Parameter
Description
PV module compensation
voltage direction
Specifies the offset direction of the PID module.
PV– positive offset refers to raising the voltage between PV– and the
ground to above 0 V through voltage compensation.
Select PV– positive offset for P-type PV modules or the N-type PV
modules that comprise the solar cells whose positive and negative
polarities are on different sides. For example, P-type PV modules, HIT,
CIS, thin-film PV modules, and CdTe PV modules meet the requirement
for PV– positive offset.
PV+ negative offset refers to lowering the voltage between PV+ and
ground to below 0 V through voltage compensation.
Select PV+ negative offset for the N-type PV modules that comprise the
solar cells whose positive and negative polarities are on the same side.
NOTE
When designing a PV plant, the design institute or user should ask the PV module
vendor about the direction of voltage compensation for resisting the PID effect.
Working mode
Specifies the working mode of the PID module.
Manual mode: The PID module provides output based on Output
voltage (manual).
Automatic mode: The PID module operates automatically after the PID
module, solar inverter, and SmartLogger communicate with each other
properly.
NOTE
To check whether the PID module functions properly, it is recommended that
Operation Mode be set to Manual upon first power-on.
After checking that the PID module functions properly, set Operation Mode to
Automatic.
Maximum system DC-to-ground
withstand voltage
Specifies the voltages between the PV side and PE and between the AC side
and ground in normal mode.
Specifies the lower thresholds of the maximum voltage ranges between the
inverter DC side (including the inverter, PV module, cable, SPD, and
switch) and ground in a PV power system.
The default value is 1000 V. For the 1500 V inverter, the recommended
value is 1500 V.
AC-to-ground resistance alarm
threshold
Specifies the alarm threshold for the impedance between the AC side of the
PID module and ground.
You can set an alarm threshold for the impedance between the AC grid and
ground for the PID module. If the detected impedance is below the
threshold, the PID module will generate an alarm.
