I have the myenergi Zappi and is set to charging mode Fast, which before would have charged my EV as soon as it was plugged in, but the Next Connect app creates the schedules.

- An issue that I didn’t foresee, and has reared itself this evening. Scheduled charge from 21:30 which is great! Tesla began to charge, but my home storage batteries started discharging as well to the car; so I was ~4kwh from
the grid and ~ 3.5kwh from my FoxESS batteries.

Now I’ve been able to get around this issue when I was on the Next Drive Tariff between 00:00 and 07:00 by setting the batteries to force charge between the same hours, effectively 100% of the house load was being covered by the grid on the cheap overnight rate, including the EV charging and charging the batteries back to full. Then in the day time the solar/batteries take over and we become independent (as much as possible) from the grid.

However, with the nature of this tariff being that schedules could be at anytime of the day/week, I’m baffled as to how I can ensure that the load for the car is taken purely from the grid, and not draining my batteries to zero in the day time, which would result in then having to run the house on the more expensive electric unit rates.

Another forum mentions a Henley Block to hide the zappi charger from the inverter so it doesn’t see it as house load.

Seems to be getting complicated. Trying my best to do the right thing and move with the times, but issues beyond my general knowledge and understanding keep getting in the way.

Again, any information from anyone who maybe has had/having the same issue and maybe have worked a solution…would be greatly appreciated.

Might be possible by just moving the CT clamp so the battery can’t see the car load - would need a picture to tell. Otherwise, yes, reconfiguring the wiring by splitting in a different place with Henley blocks would do it.

@rwh202
I’ve sent a message to our electrician, explaining the situation. Hoping to get a solution, whether that’s via the CT clamp or a Henley Block.

@geoffers thanks for the link, I finally got my car to do the test charge. It’s set up to charge fully by tomorrow morning, will see if it works, everything seems fine at the moment. Eon need better instructions, I.e. the charger needs to be set to ‘plug and charge’.

If I charge during the day, my house batteries behave as yours, it doesn’t matter though as mine will charge during the night on the cheap electric, so if the car charges during the day, I will use little from the grid, solar and battery mainly so it costs even less to charge

@Spratto I will get this information to the solutions teams, I would have said if you havent got this sorted it would be best to speak to the installation/solutions team of the pod.

I will get the feedback sent over also.

@Wills170 my battery inverter cannot see the car charger at all as the CT is after the charger connection (see below)

So I can see 7.2 kW on the smart meter coming in and the inverter sees 0 as it supplies the rest of the house from the battery.

If you're lucjy you just have to move the CT, if you're not it's a rewire.
