Indicator Lights

Your Inverter (as well as an optional Tripp Lite Remote Control Module) is equipped with a simple, intuitive, user-friendly set of indicator lights. These easily-remembered “traffic light” signals will allow you, shortly after first use, to tell at a glance a wide variety of operating details.

“LINE Green LED”: If the operating mode switch is set to “AUTO/REMOTE”, this light will ILLUMI- NATE CONTINUOUSLY when your vehicle is con- nected to shore (or generator) power.

If the operating mode switch is set to “CHARGE

ONLY”, this light will BLINK to alert you that the unit’s inverter is OFF and will NOT supply AC power in the absence of a utility/generator source.

“INV” (Inverting) Yellow LED: This light will ILLUMINATE CONTINUOUSLY whenever con- nected equipment is receiving battery-supplied, inverted AC power.

“LOAD” Red LED: This red light will ILLUMI- NATE CONTINUOUSLY whenever the inverter is functioning and the power demanded by connected equipment exceeds 100% of load capacity. The light will BLINK to alert you when the inverter shuts down due to a severe overload or overheating. If this happens, turn the operating mode switch “OFF”; remove the overload and let the unit cool. You may then turn the operating mode switch to either “AUTO/REMOTE” or “CHARGE ONLY” after it has adequately cooled.

"BATT VOLT" or "BATT VOLT/CHRG CURR" LEDs: Depending on your model, this set of three LEDs will display different operating information.

750 and 1250 models: Whether the switch is in the "AUTO/REMOTE" or "CHARGE ONLY" position, the LEDs indicate the approximate charge level and voltage of your connected battery bank and alert you to several fault conditions. See "BATT VOLT" LED Function Chart for details.

2012 models only: If the switch is in the "AUTO/REMOTE" position, the LEDs indicate the approximate charge level and voltage of your connected battery bank and alert you to several fault conditions. See "BATT VOLT" LED Function Chart for details.

If the switch is in the "CHARGE ONLY" position, the LEDs indicate the approximate charge rate of the Inverter. See "CHRG CURR" LED Function Chart for details. Note: the charge rates in the chart are expressed as percentages of the Inverter's rated charging amps. Refer to the specifications to determine the charging amps of your specific model.
