Commissioning
6-2 SMA America SB3000US-4000US-11-SE1607
Note: If there is a ground fault in the array, the
„EarthCurrentMax“ error message will be displayed and the
GFDI fuse may clear. If this error message is encountered,
switch off the DC and AC disconnects to the Sunny Boy and
troubleshoot the array.
Note: If the Sunny Boy is not operating as expected after the
commissioning procedure has been completed, refer to
Section 7: Displays and Messages and to Section 8:
Troubleshooting.
Note: If there is adequate solar irradiation and the resulting
PV input voltage is sufficient, the Sunny Boy will automatically
begin feeding power to the utility grid.
Note: The Sunny Boy operates from the power produced by
the PV array and is designed for minimal internal DC-power
consumption. The maximum power that the Sunny Boy will
consume in normal operation is 7 W.
Note: Anytime the AC power is disconnected from the
inverter, either manually or as a result of an AC disturbance,
the inverter will wait 5 minutes after the AC power has been
restored to reconnect. When servicing the inverter, always
disconnect the DC first, then the AC.
