11 Troubleshooting / Problem Solving
The Sunny Mini Central is a complex high-technology device. As a result, the
possibilities for fixing faults on site are limited to just a few items. Should the Sunny Mini
Central display other blink codes or display messages than those described in section
8 "Commissioning the Sunny Mini Central" (Page 51), please refer to the operating
manual of the Sunny Mini Central to find the exact explanation of the display message
or the blink code and details on troubleshooting.
Do not attempt any other repairs than those described here, but instead use the 24-hour
replacement service (the Sunny Mini Central is made ready for shipping within 24 hours
and then given to a shipping company) and the repair service of
SMA Technologie AG.
