Thanks for the information swante !

How did you manage to configure it? I am on the firmware 03.02.08.R, Modbus server is active according to the External communication settings. Port is set to default 502. But the SunSpec Modbus TCP Home-Assistant integration fails to connect to it. Anything I may be missing? Maybe using the wrong Slave ID?

Edit: Never mind, found in the link you provided, that the device is found under the Slave ID 126

are u getting the production of the single strings through the Sunspec integration?

Has there been any further progress in this? I also have the Tripower X15. I just got the SunSpec integration working but is that still the only option?

Hi
I’m trying to get the sunspec connection to my sunny tripower x-15 running.

I have the integration installed, I type in the IP of the inverter, I set ID 126, port 502, but no connection can be established.

I have activated modbus server in the web interface of the inverter.

Do I have to do anything else in the interface of the inverter? Like add a modbus device somehow?
I have tried the stuff listed here: https://files.sma.de/assets/280725.pdf
But find it confusing, as I can not add a modbus device as described there. or I do it wrong.

Any help is appreciated.

bytheway. I have tried to access the tripower x15 via modbus from node red. Just a modbus reader node + debug node. I can read registers from it. In node red.

So I give my answer here to myself. The sunspec integration and the tripower only find each other, if there is actually sun. I tried to add the tripower in the evening, when there was no sun, and it didn’t work. This morning, no problem.

Sorry, small other question. I can get the entities from my STP both via modbus and via the SunSpec integration, but I’m looking for something else: is there a way to PUT directly into the API of the SMA STP? I would like to put the STP to sleep and wake it up again, either via an automation (with Nordpool prices) or on my mobile, with the Nabu Casa HA App, or both of course.
Any information on the API is welcome, as the SMA developers don’t want to give it to me.

There is no API in this sense. All SMA devices can be configured and controlled via Speedwire. But this interface is not documented.

What do you want to achieve by putting the inverter to sleep?

Is using Modbus 40915 maybe a solution?
40915 - Set active power limit (W)

This allows you to control the feed-in limit.

This is how I did that:
