GW36K-MT is rather large inverter, if I'm not mistaken first time seen here.
Enable the DEBUG logs in the integration, restart HA and provide the log output so we can investigate.

Also, can you control the export limit via the SolarGo mobile app ?
If yes, does it use % of nominal power or W ?

[zelfkoelman]

I've debugging enabled. Need to figure out where to find te logs..

These are the options I have in the SEMS app:

Only used it to turn the inverter on and off.
What value sould I change?

Unfortunately the app is not working anymore since I've connected HA.

[mletenay]

Try SolarGo, not SEMS app.
SEMS works over cloud, SolarGo locally over Wifi and that's the one HA kinda mimics.

Hi mletenay,

The power limiting with the SolarGo app over Wifi app works. it uses %.

Before I can sent you log files... The GoodWe / HA integration seems to conflict with the SEMS cloud connection. It seems the settings in HA overwrite SEMS its function to shut down the system if needed. In the HA integration I can't find that option. So... as we are working with a live installation, I first need to be able to at least shut down the inverter remotely with HA.

Any thoughts?

[mletenay]

There is no shutdown setting in HA, so it can't interfere with SEMS.
There are reports that when you poll inverter from HA too frequently, SEMS stops getting data.

[zelfkoelman]

When I have HA connected to the inverter, "turning OFF" in SEMS seems to be overwritten (within seconds/minutes) by HA to "ON". Does this help?

If we can fix this, I'll be able to say in control, leave HA connected en send you the logs. The core issue is still that "power limiting" with HA seems to fail.
