8.1 Display
After a normal grid connection of the Sunny Mini Central, it takes approximately one
minute until the following display messages are shown alternately. For this, the DC and
AC connections must be wired correctly and the circuit breaker must be switched on.
The display messages shown before that only have the purpose of indicating the
initialization of the Sunny Mini Central and the process of controlling whether the power
supply requirements are fulfilled.
Display Description
PV Overvoltage
If the message on the left appears,
the AC and DC cables must be
disconnected from the Sunny Mini
Central immediately! There is a risk
of damage to the Sunny Mini Central
resulting from excessive DC input
voltage!
1. Check the DC input voltage again to make sure
it is within the limits stated in section 6.3.1
"Requirements" (Page 27). If the input voltage is
too high, contact the planner / installer of the PV
generator for assistance.
2. If despite checking the DC input voltages the
display message occurs again when the PV
generator is connected to the Sunny Mini
Central, disconnect the PV generator from the
Sunny Mini Central again and contact SMA
(see section 15 "Contact" (Page 92)).
Working Mode
The energy generated today and the current
operating mode are displayed first.
The current feed-in output and the solar generator
voltage are displayed after 5 seconds or when you
tap the housing cover.
After a further 5 seconds, or when you tap again, the
total energy produced and the time the converter has
been connected to the grid are displayed. Then the
cycle begins again.
