Commissioning the Inverter
Qualified person
Requirements:
A means of disconnecting the inverter from the PV array must be present.
-
The AC circuit breaker must be correctly rated and mounted.
-
The product must be correctly mounted.
-
All cables must be correctly connected.
Procedure:
- Position the enclosure lid and first tighten the upper-left and lower-right screws, and then the remaining screws crosswise (TX25, torque: 6 Nm ± 0.3 Nm).
- Switch on the transformer.
- Switch on DC via the PV combiner box or the external DC switch.
- Switch on the AC miniature circuit breaker.
- All 3 LEDs light up. The start-up phase begins.
- All 3 LEDs go out again after approximately 90 seconds.
- Depending on the available power, the green LED pulses or is continuously illuminated. The inverter is feeding in.
- 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.
- If the red LED lights up, an event has occurred. Find out which event has occurred and, if necessary, initiate countermeasures.
