say the overarching feeling among the participants was that the network is simply nowhere near where it needs to be to encourage the next generation of EV drivers to switch to EV's.....
eCars didn't come out of it looking too well.....
That looks interesting.
Website is very confusing and I cannot see an option to see the prices with the larger battery pack
