nein, bei mir ist am gen-port nichts angeschlossen

• Gesamte Last an LOAD.
• 8kW PV am DEYE angeschlossen.
• 22kW über SMA Wechselrichter auf der Grid Seite, die ich per “Grid Tie Meter 2” die Daten in den Deye einlese.
• Speicher mit 106kWh brutto.

Bei mir mit C073 und 1184 extreme Schwankungen und egal was ich einstelle, es ändert sich nichts!

Egal was ich einstelle, der Bezug um den 0 Punkt bleibt konstant "schlecht".
Wenn ich -500W, 0W oder +500W einstelle, es ändert sich nicht.

Hat das noch jemand beobachtet?

Hier sieht man die Änderung.
Gegen 12 Uhr habe ich die neue Software installiert:

So war es gestern, mit diesersen Einstellungen:

So heute mit 0W Einstellung.

Ich hatte ja an den Support mehrere Mails gesendet.

Hello

 

I conducted some tests based on information found online:

1. As soon as AC-coupled inverters are used in the system, the regulation becomes ineffective.
2. This occurs regardless of whether the inverters are connected to the GEN port and enabled in MI, or whether they are connected to the load or grid side and the "AC couple on Grid side" or "AC couple on Load side" function is activated.
3. When I set -500W, it never actually reaches -500W consistently, but fluctuates between +700W consumption and -500W feed-in.
4. When I set the zero export power to 0W, the regulation improves.

I have to use the AC-coupled inverters and would be happy if the regulation then works well.

I would then like to set -50W to bring the consumption closer to zero.

 

By the way, I have a grid disconnect in my system.

I control this via a Loxone Home automation system.

It disconnects the house from the grid when:

• the state of charge (SOC) is between 50% and 95%.
• there is less than 700W of solar power generation and the battery charge is above 50%.

Jetzt die Antwort:

Dear，

Yes, you're right.

I didn't notice that you connected the AC coupling.

If the AC coupling is connected, setting the zero export power to a negative value will cause fluctuations in the grid power.
It needs to be set to 0 or a positive value for stability.

Meine heutige Antwort:

Hello

 

Are you working on an update that will also allow negative values with a good Regulation?
I would even be willing to be a BETA tester, if you want to test something.
