Grid Feed-In Limitation Not Working for SolarEdge Inverter

DIY

Although I believe everything is set up correctly, the grid feed-in limitation for my SolarEdge inverter is not functioning as expected.

  • VenusOS version: v3.60
  • SolarEdge 10k inverter
  • The inverter is recognized as compatible with dynamic power control, and this feature is activated.
  • In the ESS settings, grid feed-in limitation is enabled and set to a maximum of 0W.

In my understanding, this should prevent any feed-in to the grid. However, 100% of the excess PV energy is still being fed back to the grid.

Could someone help me figure out what might be causing this or guide me on how to resolve the issue?

Thank you for your assistance!

Same here.

Before I did the trick with Homey and SolarEdge modbus app (requires SolarEdge meter) and that works fine. So I went back to this solution.

Have you made any progress with ESS?

Hi,

Ok i have checked out the problem.

Here is the Pull Request: Solaredge limit scale fix by chriswg3 · Pull Request #11 · victronenergy/dbus-fronius · GitHub

After that everything works with SE17K.

Hi, can you elaborate on this? What’s is it you’ve done?

Hi, i have recompiled the dbus-fronius package and debugged into it. Found the bug and reported it to victron (pull request). You have to wait until victron fixes this, or recompile the package for your own.
