Huawei SmartLogger3000 User Manual

Parameter Description
IMD control dry contact Species the dry contact No. over which the SmartLogger controls
the IMD.
Set appropriate ports based on the cable connections between the
IMD and the SmartLogger.
PV module compensation
voltage direction
Species the oset direction of the PID module.
● PV– positive oset refers to raising the voltage between PV–
and the ground to above 0 V through voltage compensation.
Select PV– positive oset for P-type PV modules or the N-type
PV modules that comprise the solar cells whose positive and
negative polarities are on
dierent sides. For example, P-type
PV modules, HIT, CIS, thin-lm PV modules, and CdTe PV
modules meet the requirement for PV– positive oset.
● PV+ negative oset refers to lowering the voltage between PV
+ and ground to below 0 V through voltage compensation.
Select PV+ negative
oset 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
eect.
Working mode Species 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 rst power-on.
● After checking that the PID module functions properly, set Operation
Mode to Automatic.
Maximum system DC-to-
ground withstand voltage
Species the voltages between the PV side and PE and between
the AC side and ground in normal mode.
Species 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
Species 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.
