• 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 reactive power generation 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.
• When the inverter is in the PID recovery state (the indicator blinks blue once at
long intervals and blinks at short intervals for three times), disable the PID re-
covery in the iSolarCloud App before manually powering on and maintaining
the inverter.
AFCI Function
• 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.
• Clear AFCI Alarm
When the inverter detects the AFCI alarm, it stops working. Clear the AFCI alarm so that
the inverter can restart the detection.
