Hello everyone,
I have had a Victron photovoltaic installation for around 3 years and I have just purchased an EV charging station.I normally have everything configured and as shown in the screenshots below the devices communicate well together. On the other hand, regardless of the mode used Manual or Automatic, the EV Charging Station always uses energy from the grid and never excess solar production.
Could you please help me ?
Sincerely.
Eric
Hmm? Your question doesnt match the example images?
- you complain the charger is pulling from Grid
- but screenshots show that - out of 8 kW solar - youre charging 5kW and even feeding 4kW back to the grid?
Numbers don't align anyway: 8kW Solar - 1300 Battery Charge - 1300 AC - 5.7kW Ev..... where is 4kW FeedIn comming from?
Do you have the EV charger on AC-OUT 2
I don't know where the EV charger is connected (it's not me who installed it)
Looks like charger is connected before inverter, so it’s on grid. You can check it if you turn off inverter, than charging should continue. If so, there is no mistake - you have 4.7kWt going to grid from PV, EVCS “eats” it + feed a bit from grid (maybe to ensure sustainable charging power to your car)
You'll have to check with the installer where the EVCS is connected.
Thank you, I'm going to review this with him.
Do you know if it is normal for the screen to jump (see video attached) ??
A mí también me pasa lo mismo. Se queda la pantalla bloqueada en "loading". Encontraste la solución?

if you need my help, please write me
It seems like you have connected the ev charger in a way, that it is not visible to the multiplus / gridmeter?
In your example screenshot, the AC is less than the EV station consumes alone. This indicates, that the value of the ev station is fetched directly and displayed, but the system has no idea, where the load is actually located. (And therefore cant react properly)
It seems like you have connected it behind the gridmeter, which is therefore displaying 4000 FeedIn? When connected between the meter and the multiplus, the grid meter should read something like +1200 with the current numbers.
Same should be the case, when it is REALLY connected to AC Out of the multis - the multis should then recocgnize it as AC-Load (unless the victron ev-station is mathematically removed from these figures, but I don't think so)
(And AC should be 1300 + 5700, branching off the 5.7 for the EV)
At least in my case, consumption of the ev charger is always included IN the respective AC Consumption.
If you draw (or describe) how everything is wired together, we may help you to get that sorted.
Also you should mention, if you are using a grid-meter, or using the Multiplus-Metering without additional meter on the AC-IN side.
In the later case - with an AC-IN connected evcharger - it should theoretically work out, if you set the EV-chargers position to AC-In. IIRC, the system then will conclude, that the "AC-IN-Load" is actually the measurement of the multiplus + the AC-in connected ev charger.
Hello, so my solar installer came back today.
My EVCS is in fact on AC in, and in fact it works better because in auto mode it uses the additional solar production.
But I still have a problem that he hasn't seen on the other EVCS, the latter will go up to the maximum power or 32A while I don't have as much excess energy. It therefore uses the solar supplement and goes up to 32A using the network to compensate...
We have not found a solution at the moment so that it adapts well to the solar production supplement.
In addition, my screen constantly jumps, perhaps a sign of a device fault?
"In addition, my screen constantly jumps, perhaps a sign of a device fault?"
can you share a video?
On both AC IN and AC Out EVCS can use excess power.
Make sure both devices are correct configured and all the power is measured correctly in your system.
I try to share you the video with this link : https://streamable.com/nax3cb
How do I know if it is properly configured? Because even the Victron installer has never had this situation on his other installations...

Regarding the screen, it is most probably the issue described here:
can you share a video of the main webpage for the case when the power goes up without having excess power?
Two video of the main page, before starting cause SOC to low and after when the SOC is ok...
You can see on the second, that the EVCS no adapt to the production and excess solar. It's goes up maximum power.

And the second video is from the dashboard on VRM. I was asking for a video from EVCS main webpage. I want to see what data is EVCS receiving and how it is processed .
Or just write me when I can have a look.

You can see the EVCS main webpage at 5:50 on the second video...
I mainly filmed the VRM page because the two are perfectly identical.
Additionally in the video we can see how the EVCS behaves because there were big drops in production (cloud) and we see that it does not adapt at all and that it continues to rise up to 32A whatever happens.
At 5.50 I see that the EVCS power is increasing because the is more production than total consumption, so nothing wrong with that. Or I didn't understand what the issue is
There is only additional 5kw injected into the network.
Otherwise, the EVCS continues to go up to 7kW, so it uses the additional 5kW + 2kW from the grid.
I thought that the EVCS continually adapted to additional production so as not to seek energy from the grid. I would like EVCS to only use excess production and not seek energy from the grid !
Can you give me the schematic of your system?
I think the EVCS is installed before the meter, not after.
So even if the EVCS is consuming, the power still flows through the meter
that's the only thing that explains the behavior.
The order should be grid-meter-evcs
