Operation
STATUS LEDS
GREEN
¾Solid: The inverter is ON and providing power. If accompanied by solid yellow LED, unit is selling power to the utility grid. (See page 24 for a description of the Sell function.)
¾Flashing: The inverter has been turned ON but is idle. May be accompanied by the yellow LED. If not accompanied by the yellow LED, the unit is in inverting mode and is idle due to lack of demand. This can be because the unit is in Search mode. (See page 14 for a description of Search.)
¾Off: Unit is OFF. It is not waiting to provide power. Any power present is from another source such as the utility grid or generator. (See Startup on page 9, or the system display manual, to turn the unit ON.) The unit may also be a slave that is in Power Save mode. If so, the master inverter may still be providing power to the system. (See page 27 for a description of Power Save.)
YELLOW
¾Solid: The AC source is connected and providing power. Unit may or may not be charging the batteries, depending on settings. May be accompanied by green LED.
¾Flashing: The AC source is present but has not been accepted. If flashing continues, the unit is refusing the source. This can occur for the following reasons.
∼The AC source may have quality issues. External diagnosis may be required. (See page 15 for a description of input criteria. See the system display manual for diagnosis using the meter displays.)
∼In the system display, the AC Input menu is set to DROP. (See the system display manual for a description of the AC IN or AC INPUT hot key.)
∼In the system display, the High Battery Transfer (HBX) feature or the Grid Use feature intentionally disconnected the inverter. (See the system display manual for a description of these modes.)
¾Off: No AC source is detected. If a source is supposed to be present, confirm the voltage between AC HOT IN and AC NEUTRAL IN terminals.
RED
¾Solid: ERROR. Unit has shut down due to a critical problem which may be internal or external to the inverter. This LED is accompanied by an error message in the system display. See page 37 for a description of
error messages.
¾Flashing: WARNING. Unit has detected a
¾Off: No problems are detected.
