Event Message Description and Actions

• Grid Frequency too low:
  The grid frequency at the inverter is below the minimum allowed. The inverter automatically shuts off due to legal requirements.
  Action: Frequently occurring? Contact your installer.

• Grid Frequency too high:
  The grid frequency at the inverter exceeds the maximum allowed. The inverter automatically shuts off due to legal requirements.
  Action: Frequently occurring? Contact your installer.

• Grid voltage too low:
  The grid voltage at the inverter is below the minimum allowed. The inverter automatically shuts off due to legal requirements.
  Action: Frequently occurring? Contact your installer.

• Grid voltage too high:
  The grid voltage at the inverter exceeds the maximum allowed. The inverter automatically shuts off due to legal requirements.
  Action: Frequently occurring? Contact your installer.

• Grid voltage too high for reactivation:
  The inverter cannot start feeding again because the grid voltage exceeds the legally prescribed switch-on value.
  Action: Frequently occurring? Contact your installer.

• Grid voltage Ø too low:
  The average output voltage over the legally prescribed period exceeds the allowed tolerance range. The inverter automatically shuts off.
  Action: Frequently occurring? Contact your installer.

• Grid voltage Ø too high:
  The average output voltage over the legally prescribed period exceeds the allowed tolerance range. The inverter automatically shuts off.
  Action: Frequently occurring? Contact your installer.

• Grid current DC offset too high:
  The DC current portion fed into the grid by the inverter exceeds the maximum allowed. The inverter automatically shuts off due to legal requirements.
  Action: Contact your installer.

• Residual Current too high:
  The residual current flowing from the plus or minus inputs to earth via the photovoltaic modules exceeds the maximum allowed. The inverter automatically shuts off due to legal requirements.
  Action: Contact your installer.

• L and N swapped:
  The live and neutral conductors are incorrectly connected. For safety, the inverter must not feed into the grid.
  Action: Contact your installer.

• PE not connected:
  The protective earth is not connected. For safety, the inverter must not feed into the grid.
  Action: Contact your installer.

• Insulation error:
  The insulation resistance between the plus or minus inputs and earth is below the allowed value. For safety, the inverter must not feed into the grid.
  Action: Contact your installer.

• Fan faulty:
  The internal fan of the inverter is faulty. The inverter will feed less power into the grid in certain situations.
  Action: Contact your installer.

• Device overheated:
  Despite derating, the maximum permissible temperature has been exceeded. The inverter feeds no power into the grid until it is no longer exceeded.
  Actions:

  1. Ensure installation conditions are met.
  2. Contact your installer.

• PV voltage too high:
  The input voltage at the inverter is above the maximum allowed.
  Action: Switch off the DC circuit breaker at the inverter and contact your installer.

• PV current too high:
  The input current at the inverter exceeds the permissible value. The inverter limits the current to the permissible value.
  Action: Frequently occurring? Contact your installer.

• Grid islanding detected:
  There is no grid voltage present (inverter running independently). For safety, the inverter must not feed into the grid and shuts off while the error is present.
  Action: Frequently occurring? Contact your installer.

• Time / Date lost:
  The inverter has lost the time settings due to being disconnected from the grid for too long. Yields cannot be stored, and event messages will have the wrong date.
  Action: Correct the time under Settings/Time/Date.

• Internal Info / Warning / Error:
  If these messages occur frequently, contact your installer.

• Self-test failed:
  An error occurred during the self-test, and it was cancelled. Contact your installer if the self-test is cancelled due to an error several times at different times of the day and it is certain that the grid voltage and frequency were within the limits.

• Faulty country setting:
  An inconsistency exists between the selected country settings and those stored in memory. Contact your installer.

• BCONV over-temperature:
  The maximum permissible boost converter temperature has been exceeded. The inverter feeds no power into the grid until it is no longer exceeded.
  Actions:

  1. Ensure installation conditions are met.
  2. Frequently occurring? Contact your installer.

• Boost converter defective / not detected:
  The boost converter is defective, and the inverter is not feeding into the grid or is feeding at reduced power. Contact your installer.
