Note: If there is a ground fault in the array, the „EarthCurrent-
Max“ 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 SB3800U and troubleshoot the array.
Note:
If there is adequate solar irradiation and the resulting PV
input voltage is sufficient, the SB3800U will automatically begin
feeding power to the utility grid.
Note: If the SB3800U is not operating as expected after the
commissioning procedure has been completed, refer to Section
7: Displays and Messages and to Section 8 for troubleshooting
assistance.
