Switching inverters

[harryboer]

Hi,
I'm loving the integration into HA!
I'm sure you're all aware of the hidden menu for ECU-R (sunspec) and ECU-C models: http://xxx.xxxx.xxx.xxx/index.php/hidden In this menu there is a function called 'switch_state'. here you can turn inverters on and off. Until recently I thought this was only possible with ECU-C models via adjusting the power output of the inverters. But I tried it with an ECU-R and it works! Now question is that it would be great to add this feature into this HA integration. In the Netherlands we have on certain very sunny days negative energy prices (when on a dynamic energy tariff), you then want to turn off the inverters for those hours. Now it would be great if we could automate that in HA. I'm no programmer so no idea how difficult or even possible this is but love to hear your thoughts on this! I found this on a German forum from someone who worked on this but not integrated into HA, but this might be a starting point? https://www.photovoltaikforum.com/thread/173721-apsystems-wechselrichter-mit-modbus-auslesen-und-beschreiben-yc600-qs1-ds3-usw/?pageNo=3#post3564312

If you can figure out what the full URL would be to change the switch_state for an inverter, I could probably add it. Lowering the grid frequency is the correct way in which the grid operators operate. If the grid threatens to become overloaded, they reduce the grid frequency, causing the inverters to switch off below the tresshold of the under frequency. This is a regulation that applies to all inverters.

Great! Thanks for testing. I can release a beta and see how it turns out for ECU-C owners (might add a check on ECU type as well on the official release).

[harryboer]

I think it should work for both ECU-C and the ECU-R 2162 model and not for the ECU-R 2160 model

"and on the 1 phase DS3 (with null wire) the voltage remains 230 Volts but it does go to 2-3 watts, so almost 0 W."

I do also have these low outputs on two panels (YC1000), thought it might be the nearby lamppost that generates some power ;)

@harryboer Just released v1.4.0 🎉

@HAEdwin Great! Thanks for including it in the integration! 👏🏼

hi, did you think it was possible to do this for eatch inverters ?
i explain even if i use a routeur in south of france there is days i export a lot of energy, my idea was to shutt one or 2 inverters during best sun hours .

[harryboer]

I don’t know the energy market in France but why do you want to do this? Is there a limit on how much you can feed back to the grid?

Normaly WE can t export . But if you don t export more than 1kw . It ok.But in summer Time i could export 5kw a day...So i would liké to limit and shutt some invertersLe 23 mai 2024 09:24, harryboer ***@***.***> a écrit : I don’t know the energy market in France but why do you want to do this?
