5.4 Activation
You can activate the Sunny Mini Central 5000/6000 when:
• The lid has been tightly screwed on.
• The AC (grid) cable has been correctly connected.
• All the DC (PV) strings have been connected and all unused DC plug connectors
on the underside of the inverter have been closed with the protecting caps.
Proceedings for Activation
Check whether string voltages comply with limiting values stated in chapter 4.2 „Re-
quirements: PV-Modules” (page 18). If the values are too high, the planner / installer
of the PV generator must modify the strings.
If the LED blinks again when the PV plant is reconnected to the inverter although
string voltages have been checked to be ok, disconnect the PV panel again and con-
tact SMA Technologie AG (see chapter 11 „Contact” (page 55)).
1.
Switch the circuit breaker on.
2.
Check whether the LEDs indicate trouble-free
operation of the Sunny Mini Central 5000/
6000 based on the following table. If this is the
case commissioning has been successfully com-
pleted.
If the lower yellow LED repeatedly blinks once a second for four
times, immediately disconnect the grid voltage and the PV gener-
ator from the Sunny Mini Central 5000/6000. The input voltage is
too high. The inverter might be damaged!
