5.3 Activation
You can activate the Sunny Boy 3300TL when:
• The lid has been tightly screwed on.
• The AC (grid) cable has been correctly connected.
• The DC (PV) string has been connected.
Proceedings for Activation
Check whether string voltages comply with limiting values stated in chapter 4.2 „Re-
quirements: PV Modules” (page 15). If the values are too high, the planner / installer
of the PV generator must modify the string.
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 10 „Contact” (page 39)).
1. Switch the circuit breaker on.
2. Check whether the LEDs indicate trouble-free
operation of the Sunny Boy 3300TL based on
the table on the next page. If this is the case
commissioning has been successfully completed.
If the lower yellow LED repeatedly blinks once a second for four
times, immediately disconnect the grid voltage and the PV genera-
tor from the Sunny Boy 3300TL. The input voltage is too high. The
inverter might be damaged!
