Diagnostics and data evaluation

8.1 Malfunction rectifi cation
The solar inverter is provided with an automatic diagnostics system which independently identifi es
certain faults and which can make them visible on the display.
Troubleshooting in the fi eld
In principle, it is always worth attempting a reset by reinitializing the solar inverter whenever 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).
(In the fi eld, the fi rst step is to scan for potential fault causes that could be picked up by the solar
inverter and result in tripping.)
Various key parameters can be scanned via the display, thereby enabling conclusions to be drawn
about potential fault causes.
