Sun2000-33KTL-A power control with AI 4-20mA

Hello, Andreas_TB295.
A forum user has proposed a solution to the problem, You can refer:

I found the solution.

I'm using a small part of the DRM function to reduce the production to zero.

Just need to connect the 4-20mA grid operator signal to AI2 or AI3 or AI4 (AI1 only 0-10v, not 4-20mA!)

Under Settings => DRM, choose the connection port (AI2, AI3 or AI4) and configure the startup current range regarding the signal of your grid operator.

In my case it was 17mA.

If the signal is upper 17mA, production is 100%

If the signal is under 17mA, production is reduced to zero !.

The idea now is asking Huawei to have the possibility to reduce the power smoothly regarding the value of the grid operator.

For example:

17mA: production at 75%

14mA: production at 50%

10mA: production at 25%

under 7mA production 0%

Today with the DRM function and only 4-20mA signal, we can't reduce smoothly the production without using DI inputs.

Thanks！
