Commissioning the Inverter
Requirements:
☐ The AC circuit breaker must be correctly rated and mounted.
☐ The product must be correctly mounted.
☐ All cables must be correctly connected.
☐ The Wi-Fi antenna must be mounted.
☐ The battery must be commissioned and the latest firmware must be installed (see battery
manufacturer's documentation).
Procedure:
1. Switch on the AC circuit breaker.
2. Switch on the battery or the load-break switch of the battery (see documentation of the battery
manufacturer).
3. Turn the DC load-break switch of the inverter to
position I.
☑ After 1 to 2 minutes, all 3 LEDs light up. The start-up phase begins.
☑ All 3 LEDs go out again after approximately 90 seconds.
☑ The green LED starts to flash and, if the inverter is connected via Speedwire, the blue LED
also starts to flash.
4. 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.
5. 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 the feed-in
operation and the green LED will light up continuously.
6. If the red LED lights up, an event has occurred. Find out which event has occurred and, if
necessary, initiate countermeasures.
