Dynamic Shading optimization
The algorithm tracks the full PV curve, compares local peaks, and tracks the highest power point, to improve the overall power generation. The function can easily be activated in the Sungrow iSolarCloud App.

Integrated AFCI 2.0 technology
The system analyzes signal and energy characteristics for an arc detection accuracy of 99.9%. Arcs will be detected in a range of up to 100 meters on the +/- string and a maximum DC current of 26A.

Feed-in limitation
So for installations with only the SG125CX P2 inverters, the Logger1000 is not needed anymore to fulfill zero-output restrictions. The meter can be directly connected to the inverter. This saves time and costs during installation.
