6. 3 Startup
You can start up the Sunny Boy when
•
the enclosure's cover is securely screwed shut,
• the AC (mains) cable is connected correctly,
• the DC cables (PV strings) are fully connected and the unused DC plug connectors
on the bottom of the enclosure are closed using the protective caps.
How to Start up the Inverter
Check the string voltages again to make sure they are within the limits stated in section
5. 2 "PV Generator Requirements" (Page 15). If the string voltages are too high, the PV
generator's planner/installer should be called upon for assistance.
If despite checking the string voltages the LED signal occurs again when the PV gener-
ator is connected to the SUnny Boy, disconnect the PV generator from the Sunny Boy
again and contact
SMA Technologie AG (see section 13 "Contact" (Page 61)).
1. First of all, switch the line circuit breaker to the
"on" position.
2. Now look at the LED display and consult the ta-
ble on the following page to check whether the
Sunny Boy is in a fault-free and expedient oper-
ating mode. Once the inverter is in a fault-free
operating status, commissioning is successfully
completed.
Notice!
If the bottom yellow LED flashes four times at intervals of one second, the
grid voltage and the PV generator must be disconnected from the Sunny
Boy immediately! There is a risk of damage to the inverter resulting from
excessive DC input voltage.
