The inverter’s internal operational parameters to ensure safe operating conditions exist 3.
within the operating environment.
The inverter has two LED indicator lights visible through the upper left corner of the lid.
These lights indicate the inverter’s status.
Green LED is illuminated when:
All three monitored operating conditions are met.•
Inverter’s operating environment is safe to export power to the AC grid.•
Red LED flashes when:
Any one of the monitored operating conditions are not met.•
When a fault condition exists.•
The operating environment moves outside the safe operating limits governed by UL •
1741, IEEE 1547, and IEEE 519.
Red LED is illuminated when:
The PV array voltage is not within required operating limits, such as:•
At sunset, when the inverter turns off for the night. •
When clouds reduce the amount of available sunlight or when portions of the PV •
array are covered with debris.
Any time the DC output from the PV array drops below the inverter’s minimum •
DC operating voltage, the inverter turns off.
When the array is once again exposed to enough sunlight, the green LED illuminates, the
inverter’s auto-start feature begins, and after five minutes the inverter begins to export
power.
If the red LED continues to illuminate when there is sufficient sunlight for operation, verify
that no wiring connections are loose. If the wiring is secure, see the Troubleshooting section
for additional information.
The vacuum fluorescent display (VFD) indicates the inverter’s status and real-time power
output into the AC grid. This display provides the following information:
Inverter model type.•
AC power produced in real time (watts).•
Lifetime energy produced (kWh).•
AC voltage in real time (VAC).•
PV voltage input in real time (VDC).•
During start-up, a count-down timer.•
Fault code message if a fault exists or recently occurred.•
