  • ERROR CODE 11: E11 Grid Frequency Exceeds Permissible Range


    Grid frequency exceeds the value range stated in accordance with Safety regulations

    If it happens occasionally, it belongs to the short-time abnormality of the power grid, the inverter will return to normal operation after detecting the normal power grid, and there is no need to deal with it.
    In case of frequent occurrence but automatic recovery, please confirm if the grid voltage is outside the permissible range due to local grid conditions, try to modify the values of the monitored operational limits after informing the electric utility company first.
    If it cannot be recovered for a long time, please confirm:

    1. whether the AC circuit breaker is disconnected
    2. whether the AC terminal is in good connection
    3. whether the power supply line is normal
    4. whether the safety regulation settings are normal

  • ERROR CODE 12: E12 DC Current Exceeds Permissible Range


    The current exceeds 1Amp in stastic and 4Amp in dynamic

    Disconnect the inverter from the utility grid and the PV array, and reconnect it after LED turns off. If this fault is still being displayed, please contact the service.

  • ERROR CODE 13: E13 EEPROM Error (e.g. transition disturbance)


    DSP failed to read from EEPROM

    Disconnect the inverter from the utility grid and the PV array, and reconnect it after LED turns off. If this fault is still being displayed, please contact the service.

  • ERROR CODE 14: E14 Internal Components Communication Fault


    Duo Core – Master CPU abnormal communication with slave CPU

    Disconnect the inverter from the utility grid and the PV array, and reconnect it after LED turns off. If this fault is still being displayed, please contact the service.

  • ERROR CODE 15: E15 Bus-voltage High


    Voltage in bus-capacitor is greater than permissible value.

    Check the open-circuit voltages of the strings and make sure it is below the maximum DC input voltage of the inverter.
    If the input voltage lies within the permissible range while the fault occurs, please contact the service.

  • ERROR CODE 16: E16 Bus-voltage Low


    Bus-voltage is lower than standard Bus-voltage

    Check the open-circuit voltages of the strings and make sure it is below the maximum DC input voltage of the inverter. If the input voltage lies within the permissible range while the fault occurs, please contact the service.

  • ERROR CODE 17: E17 *DRED ONLY* DRM S9 Error


    DRM switch S9 fault

    Check the connection of DRM device. If the DRM device is connected normally while this fault occurs, please contact the service.

  • ERROR CODE 18: E18 *DRED ONLY* DRM S0 Error


    DRM switch S0 fault

    Check the connection of DRM device. If the DRM device is connected normally while this fault occurs, please contact the service.

  • ERROR CODE 19: E19 *3-PHASE* N-PE Voltage High


    N-PE voltage higher than permissible value.

    Check the connection of AC wires. Make sure the voltage of phase-to-phase, phase-to-netrue is right. If not, recorrect it.
