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.

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.
