    Table 7-3 Grid parameters

    Parameter

    Description

    Value Range

    Grid code

    Set this parameter based on the grid code of the country or region where the SUN2000 is used and the SUN2000 application scenario.

    N/A

    Isolation

    Specifies the working mode of the SUN2000 according to the grounding status at the DC side and the connection status to the grid.

    Parameter

    Description

    Value Range

    Insulation resistance protection (MΩ)

    To ensure device safety, the SUN2000 detects the insulation resistance between the input side and the ground when it starts a self-check. If the detected value is less than the preset value, the SUN2000 does not export power to the power grid.

    [0.037, 1.5]

Setting Feature Parameters

Procedure

  1. Choose Function Menu > Settings > Feature Parameters, and set feature parameters.

    Figure 7-10 Feature parameters
    Table 7-5 Feature parameters

    Parameter

    Description

    Value Range

    MPPT multi-peak scanning

    When the SUN2000 is used in scenarios where PV strings are obviously shaded, enable this function. Then the SUN2000 will perform MPPT scanning at regular intervals to locate the maximum power.

    The scanning interval is set by MPPT multi-peak scanning interval.

    • Disable
    • Enable

    MPPT multi-peak scanning interval (min)

    Specifies the MPPT multi-peak scanning interval.

    This parameter is displayed only when MPPT multi-peak scanning is set to Enable.

    [5, 30]

    RCD enhancing

    RCD refers to the residual current of the SUN2000 to the ground. To ensure device security and personal safety, RCD should comply with the standard. If an AC switch with a residual current detection function is installed outside the SUN2000, this function should be enabled to reduce the residual current generated during SUN2000 running, thereby preventing the AC switch from misoperations.

    • Disable
    • Enable

    Reactive power output at night

    In some specific application scenarios, a power grid company requires that the SUN2000 can perform reactive power compensation at night to ensure that the power factor of the local power grid meets requirements.

    This parameter is configurable only when Isolation is set to Input ungrounded, with a transformer.

    • Disable
    • Enable

    PID protection at night

    • When PID protection at night is set to Enable, the solar inverter will shut down automatically if it detects abnormality of the voltage compensation of the anti-PID module during the reactive power compensation at night.
    • When PID protection at night is set to Disable, the solar inverter will operate in grid-tied mode if it detects abnormality of the voltage compensation of the anti-PID module during the reactive power compensation at night.
    • Disable
    • Enable

    Power quality optimization mode

    If Power quality optimization mode is set to Enable, the inverter output current harmonics will be optimized.

    • Disable
    • Enable

    PV module type

    This parameter is used to set different types of PV modules and the shutdown time of the concentration PV module. If the concentration PV modules are shaded, the power drops drastically to 0 and the solar inverter shuts down. The energy yield would be affected since it takes too long for the power to resume and solar inverter to restart. The parameter does not need to be set for crystalline silicon and filmy PV modules.

    • When PV module type is set to Crystalline silicon or Film, the solar inverter automatically detects the PV module power when the PV module is shaded. If the power is insufficient, the solar inverter shuts down automatically.
    • When concentration PV modules are used:
      • When PV module type is set to CPV 1, the solar inverter can quickly restart in 60 minutes if the input power of PV modules drops drastically due to shading.
      • When PV module type is set to CPV 2, the solar inverter can quickly restart in 10 minutes if the input power of PV modules drops drastically due to shading.
    • Crystalline silicon
    • Film
    • CPV 1
    • CPV 2

    PID compensation direction

    When the solar inverter generates reactive power at night, an external PID compensation device (such as the anti-PID module) is required to perform PID compensation for the system. In addition, this parameter must be correctly set for the solar inverter.

    The solar inverter can generate reactive power at night only when it detects that the value of this parameter is the same as the compensation direction of the external PID compensation device.

    • If no PID compensation device exists in the system, set this parameter to Output disabled.
    • When the system uses the PID compensation device to increase the voltage of PV– with respect to ground to a value greater than 0 V, set this parameter to PV- positive offset.
    • When the system uses the PID compensation device to decrease the voltage of PV+ with respect to ground to a value less than 0 V, set this parameter to PV+ positive offset.
    • Output disabled
    • PV- positive offset
    • PV+ negative offset

    String connection mode

    Specifies the connection mode of PV strings.

    • When PV strings connect to the solar inverter separately (fully separate connection), you do not need to set this parameter. The solar inverter can automatically detect the connection mode of the PV strings.
    • When PV strings connect to one another in parallel outside the solar inverter and then connect to it independently (fully parallel connection), set this parameter to All PV strings connected.
    • Automatic detection
    • All PV strings separated
    • All PV strings connected

    Soft start time (s)

    Specifies the duration for the power to gradually increase when the SUN2000 starts.

    [1, 1800]

    Hibernate at night

    The SUN2000 monitors PV strings at night. If Hibernate at night is set to Enable, the monitoring function of the SUN2000 will hibernate at night, reducing power consumption.

    MBUS communication

    For solar inverters that support RS485 communication and MBUS communication, you are advised to set this parameter to Disable to reduce power consumption.

    • Disable
    • Enable

    Upgrade delay

    Upgrade delay is mainly used in the upgrade scenarios where the PV power supply is disconnected at night due to no sunlight or unstable at dawn or dusk due to poor sunlight.

    After the solar inverter starts to upgrade, when Upgrade delay is set to Enable, the upgrade package is loaded first. After the PV power supply resumes and the activation conditions are met, the solar inverter automatically activates the upgrade.

    • Disable
    • Enable

    RS485-2 communication

    If this parameter is set to Enable, the RS485-2 port can be used. If the port is not used, you are advised to set this parameter to Disable to reduce power consumption.

    • Disable
    • Enable

    Tracking system controller

    Selects a controller vendor.

    N/A

    Duration for determining short-time grid disconnection (ms)

    The standards of certain countries and regions require that the inverter should not disconnect from the power grid if the power grid experiences a short-time failure. After the fault is rectified, the inverter output power needs to be quickly restored.

PV String Access Detection

Context

  • Applies to large-scale commercial ground PV plants with PV strings facing the same direction.
  • In AC or DC power limiting scenarios:
    • If the PV string access type has not been identified, String Access Detection will be displayed as Not connected. The PV string access type can be identified only when the solar inverters restore to the non-power limiting state and the current of all connected PV strings reaches the startup current.
    • If the PV string access type has been identified, when some PV strings connected to the 2-in-1 terminals are lost, no alarm will be generated. If some PV strings connected to the 2-in-1 terminals are restored, the access type cannot be identified. You can determine whether both 2-in-1 PV strings are restored only when the PV string current reaches Startup current for 2-in-1 detection.
  • After setting the parameters, choose Function Menu > Running Info. > Details to check whether the PV string access status is normal.
