We're starting a big renovation soon (bungalow conversion, will include full re-wire). Want facility to charge two EVs, and utilise power from PV panels.

I've narrowed it down to Myenergi Zappi after 10min research online. Looks like we will need two units.

At this stage I want to make sure I get the right supply in the the right place.

Any other suggestions?
The Zappi is great if you have solar panels and also has the ability to load balance between multiple Zappi's and set a maximum total grid import load which can help prevent you blowing your main house fuse. Two chargers running at 32A does not leave a lot of headroom for other high power devices (electric shower, cooker, heat pump .... ) so IMO this feature is a must if you have more than one charger.
This is exactly what I'm looking at doing. I gather you'd have to limit the combined import capacity to 7.4kW to keep the DNO happy unless they give approval for more. I'm fitting 3 phase so will contemplate whether its worth fitting a pair of 22kW's which could charge at 11kW each simultaneously to cover all bases. It wouldn't be used very often but there's something handy about being able to charge two cars during a single off-peak window.

I've got solar panels/battery coming end of September.
I need to get a charger for a BMW hybrid now (EV incoming next yearQ1/2) so I have read a few pages and Zappi sounds good to me, are there any other home chargers I should consider?

I have just switched to Octopus Energy too although my smart meter is not compatible so waiting for that to be installed then move to the Go tariff for lower cost charging.. (I am learning).

I actually ordered an Andersen as recommended by my local Porsche Centre and I like the Simpson Partners but if there is an option to charge the vehicle from Solar then I am keen to exploit that - even if its only in the spring/summer months..

Thanks

I've just ordered an Ohme Home Pro after doing my research online.

ProEV (whom Ohme put me in touch with) are currently doing a standard installation of the charger for £899 (rather than £949) for anyone looking.

Loads of people round here have Zappis and chatting to a few of them they seem happy.

Also very few people think that you would actually need 2 charges unless both of you are doing 200 miles a day each

Thanks will have a moan to Octopus about them.

Had to send the install team back as used under rated wire around the meter.. So might be why they never provided them

Given the options of connecting your EV charger off the meter cabinet (with Henley blocks and split tails) or running a cable into the house to connect to the CU, are there any real disadvantages in the meter option? It avoids drilling into the house and running a cable but are there any potential problems?

Thank you.

You don't really "need" a charger at home as the network is so good according to some on here (total balls).

Having two chargers for us would not be about charging the cars at the same time, it's just more convenient, no shuffling cars about or making sure the right car is in the right spot etc.

I’ve been quoted £1518 to be supply and install a 7kw Zappi 2.1, seems expensive to me, anyone know if this is a fair price? Installation is very straightforward, new home and box will be in the garage 5m from the consumer unit, no issues at all.

Everyone knew I would be along to 'answer' this one.

The theory is that the meter cupboard is for the use of the DNO and the metering company. The consumer isn't supposed to haver any equipment in there. It only really becomes a problem when the DNO needs to add/change something and it doesn't fit - that then becomes the householder's problem.

It isn't (shouldn't be) just a pair of Henley blocks either. You would need some form of cable protection for the cable that runs to the EVSE.
So, we are adding Henley blocks plus a small consumer unit. You really want an isolator after the meter for 'serviceability' reasons - but the DNO will add that for you - it is permitted - but then becomes the householder's propery.

Many people will have installs done like this - but in my opinion, it isn't the right answer.

ETA: The guys from eFIXX have looked at this - the answer is no. https://youtu.be/864pJSfAuOY

I paid about that in June.

Zappi 7Kw tethered in white £800 (new one with the wifi)
Harvi (required to throttle zappi on peak load) £60
Installation £750 - this included a lot:
(1) Add mains switch after meter and before main CU
(2) Secondary CU in garage and re-adjust breakers in main CU.
(3) Re-route existing cabling in garage to point to new CU
(4) New armoured cable about 5M
(5) Install zappi and connect to harvi

2 guys all day - absolutely brilliant kept my OCD in check.
still no BEV yet.

Might be worth filling in the form from Octopus. You do the survey on the form and they give you the price. Says from £1159. I paid the price they quoted on the Ohme I have.

Sounds about £200-300 too much from what I have looked at recently.

Just use RCBOs - every circuit is then having its own protection.

I know the Zappi can be had for just over £700, they’re a no mention of a Havri, simply £1256 for the Zappi an mcb and some armoured cable, just under £300 labour. I’ll wait for further quotes, my house is only 4 years old and they commented that the job is straightforward. Just like solar, I think the EV market attracts the cowboys.

yep there are certainly some cowboys.
one guy came round to quote and I new straight away he was trying to figure out how much he could get away with. Gave me a whole lot of technical talk which was bull. Little did he know my degree was Elec Eng.
the guys that did my installation were totally different - came with all the EV charger testing equipment, proper labelling and what is always a good sign - a henry hoover.

I've been recommended (and getting fitted next week) the Zappi because I intend to also get solar and batteries.

Be interested to know what you get quoted and for what.
