charging doesn't start in "PV only"

[reach0775]

Hi.
charging doesn't start here in "PV only" mode. Of course I only refer to cases where there's constantly more than enough excess power.
When I kick the system like: selecting "now", or "min+PV" it starts. Then I stop it and then I select "PV only", then it works as expected. It just doesn't start automatically when the sun comes up.

Sure I see the errors in the log, but they appear to be temporary. When I open the browser, the system receives real-time data.

Diese Überschussleistung muss erstmal mindestens laut deiner Konfig bereitstehen um den Ladevorgang zu starten.

[reach0775]

Nice! Das heißt, ich muss unter Loadpoints eine Phase konfigurieren?
Klingt plausibel, mach ich gleich, danke. Allerdings: wieso startet er dann das Laden, wenn ich die bechriebene Prozedur mache?

[MvsBluewin]

that's right, and I don't need phase switching, I'm fine with one phase and only one phase is connected to the wallbox. The problem is that evcc doesn't start charging with one phase unless I first force it to charge after which it sees that only one phase is active. It seems the issue is that evcc considers connected phases rather than the UI setting in which I indicate only one phase is connected. Alternatively I can probably disconnect two phases of the Shelly pro so evcc sees only one phase connected ?

[mfuchs1984]

The UI setting is about how your charger is connected. When 3 phases are connected, the only way to charge with only one is a car or a cable with just one phase. If this is the case, configure your vehicles with phases: 1

[MvsBluewin]

got it, thanks will try that

[VolkerK62]

So, the Shelly is connected with 3 Phases and thereafter only one phase is connected to the wallbox?
evcc is detecting the phase voltages of the shelly and is setting the connected phases automatically.
In that case, the only possibility is phases: 1 at the vehicle (as @mfuchs1984 wrote)

[MvsBluewin]

that's correct - I kept the shelly on all three phases in case I reconnect all phases back to the wallbox (in case I want to speed up charging). I can't use the internal meter of the Elli as it doesn't play well with evcc/modbus. I did change my vehicle setting to one phase and that seems to have worked, thanks for the suggestion
