Hi, thanks for the excellent video! I've bought a 3P Zappi and my installer is saying I need to spend another $500+ dollars on an isolator and cct breaker. Is that your experience ? Any suggestions on where I can source these at a better price? Thanks! Mark.

Great video! Could you explain how the Zappi monitors the import/export across the phases? I have a Nissan LEAF so was going with a single phase Zappi but my house has three phase power (with solar on two) so I’ll need to monitor all three phases to get an accurate picture of my import/export.

Agree, great video. I have the same ZAPPI V2 3 phase installed in my home which has a 3 phase supply. The 3 CT clamps that are supplied with the ZAPPI are attached to each of the 3 positive phase wires into the switchboard. These measure the power coming into the home or going out if you have solar. I have a 5 KW solar system on a single phase that supplies the switchboard and home with excess going to the grid. I added a HARVI with a single CT clamp that is attached to the solar output and this shows the live solar generation on the ZAPPI monitor screen. The HAVI communicates with the Zappi via blue tooth (or similar comms) and is not hardwired.

@@onionhead1007 my 3 phase Zappi was installed yesterday and sounds the same as what you’ve described. A nice tip for others is that the Harvi will fit inside the Zappi casing which keeps things nice and tidy.

Thanks for the video. I think this will be the charger we get as we have 20kw of solar panels and 3 phase power. What is the maximum this charger can put out assuming the car can take it? 22kw?

That is correct

I see that Chris has 3 CT clamps with the Zappi V2. That's fine for systems that use AC coupling between PV and the load/battery, but my system is DC coupled. So I'd want a sort of "DC clamp" or "Hall clamp" that can measure the power into and out of the battery. I've not heard of one of those for the Zappi, but perhaps with V2 it's now possible? I don't have 3-phase, so I'd rather not have to pay for three-phase capability when I can't use it. I had resigned myself to having to build my own "DC clamp", or modifying an Open EVSE (for which the schematic is available), but it would be nice to have something that just works out of the box.

It is my understanding you can buy the Zappi V2 in a number of combinations of the following: Tethered, Untethered, single phase, 3 phase, black or white.

emmerik64 there is no DC battery direct tracking for the Zappi but you can have the Zappi let the battery charge fist or not, just by adjusting some settings for import margin and/or green percentage. Not sure what functionality you are looking for. But the Zappi control options are flexible.

emmerik64 I don’t think it is related to the inverter. There are two versions of the Zappi. The single phase comes with one CT, and the three phase comes with three CTs. He will in addition require additional CTs to measure energy production; the Hub will require additional CTs, and he will require an additional CT for the battery. If he was to install the Eddi, he would require more CTs. Basically, he will independently of the inverter be measuring energy produced, energy consumed, and energy stored; this will tell the Zappi and the Eddi when there is surplus energy to consume for the EV’s battery or for hot water, and they will either be placed on a queue or simultaneously consume energy. In this case, the solar PV is large enough to probably provide simultaneously some energy for house loads, battery storage, hot water, and EV charging. If you find it useful, go to myenergi.com. Read the manual for the Eddi and the Zappi. Unfortunately, the flyer for both products provide limited information.

Ok so am I correct in thinking that your vehicle doesn't need to be able to accept 3 phase to be able to use this charger? I'm looking at a 3 phase zappi to charge a mg zs ev. I realise that a 3 phase charger is overkill to charge this particular car but I am trying to future proof. We have a 20kw solar system with 3 phase to allow maximum solar feed back to the grid. Hence considering a 3 phase zappi.

@@NaughtyGoatFarm yes, 100% correct. I have tested a 1 phase vehicle & also can charge my car in single phase mode. It’s really flexible, which is great for minimizing the solar export limiting, if you have that.

Mate, I'm a newbie. What's the advantages of a 3 phase over a single phase in Australia. Live in Victoria

Normally you can only export 5kW per phase so if you have a large system you can potentially export 15kW giving you more Feed In Tariff (FIT). Some retrailers are onto this though and limit your export to say 10kW so you dont send them bankrupt.

I think you showed an interesting phenomena. Energy going to the grid before charging 15.5-kWh. Energy while charging 6.0-kWh to the grid and 10.8-kWh to the EV. The sum of these last two is 16.8-kWh. This is within a matter of seconds showing an increase in production of 1.3-kWh. Is this really the result of a higher production or grid curtailment.

On that day there was inconsistent sunshine due to cloud movements. Varying readings from minute to minute. Chris' system is 28.8kW so that variation isn't significant. Don't quote me but I think the power above 15kW goes into the battery rather than grid curtailment. I will get Chris to respond.

E K Chris here, thanks for the question, I have a total of 23.4kW of inverter capacity & the Zappi can’t see the house loads or battery. It’s not important but during the day my base load on the house is the pool pump plus hot water. That’s about 3KW. Also when the system cannot export any more due to grid limits, my system automatically charges the battery with the rest. So all you noticed was the battery slowing down its charge. Also it’s not physically possible to import & export power from the grid at the same time.
