Commissioning the Inverter


Qualified person

Requirements:

  • The AC circuit breaker must be correctly rated and mounted.

  • The product must be correctly mounted.

  • All cables must be correctly connected.

  • Unused enclosure openings must be sealed tightly with sealing plugs.

Procedure:

  1. To avoid invalid serial numbers from being sent to the data logger, commission the inverter without being connected to the local network first. To do this, ensure that the RJ45 connection to the network is not established.

  3. Position the cover of the enclosure of the AC-Connection Unit on the AC-Connection Unit and first tighten the upper-left and lower-right screws, and then the remaining screws crosswise (TX 25, tightening torque: 6 Nm).
  4. Position the enclosure lid of the DC-Connection Unit on the DC-Connection Unit and first tighten the upper-left and lower-right screws, and then the remaining screws crosswise (TX 25, torque: 6 Nm).
  5. Connect the DC connector to the inverter in its original position.
  6. The DC connectors snap into place.
  7. Ensure that all DC connectors are securely in place.

  9. Turn the DC load-break switch of the inverter to position I.
  10. Switch on the AC circuit breaker.
  11. If the green and red LEDs flash simultaneously during initial commissioning, operation is stopped because no country data set has been set yet. For the inverter to begin operation, the configuration must be completed and a country data set must be set.
  12. If the green LED is still flashing, the conditions for activating feed-in operation are not yet met. As soon as the conditions for feed-in operation are met, the inverter starts with feed-in operation and, depending on the available power, the green LED will light up continuously or it will pulse.
  13. If the red LED lights up, an event has occurred. Find out which event has occurred and, if necessary, initiate countermeasures.
  14. Ensure that the inverter feeds in correctly.
