9. Diagnostics and data evaluation

9.1 Malfunctionrectication

The solar inverter is provided with an automatic diagnostics system which indepen-

dently identies certain faults and which can make them visible on the display.

Troubleshooting in the eld

In principle, it is always worth attempting a reset by reinitializing the solar inverter when-

ever an error message appears on the display.

To reset the device, proceed as follows:

1. Isolate the solar inverter from the grid (open automatic circuit breaker).

2. Switch off the DC disconnector.

3. Wait: approx. 1 minute.

4. Switch DC disconnector back on.

5. Switch in grid (close automatic circuit breaker).
