Problem Description
With some Sungrow inverters, particularly those in the -CX series, issues with active power control can occur depending on the installed firmware version.
Solutions
1. Update the Firmware
Ensure that the inverter firmware is up to date.
Outdated firmware is a common cause of control errors.
2. Adjust Settings in the Configuration App
In the configuration app, navigate to the menu item “Active Power Control” and follow these steps:
- Limit Active Power: Activate the toggle switch.
- Limit Ratio: Set the value to 0.0%.
3. Behavior After Firmware Update
After updating the firmware, perform this additional step:
Navigate in the configuration app to:
“Shutdown when active power limitation is at 0%”
Procedure:
- Enable the function and save.
- Then disable the function and save again.
This often fully resolves the issue.
