The inverter has two LED indicator lights visible through the upper left corner of the

front panel. These lights indicate the inverter’s status.

If the inverter’s operating environment is safe to export power into the AC grid, the •

GREEN LED is illuminated.

If the operating environment moves outside the safe operating limits governed by UL •

1741, IEEE 1547, and IEEE 519, the RED LED indicator is illuminated.

The inverter continuously monitors:

The AC grid connection, to ensure the AC voltage and frequency levels are within 1.

safe operating limits per UL1741.

The DC voltage and current from the PV array ensuring safe operating conditions per 2.

UL 1741.

The inverter’s internal operational parameters, to ensure safe operating conditions 3.

exist within the operating environment.

If all three conditions are met, the inverter displays the GREEN LED.

If any one of the operating conditions are not met, there is a fault condition. The inverter

will then ﬂash the RED LED.

A solid RED LED illuminates when the PV array voltage is not within required operating

limits. The following conditions may cause this to occur:

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.
