As of this week we’ll be switching to an dynamic energy contract. As such I would like to be able to limit the Solar power when their is a very high negative price. The GoodWe integration is up and running but I don’t understand to the full my own solution. 
I have the GW05K-DT G2 inverter and if I access that through the SolarGo app in supplier mode I can go to Advanced Setting - Power Limit and there enable Power Limit. Going back into HA and adjusting the Net Exportlimit updates the value if I look in the SolarGo app. However as soon as I hover in HA over the Net Exportlimit it starts to slide to the left and right and won’t send any updates any longer. That doesn’t work for me sadly enough.
However, I found out that there is another possible candidate to restrict the output, If I go into SolarGo - Advanced Settings - Safety Parameter Settings there I find the Active Power Mode. Going in that submenu I can enter a percentage between 0 and 100 procent being 0 no output and 100 full output.
I manage to control that element using Postman so I could integrate this into my HA automation. However, does anyone know of the difference between these two settings? In the end they both restrict the Solar output but I don’t fully understand if using the Active Power percentage is wise.
