Zappi charge points

Looking at the manual the grid limit is off by default. Install was done by my usual electrician who wouldn't have had any experience of the zappi so probably wasn't aware of the setting.

He did think it shouldn't have allowed that high of a draw though and was going ringing my energi tomorrow when they open.

What would be a good number to set as the limit? 12 or so?

Yes 12 is plenty, most houses have a 63 amp main fuse, just check you don't have anything lower.

Yeah I've set the scheduling in the car. The main thing I'm wondering though is does it still reduce current to the car on fast mode say if someone turns on the shower for example or does it only do that in eco/eco+ mode? The manual doesn't seem to clear on this.

Eco and Eco+ are really only useful if you have PV,
Grid limit controls your maximum load regardless of what mode you are in.

You can set the grid limit on your Zappi to whatever you want but 17kw seems too high .17kw should be enough to trip the main breaker in most houses.
You can set the grid limit on your Zappi under advanced settings although I would have thought whoever did your install would have done this.
The grid limit works in all modes.
You can also set the timer on the Zappi to charge the car overnight.

Fast mode but only during night rate hours (you can program your Ioniq to only charge during night rate)

Just got the zappi installed this evening.

I have no solar PV or anything, should I just have it in eco mode the whole time so it adjust the draw as other appliances come on? I thought I should have it in fast mode as we don't have any renewables at the mo but we turned on the shower to see what would happen and it didn't seem to reduce the draw to the car when the shower kicked in so full draw in the house was 17kw while the shower was going :eek:

You'd probably void whatever warranty is on the zappi if you did that too I'd imagine.

Possibly, they're just terminal connectors inside (same as the mains connection) and a screwable grommet at the bottom so no damage would be done.

Possibly. And with the latest spate of issues with the Zappi products, that would be a bad idea.

If anyone has any other suggestions to smart charge my car with surplus PV, let me know

I probably could. But I would have to either butcher my own 15m cable or buy a length of 15m cable plus one connector. And that would all add up to silly money. EUR585 for the charger, EUR200 for the cable, then someone to install it...

It would nearly be cheaper just to charge the car at night rate and let my excess go back to the grid for free.

They are tethered only. And come in either 5m or 8m only. I have asked myenergi but they won't make a 15m tethered one for me.

You can buy reels of the same cable, could you replace it yourself?

I think I'd be getting a type 2 socket and bodging it on to the side of the charger.

I was seriously considering building an Open EVSE from a kit. For a lot less money than Zappi, while it can do more. Until I realised you can only make a tethered one. And I don't really feel like chopping up my 15m Type 2 cable

What other alternatives are there? I can't really justify spending €800 + install costs for the Zappi gen 2 (although I could live with having to wait until May)

I'll have significant solar PV production that I will have no use for from about May. I will not divert to water. Diverting to EV would be ideal for me

I heard from Myenergi that the gen 2 zappi now isnt available until may this year.
they seem to be delayed with all their new releases.

I think there have been some problems with the reliability of the Harvi with respect to the current it's reporting to the Zappi. So if the CT clamp is clamped around the main live conductor and the arrow is pointing towards the consumer unit, and it's connected to the Harvi correctly, then it might be related to the Harvi communication issues.
See: Linky.

Proabbly worth contacting myenergi support.

Harvi was doing something similar yesterday. Showing excess going in the wrong direction. Reset a few times and now Harvi is dead. Waiting for support to get back to me.

it gives the current kW usage of the house

I bought an Owl intuition monitor on eBay last week. Does exactly that and you can place the wireless display anywhere. Cost me GBP7 shipped

Zappi installed during the week, pretty nice that it gives the current kW usage of the house. I now know how much energy my heatpump uses

The Hub was meant to start shipping this week but has been delayed due to technical issues, so it could be a couple of weeks before the app is out.

I had a zappi installed over a year ago. Same as yours it reads Kwhrs on ‘green’ when I have no renewable source and nothing on grid.

I’ve been calling the well known installer since before Xmas and have only received promises.

I swapped the ct connection at the harvi terminals, no change, swapped direction of CT’s, no change even relocated CT’s and harvi closer to meter. No change. I have also tried everything in the zappi settings.

Fed up with it now and it’s annoying me as I can’t use the timer to charge until it’s sorted.

The over recording of the energy sent to the car in the historical log is a known fault in the earlier firmware versions of the Zappi.

Could it be reading how much the house draws rather then the charger

I don't think so, its a 3 bed mid terrace so it can be drawing that much in less than a month. I have to send some information to zappi and the electrician says he'll come you to look at it at some point.

12kWh is enough to power an average house for a year or nearly 80k km of driving!
Looks to me like there is something wrong with your chargers as opposed to your installation.

If you are having trouble contacting your installer you should contact Myenergi directly. They are usually good to reply.

I have attached my log for February for comparison

I've started a thread on home attached battery storage (as opposed to installing a smart charger) for anyone interested:

daheff

question though- are you seeing astronomical electricity bills? If so, something is badly wrong. If not, I'd be inclined to think that the unit isnt a new one.

unkel wrote: »

These issues don't exactly inspire confidence in the Zappi

I think, in the absence of affordable V2H / V2G solutions in the medium term, I will just keep my dumb 7kW charger and go ahead with the cheapest possible AC coupled home battery storage system in the next few months

Tbh my well known installer knew very little beyond getting the unit installed, he even convinced me that I needed 2 CT clamps on the main live tail coming into the house which l knew was wrong.

Saying that, what the guys are describing above looks like there maybe something wrong with the unit itself.
