PV Overvoltage
The yellow LED is on for 5 seconds, goes out for 3 seconds, then flashes 4 times. This sequence is
repeated 3 times. If the status does not change, the blink code repeats itself.
The inverter has detected a DC input voltage that is too high for safe operation.
1. Check the DC voltage at the DC Disconnect.
2. If the DC voltage is greater than 600 V: Contact the planner/installer of the PV array.
or
If the DC voltage is lower than 600 V: Connect the Sunny Boy to the PV array again as
described in Section 5.5 "DC Connection", page 39.
If the message occurs again, disconnect the Sunny Boy from the grid and contact SMA (see Section
14 "Contact", page 90).
Ground Fault
Damage to the inverter due to overvoltage
• Disconnect the inverter from the PV array immediately.
High voltages in the PV array
Death or serious injury due to electric shock possible.
• Do not touch the PV array frame.
• Do not touch PE.
• Wait until there is no voltage before working on the PV array.
• Do not connect strings with ground faults to the inverter.
• Only electrically skilled persons may perform work on the PV array.
