Non Export setting

[Bolljohnny]

Hello,

I can´t find the non export setting when I have integrate the inverter? Is it possible to change the active power to non export via home assistant? I have a smart meter already installed

If you want to just limit your inverter to ZERO EXPORTS all the time, just run this service in HA Developer Tools: "Huawei Solar: Set Active Power Control to 'Zero power grid connection'"

Can also be set from the Fusion Solar web application, under the sDongle settings.

Most of this stuff is in the Wiki.... https://github.com/wlcrs/huawei_solar/wiki/Connecting-to-daisy-chained-inverters#combining-multiple-inverter-values

I don’t want it all the time, I just want zero export when it is negative spot price at nordpool. So I want to let the HA fixed it automaticly. Manuelly i can set the zero export via solar web but I want the HA todo this instead. Is it possible?

Yes use an automation in HA, that uses the Nord power price sensor as a condition (if more than / of less than) and with an action that calls the Huawei service to set max power to x kW and then in reverse step a higher or unlimited law to export when the price changes.

I want to set "the active power setting" to zero export via HA when it´s negative price but I don´t even find this setting in HA now?

I don’t want to set it to a specific kW value because I want my house to use everything it can. I have a smart meter that knows how much the house is consuming and how much that it is exporting lör 3 aug. 2024 kl. 19:22 skrev Roving Ronin ***@***.***>:

So as per above, use an automation to say:

1. When is less than $0.01, then call "Huawei Solar: Limit the power fed to the grid" and set to 0W.

2. Then conversely another condition that says when is more than $0.01 then call "Huawei Solar: Set Active Power Control to Maximum Feed Grid Power" (that will rest inverter to export the max it can produce).

Yes, but how do I do the call? Is it just to write "Huawei Solar: Limit the power fed to the grid" and set to 0W. ?
