Hey there @mletenay, @starkillerog, mind taking a look at this issue as it has been labeled with an integration (goodwe) you are listed as a code owner for? Thanks!

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.

[freekbrouwer]

Was there a fix for this? Iam having the same issues. I can shutdown / turn off the inverter from the SEMS app. But in HA with setting the export limit to 0% does nothing

What inverter model ? Since this feature is being actively used by dozens of users without any issues ...

This would be for a GoodWe Model GW3600D-NS Serial number starting with a 9

Hi!

I've got the GW3600D-NS here too.

The Grid export limit control in HA only seems to work if I first enable Power Limit in the inverter via SolarGo: Settings > Advanced Settings > Power Limit

After enabling this, controlling the Grid export limit in HA seems to affect the reported PV Power in HA. Setting it to 0% results in 0 W PV Power (in my case the slider units are percentage instead of W). So I assume for this model (or my setup?) it affects the total produced power, not just what's exported to the grid. (Which is in line with what the setting is called in the inverter.)

Thank you for replying,

I do not have the menu to go to settings--> advanced settings.

What is see is the following.

Please let me know what i am missing. I have gone through all the menus, and do have the option under Maintenance to shut it down but that seems unneeded.

Kind regards!

I think logging in as Installer (instead of Owner) shows different menu options. You could give that a try.

I am logged in as an installer now, it only added the Firmware Update button( which has been done already remotely via de service desk of Goodwe)
