Proceed with commissioning the Sunny Mini Central only after:
• the housing cover is securely screwed shut,
• the DC cables (PV strings) are fully connected and the unused DC plug connectors
on the bottom of the housing are closed using the protective caps,
• the Electronic Solar Switch is securely attached,
• the AC (power) cable is fully connected and
• the line circuit breaker is laid out correctly.
Commissioning Procedure
Step Instruction
1 First of all, switch the line circuit breaker to
the "on" position.
2 Now look at the LED or the display to check
whether the Sunny Mini Central is in a fault-
free operating status. If this is the case,
commissioning was successfully completed.
If the Sunny Mini Central shows other
messages or blink codes than those
described below, see the operating manual
of the Sunny Mini Central for their precise
meaning and possible solutions.
On!
