Parameter
Description
Compensation offset voltage Specifies the compensation offset voltage between PV and PE
after the PID module operates stably.
The value ranges from 0–500 V, and the default value is 50 V.
● If the PV module compensation voltage direction is set to PV–
positive offset, the value indicates the positive voltage
between PV– and the ground, and the compensation range is
0–500 V.
● If PV module compensation voltage direction is set to PV+
negative offset, the value indicates the negative voltage
between PV+ and ground, and the compensation –500 V to 0
V.
NOTE
● If Compensation offset voltage is set to 500 V, the PID module
provides the maximum output to enhance the voltage compensation
effect. The output voltage amplitude of the PID module is automatically
capped to ensure the safety of a PV power plant. The output voltage
amplitude is also related to the maximum system DC-to-ground
withstand voltage and maximum output voltage.
● After this parameter is set and the PID module works properly, use a
multimeter that is set to the DC position to measure the voltage
between the PV input terminal of the SUN2000 and ground. (For PV–
positive offset, check whether the voltage between PV– and ground is
greater than or equal to 0 V. For PV+ negative offset, check whether
the voltage between PV+ and ground is equal to or less than 0 V.)
Clear data
Clears the active alarms and historical alarms stored on the PID
module.
You can select Clear data to clear active alarms and historical
alarms for the PID module.
6.3.15.2 PID-PVBOX Running Parameters
Parameter
Description
Operation mode
Specifies the current working mode of the PID module.
● Before setting this parameter to Manual, ensure that inverters
in a PV array are powered off and their DC switches are turned
off. This working mode is used during commissioning after
deployment or fault locating. In this case, the PID-PVBOX
delivers the output voltage based on the value of the
commissioned output voltage.
● Set this parameter to Automatic after ensuring that the PID
module works normally.
Output voltage (manual)
Specifies the output voltage when the PID module works in
commissioning mode.
Repair time
Set the recovery time for each day.
