Sungrow SG50CX User Manual

• Before enabling the PID recovery function, make sure the voltage polarity of the
PV modules to ground meets requirement. If there are any questions, contact
the PV module manufacturer or read the corresponding user manual.
• PID recovery function and Q at night cannot be enabled at the same time.
• If the voltage scheme for the PID protection/recovery function does not meet
the requirement of corresponding PV modules, the PID will not work as ex-
pected or even damage the PV modules.
• If the PID recovery function is enabled, it only works at night.
• After the PID recovery function is enabled, the voltage of the PV string to
ground is 500Vdc by default, and the default value can be modified through the
App.
AFCI Function(Optional)
• AFCI activation
This function can be enabled to detect whether arc occurs in the DC circuit of the inverter.
• AFCI self-test
This function is intended to detect whether the AFCI function of the inverter is normal.
