Zappi charge points

Thanks for the feedback. My meter is at the other side of the house with no way of routing cables through the house, the only option I can think of is having a cable run on the external of the house for 15 to 20m which visually wouldn't be great.

Yes, you can. Has to be done directly on the zappi and unfortunately not via the myenergi app.

deravarra, Iv'e a similar problem. My electrician installed the Zappi and we fitted one CT sensor. Recently I've had installed PV panels. I wasn't present when the the electrician of the company installing came. He told my wife that the set up would allow us to use the PV production to feed the car. But he didn't fit a second CT sensor. I presume he should have done this on the cable coming from the PV panels? We'll often have one EV parked and would use the car as the storage.

I got on to myenergi, to get their support - and afaic, they were absolutely useless. They would ask a question, and once i'd answer, no reply from them for about a week - only to ask if my issue was resolved.

Thankfully, I knew one of the folks involved in dealing with myenergi products and he knew the solution immediately. He will come to resolve - at my expense - but it will be sorted.

You sure ? ECO+ is totally reliant on seeing your defined portion of PV green energy. Don't think ECO has the same restriction - but then it won't stop charging. You'd need to do it manually, and may only pull a constant 1.4kW.

FAST mode could be used, especially if you set a low Device Limit.

He is right. If you don't have a battery system you only need one CT sensor. That one sensor goes on the main tails and from that sensor the Zappi can tell if you are importing or exporting... and that covers your point... "defined portion of PV green energy"

i.e. if its exporting then that is PV green energy that can be diverted to the car! ;)

You can add a second sensor for two reasons... to create priority between a battery taking the excess instead of the Zappi and also to simply see your total generation in the myEnergi graphs (i.e. just useful extra info).

But one sensor works fine but it needs to have the right settings in the Zappi and be installed with the correct orientation on the correct main cable. Sometimes installers put the sensor on backwards or dont configure it in the settings of the Zappi.

As above, you dont need a second sensor and your installer was correct in what he told your wife. What exactly is your issue with it? Have you changed the mode from "Fast" to "Eco+"?

Can you see the arrows on the screen showing power being exported when the panels are over producing?

Have you spoken to your electrician to discuss it as ultimately its his job to explain it to you and ensure the Zappi is configured right.... but one sensor is enough.

Trying to charge my car just off Solar using my Zappi. My understanding is that if it’s in Eco+ mode it will charge from solar once threshold of 1.4 kWh excess is reached. If the threshold isn’t reached, it just says waiting for surplus.

however, in my case, once threshold is reached, power is pulled from battery (charged overnight) and grid as well as solar. Have set the export Margin to 50W to see if makes a difference but it doesn’t. This was the situation this am. Any thoughts? Thank you.

Many thanks. Will having the ‘leaf’ function at 100% and export margin at 150W affect the 2-4am charging from grid? It’s usually first thing in the am that the car drains the battery. Thank you.

To be 100% sure too, charge the battery at the same time with Zero watts. It won't charge the battery but won't discharge it either

Ok. Have set export to 150w and still pulling from battery and grid. Don’t mind it pulling from battery as can top it up from Solar before dark - but from the grid is v annoying!

I thought the advantage of the Zappi is to be able to charge from excess solar when house has been powered.
