Hi, so the exact device type is STP5.0-3AV-40.
Okay I will get in touch with SMA. Thank you very much.
Hey Bimbo009, can you send me this pages too ?
Check this out, it should help you.
I already knew about the video on YouTube. Now, thanks to your help with the download link, I have discovered that my inverter does not support register 30577 (grid reference today / Netzbezug heute). Thank you very much. Then I have to build / program a counter somehow. Let’s see if I can do that 
Hi, I would have needed your help, I’m trying to get reasonable values for L1, L2 and L3 for amp, watt and volt. The template sensors that I found here do not work and the normal sensors only show the correct values when the system is active.
Hello everyone, I have a question, I recently tried out a Hacs integration (Solaredge Modbus) that also works with Modbus, you couldn’t modify such an integration for SMA.
In itself it should be mainly because of which addresses will be queried.
Hello,
I start by saying that I have a synny boy model SB TL6000-21
I have configured your code, nevertheless I get the following errors:

would you be so kind to suggest me a solution?
finally would you explain to me how to restart the server?
thank you.
Hello, to everyone who is interested, I got the SMA inverter integrated with the SunSpec integration in HA, see link instructions. Date November 2021.
my inverter is also about 10 years old, an STP 8000TL-10.
Same here mine is almost 10 years old, all the protocols are enabled, I can see it in my SMA portal, see it on the SMA website, have the user and installer passwords, yet I can not open it in my webbrowser nor can i get it connected to my HA, it always gives an error no matter what I do or try. Manually with Modbus or via the inbuilt new option of adding a SMA device, nothing works.
Inverter is Sunnyboy 3000 TL-21
Hello, the first thing is wrong, you don’t need a user or password for a Modbus query.
Try it as suggested in the January 3rd post above.
you can copy and paste it into your configuration.yaml so you only have to adapt the host to yours.
Thank you Stefan for thinking with me, I tried that too, plus I added Modbus support in configurations, but till now I can not get it working it does not read a single value.
Hi Thorsten,
thank you very much! It works for me with a Sunny Tripower 15000TL-30
I just have to fiddle out how to implement your template in my config but I think I will get through it.
You made my day
All the best from the Rhineland

Hi all,
I have a problem that I don’t understand.
Here you can see the sensor daily yield in the middle (PV_dagopbrengst) this is exactly right.
I added this sensor to the sun energy production as you can see in the second picture.
and in the third picture you see a total different outcome.
What am I doing wrong???
Thanks
@joris.mocka How did you get it to work? I have also the same inverter.
Try everything, but nothing works.

Did you enable Modbus as an Installer on the Inverter? You need to have the access and configure it with the Windows SMA Software.
I try to get a screen shot for you during the weekend.
Normally Modbus is disabled unfortunately.
Regards
Joris
I enable Modbus again.
How does your yaml file look?
Hello,
did anyone manage to read if the Inverter is currently in performance derating mode because of the 70% feed-in-limitation in Germany?
I tried it with Register Inverter.WModCfg.WMod --> 30835 which gives me
1079: Wirkleistungsbegrenzung P durch Anlagensteuerung (WCtlCom)
However all the corresponding WCtlCom-Registers are - according to the SMA documentation - Write only registers. And trying to read them gives me wrong values.
I would like to see it the inverter is currently in Derating mode to be able to turn on unnessecary stuff in my home
