Zappi charge points

Jeditraining1

Anyone know who is the wholesaler for Zappi chargers in the Republic of Ireland? I'm more so looking for information than to buy one.

I have zappi charger for last 1.5yrs and it has been working perfect with my Hyundai Kona. Yesterday evening when I plugged it in no handshake as if the charger not communicating with the car. I powered down the charger and then tried it again but no luck.

I plugged in the granny cable and handshake and charging straight away.

:P I guessed as much when I read back just now and saw the unit you were looking at comes with a Harvi. I agree it is a bit pricey especially since I am on a new install so don't really need a Harvi unlike you who would rather not run another cable to the charger. The v1 was 600 new. The Harvi is ~100.

My CU is actually ancient and inside is a mess. The PV installers actually got the CT clamps wrong the first time and it was painful to fix it. No room to work. And it has a slightly dodgy trip switch. I might take the opportunity to get a new CU installed.

PS: I think he is wrong about the 8ft though. I researched and Zappi1 came with 5m and 8m options only. No 8ft option.

I thought he may be wrong with the 8 foot cable but it does look kinda short in the pic.

Go into the Eddi Menu and look at the CT Config menu and the Linked Devices menu. You do not need to worry about locating the physical CT Clamps - just remove them for now from configuration

PS: Just checked my fusebox and there isn't room for any more RCBOs. Is that a requirement to get a new ring off the fusebox? I believe v1 doesn't come with its own RCD?

You could simply have an RCBO in it's own enclosure, separate from the existing panel. Also, new regulations now require an external AC Disconnect switch beside the outdoor unit.

While Zappi v2's are getting firmware updates, Zappi v1's are not following to the same extent. If you plan to use it with Solar PV excess, it might be best to bit the bullet and get a tethered v2. The cable is 5m. A cable will get dirty on the ground, so tethered is the way to go, rather than curling up a dirty cable and putting it in the boot

The Zappi v1 I am looking at is tethered with an 8ft Type2 lead. So the Type2 will work but I am wondering if the 8ft might be too short for where I want to put the charger.

I understand about the Sparks and the paperwork. Was just confirming there is no requirement for a new unit.
Thanks.

1. Yes I was looking at the same unit. It’s a bit pricey at €400 in my opinion, especially with the short cable. You need 5m at least.

2. Deffo not. No invoices or anything.

3. Yes it will need a 40a RCBO to be placed in the CU. But talk to your sparks. There may be another way.

So it depends on whether you already have 2 x CT's (or if the required two can be connected directly into the Eddi). If so, then the Zappi will learn everything from the Eddi, and the Zappi just needs it's electricity mains cable

Silly question. Assume Zappi is compatible with a Tesla. I am getting a Type 2 cable and Chademo with the car. Do I ask for tethered or untethered? Will a tethered Zappi v1 even work?
Also, do you need to buy a new charger to claim the SEAI grant? Or will a second hand one do?

1. Any charger works with any car. It’s the cable for that decides what car it’s limited to. Type 2 is what you need for Tesla. The chademo adapter with the car is for eCars fast chargers. You can get 47kw Charging with it but obviously by paying the ESB fees. You won’t use this at home.

2. Tethered or untethered is a personal requirement. For untethered, Some don’t like taking the cables out of the boot and connecting at home. Takes 30 seconds but still. For tethered means you just walk up and pick up the cable and attached. I’ve had both. I wouldn’t mind either but the tethered was a lot handier. And type 2 is here to stay so even if you move on from the Tesla it will
Work with all EV’s into the future.

So for any prioritization to work, you need 2 x CT Clamps - one connected to the AC output of your Inverter (to measure the Solar PV being generated) and one on the cable coming in from the Grid (to measure Import or Export). So I certainly expect you have the Grid CT Clamp right now. If you have one on the Inverter - then perfect.

You are not likely to need a Harvi. They are only to wirelessly bring a Grid or Inverter reading to a Zappi or Eddi if it's impossible or impractical to run a cable. However, what I'm not sure about is whether you need a hub or not. I'm not sure if the Zappi talks directly to the Eddi or whether the Zappitalks to the Eddi via the Hub. You can certainly set the priority of the Zappi over the Eddi on the Zappi control panel

Thanks. I’ll ask the solar guy tomorrow as they are MyEnergi suppliers here and they installed the eddi for me as part of the PV array.

Since you will already have the CT Clamps in place, once you install the Zappi, it will appear on the MyEnergi app. You can then drag the Zappi icon to 10 o'clock position, with the Eddi below it. The Zappi will then receive charge once excess exceeds 1.4kw

I don’t have the MyEnergi App.
My Eddie is hardwired right next to the consumer unit of that makes any difference.

I know I don’t have the hub or Harvi as it wasn’t required at the time.
The zappi I’m looking at comes with the Harvi now if that helps?

Guys,

Considering a zappi now to take account of excess solar PV generation.

I currently have my charger installed so all the wiring etc is fine and I can add or remove chargers as I wish and have done over the rears.

I have a 3kw array with a MyEnergi Eddi hot water divertor.
If I install the zappi, what do I need in order for eco+ mode to work?
Will it take priority over the hot water divertor or how does that set up
Work?

Thanks.

Myenergi were sure that another CT input was needed into the Eddi to "show" the battery charge/discharge, and hence apply the Supply Grid "Avoid Drain" setting on the Eddi...But may have to get guidance from them as to which cable this needs to be on.

Somehow they obviously thought that your battery was it's own totally separate unit, with it's own separate inverter unit. Whereas your Givenergy "box" of batteries is just that - connected to the Hybrid inveryer

So MyEnergi CT's would only be connected the the AC lead coming in or out of any unit to be measured.

