2 Product Description
• When the PID Zero function is enabled, there will be a power consumption of
less than 30 W in the PID Zero process.
• PID Zero can be applied to P-type PV panels, as well as N-type PV panels of
which the voltage between PV- and ground needs to be raised. Please disable
this function for N-type PV panels of which the voltage between PV- and
ground needs to be lowered. Contact the N-type PV panel supplier whether
the voltage between PV- and ground needs to be raised for PID recovery.
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.
The arc detection function meets the standard requirements, please test under
the working conditions as required by the standard.
Earth Fault Alarm
The device gives an alarm if there is a grounding fault. If the AC side is poorly grounded or
not grounded, the buzzer rings, and the LED indicator turns red.
