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.
"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.
“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.

* Charge levels listed are approximate. Actual conditions vary
depending on battery condition and load. ** Inverter shutdown protects battery against dam-
age due to excessive discharge.

Illuminated Condition
All three lights Excessive discharge
flash slowly* (Inverter shutdown)
All three lights Overcharge (Charger
flash quickly** shutdown)
*Approximately ½ second on, ½ second off. See Troubleshooting section. Inverter shutdown
protects battery against damage due to excessive discharge.** Approximately ¼ second on, ¼
second off. Charger shutdown protects battery against damage due to overcharge. May also
indicate a battery charger fault exists. See Troubleshooting section.

Resetting Your Inverter to Restore AC Power
Your Inverter may cease supplying AC power or DC charging power
in order to protect itself from overload or to protect your electrical sys-
tem. To restore normal functioning:
Overload Reset: Switch operating mode switch to “OFF” and
remove some of the connected electrical load (ie: turn off some of the
AC devices drawing power which may have caused the overload of
the unit). Wait one minute, then switch operating mode switch back to
either “AUTO/REMOTE” or “CHARGE ONLY.”
Output Circuit Breaker Reset: Alternatively, check output circuit
breaker(s) on the unit's front panel. If tripped, remove some of the
electrical load, then wait one minute to allow components to cool
before resetting the circuit breaker. See Troubleshooting for other pos-
sible reasons AC output may be absent.