You should be able to set an export margin in the zappi (and presumably in the Eddi too) under advanced settings, set it to like 50 or 100w. This should stop it pulling from the battery as it will keep a small bit of excess going to the grid when it diverts.

Thanks Mickeroo - Yep - I get the logic there. Have done just that, this evening

JBinWaterford

ChampionC - Yes, it's a hybrid inverter alright. Funny that now you've said that, it makes perfect sense that it's DC to/from the battery, tho I wasn't aware CT's can't "read" DC...every day a school day.

When you say:

"Therefore, you can only have two external CT's - one for Grid and one for the output of the Hybrid inverter. Obviously, the Inverter output will continue after sunset since it will be discharging DC power which has been converted to AC"

Again, makes sense, at least in so far as the Eddi has two external CT inputs (the first CT is "internal" to the Eddi I believe).
Myenergi were sure that another CT input was needed into the Eddi to "show" the battery charge/discharge, and hence apply the Supply Grid "Avoid Drain" setting on the Eddi...But may have to get guidance from them as to which cable this needs to be on.

In the meantime, I've "erased' the AC Battery CT Clamp setting as well as changed Eddi/Zappi comms channel (I have a home alarm on a possibly conflicting frequency), and lo and behold, the Zappi works okay again, and doesn't pull from either grid or battery whilst in Eco+ mode.

Feeling I've won a battle, tho not the war (yet !). Cheers :-)

If the battery is connected directly to the inverter, then it sounds like you have a Hybrid Inverter and that you are also trying to measure DC current going from a battery module back to the hybrid inverter. You cannot read DC current. You can only read AC.

Therefore, you can only have two external CT's - one for Grid and one for the output of the Hybrid inverter. Obviously, the Inverter output will continue after sunset since it will be discharging DC power which has been converted to AC.

So your CT on the DC cable between the battery bank and the inverter is likely screwing things up.

So how many CT's do you have ? You should have one on the Grid (configured as Grid), one on the AC side of your inverter (configured as Generation) and, if you have a SEPARATE battery / storage inverter (like a Powerwall), one on the AC side of this (configured as AC Battery). The Zappi and Eddi measure their own usage

Those CT's can be directly connected to either devices, and they will share this information between them, back to the Hub

CTs (set in Eddi);
1-Internal Load
2-Grid
3-AC battery

The Zappi also has a CT which the sparks installed but assuming the Eddi reads this one 'wirelessly' as not hardwired to the Eddi

The battery (Givenergy LiFePO4), is connected to the inverter and so believe it's an AC coupled battery. The added (3) CT clamp is around the live between battery and inverter.

When I'd only 1 & 2 (above) set in this configuration (and before Zappi installation), the Eddi behaved fine, and no battery drain for the immersion.

But now, with the immersion using battery current and Zappi using grid whilst in Eco+, I'm scratching the head a fair bit.

(Oh, and I've no hub / Harvi, if this is relevant)

Has anyone had an issue whereby their Zappi still pulls charge from the grid, even though set to Eco+ (despite changing Eco+ setting to 100% green) ?

Since quoted post, I've had Zappi installed and for a while Eco+ worked fine.

We then got an issue where the Eddi was heating the immersion with the battery (not previous an issue before Zappi installed).

Before installing the Zappi MyEnergi initially said Eddi and Zappi would communicate 'wirelessly' and an additional CT clamp wouldn't be required. However I calling again to explain Eddi was now taking battery current for immersion, I was told (by another lad) that an additional CT clamp was necessary

So, paid the piper, and installed it (onto live cable between battery and inverter, and into 2nd CT port in Eddi).

I think this is when the Zappi Eco+ mode started taking charge from the grid. (The smart boost/boost is inactive at this time).

I'd also set the Eddi CT to "AC battery" and Grid Supply setting to "Avoid drain"

I see you can extend the Zappi CT cables using Cat5.
Can you also shorten cables? I'm assuming this is possible, but want to check in case it's some sort of resistance wire where length is important.

I'm considering an installation where I would probably put a harvi in the box on the outside wall containing the electricity meter.
I don't need 5m of cable x 3 phases cluttering up the box.

Perfectly ok to chop them. This would be the way with most Harvi installs.

In fact, I had issues when I left the cables bundled up, so I absolutely needed to chop away about 4.7m

You might as well wait another few weeks.... this update only supports Zappi v2 right now.... Zappi v1 will get it "in the coming weeks".

For anyone who may be caught by the Zappi2 MyEnergi issue, MyEnergi have rolled out the long awaited v3 firmware (3.033) and they've also upgraded the hub (3.021) firmware too.

https://myenergi.info/zappi-2-firmware-release-v3-033-t2118.html

https://myenergi.info/hub-firmware-release-v3-021-t2142.html

For those with Solar PV and batteries there appear to be some updates in that area. Not sure if it resolves the issues that people have been reporting but worth a look anyway.
- "Improvement to way power allocation to batteries / power diverters is handled"
- Improved functionality with 3rd party diverters
- Zappi will now stop taking priority over 3rd party diverter if there is import for too long, e.g. when the diverter is boosting. Valid for CTs set to “Storage Only”.

Some other highlights....
- it will now support "Demand side response". I dont believe we have any electricity providers active in this area yet but its good to see it being added. Hopefully some electricity provider will provide that product here in the future.
- lock/unlock the Zappi from the app. Some people had fears of people stealing their electicity while they were out/holiday. New app coming on the 8 Aug to support it.

Spent practically the whole evening reading this thread to understand more about a pending Zappi install (self-install, via own sparks), and how to configure CT clamp/s etc, and was staring to think the hub was the way to go (We have PV/battery/Eddi).....Until I find out our home alarm works off exactly the same frequency that the hub does :rolleyes:
Also seems I'll have to get to grips with the Eddi / Zappi priority settings to direct PV KWs to house/battery/immersion/EV.
