Value Description
DO1,  PID01: Set appropriate ports based on the cable
DO2, and connections between the IMD and the SmartLogger.

PV– Select PV– positive offset for PV modules of P and
positive N-PERT types.

NOTE
For the specific PV module type, consult its manufacturer.
PV+ Select PV+ negative offset for PV modules of the N type
negative except N-PERT.
offset
Normal In normal mode, the PID module operates automatically
after the PID module, SUN2000, and SmartLogger
communicate with each other properly.
Commissi In commissioning mode, set Commissioning output
oning voltage. The PID module delivers voltage based on the
commissioning output voltage.
NOTE
To check whether the PID module functions properly, it is
recommended that Working mode be set to Commissioning
upon first power-on.
500–1500 Specifies the lower thresholds of the maximum voltage
V ranges between the SUN2000 DC side (including the
SUN2000, PV module, cable, SPD, and switch) and the
ground and between the SUN2000 low-voltage
grid-connection side (including the SUN2000, AC power
cable, SPD, and switch) and the ground in a PV power
system.
The default value is 1000 V. For the 1500 V SUN2000,
the recommended value is 1500 V.
0.2–100 You can set an alarm threshold for the impedance between
kΩ
the AC grid and PE for the PID module. If the detected
impedance is below the threshold, the PID module will
generate an alarm.
