PID Module Running Parameters

The parameter list provided in this document includes all configurable parameters. Configurable parameters vary depending on the device model. The actual display prevails.

Parameter

Description

Offset mode

Specifies the offset mode of the PID module.

  • Select Disabled if the PID module is not required.
  • Select N/PE if the PID module is required to use voltage output from the inductor virtual midpoint.
  • Select PV/PE if the PID module is required to use voltage output from the negative PV terminal. This mode is applicable only to Huawei SUN8000.
  • In the SUN2000 scenario, Automatic indicates the N/PE offset mode.

Output enabled

Specifies whether PID module output is enabled.

PV type

Specifies the type of the PV module used in the PV plant. For details about the PV module type, consult the manufacturer.

PV/PE offset voltage

Specifies the DC output voltage when the offset mode is set to PV/PE.

  • If the PV module type is P, set this parameter to P-type. In this case, the output voltage of the PID module is positive.
  • If the PV module type is N, set this parameter to N-type. In this case, the output voltage of the PID module is negative.

Operation Mode

Specifies the working mode of the PID module.

  • Manual mode: If Offset mode is set to N/PE or PV/PE, and Output enabled is set to Enable, the PID module outputs data based on Output voltage (manual).
  • Automatic mode: After the PID module and solar inverter communicate with the SmartLogger properly, the PID module automatically runs.
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.

Output voltage (manual)

Specifies the output voltage.

NOTE:

After this parameter is set and the output from the PID module becomes stable, use a multimeter that is set to the DC position to measure the three-phase (A, B, and C) voltages of the power grid to the ground, and check whether the voltages are the same as the configured values.

Maximum DC voltage

Specifies the PV-PE voltage when the normal operation mode is used.

If the PV module type is P, the parameter value indicates the highest DC voltage between PV+ and PE. If the PV module type is N, the parameter value indicates the highest DC voltage between PV– and PE.

Maximum output voltage

Specifies the maximum output voltage of the PID module.

If the offset mode is PV/PE, the parameter value indicates the highest DC output voltage between PV and PE. If the offset mode is N/PE, the parameter value indicates the highest DC output voltage between N and PE.

IMD access

Specifies whether the PID module and insulation monitor device (IMD) can operate in cycle mode.

Only the IMDs of mainstream suppliers such as DOLD and BENDER are supported, and the IMDs must have enabled dry contacts.

NOTICE:

You can set Periodic PID runtime, Periodic IMD runtime, and IMD control dry contact only when IMD access is set to Enable.

Periodic PID runtime

Specifies the operating time segment of the PID module when the PID module and IMD operate in cycle mode.

The IMD is shut down when the PID module is operating.

Periodic IMD runtime

Specifies the operating time segment of the IMD when the PID module and IMD operate in cycle mode.

The PID module is standby when the IMD is operating.

IMD control dry contact

Specifies 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

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.

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.

PID-PVBOX Running Parameters

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.
