Power and Protection Indicators
•
The Power and Protection Indicators include a green light,
a red light, an alarm and a current meter.
Green Light
Power On – The green light should remain On steady.
Red Light and/or Alarm
Current Overload – The red light will turn On momentarily,
then the inverter will shutdown. The inverter will
continue to check for appropriate current levels while
trying to restart the load.
Voltage Overload – The red light will turn On and the
inverter will shutdown. The inverter will continue to
check for appropriate voltage levels while trying to
restart the load.
Voltage Shortage – As a warning that the voltage is
getting low, the internal alarm will sound. When the
voltage is too low, the inverter will shutdown and the
red light will turn On. The inverter will continue to
check for appropriate voltage levels while trying to
restart the load.
Temperature Overload – The red light will turn On
momentarily, then the inverter will shutdown. The
inverter will continue to check for appropriate
temperature levels while trying to restart the load.
NOTE A momentary sound of the internal alarm
and/or flash of the red light is normal at start up.
Current Meter
The current meter indicates the
current drawn from the battery. It
will not indicate the current drawn
by other loads also connected to
the battery.
For long term operation, the current
meter should remain in the middle
of the bar graph.
Operating Limits

Power Output
The inverter can deliver 2500 watts for about 60 minutes.
The inverter must cool for 15 minutes before it can
resume operation at 2500 watts. Note: The wattage
rating applies to resistive loads.
The inverter will operate most AC loads within its power
rating. Some induction motors used in freezers, pumps,
and other motor-operated equipment require very high
surge currents to start. The inverter may not be able to
start some of these motors even though their rated
current draw is within the inverter’s limits. The inverter
will normally start single phase induction motors rated
at
1
⁄
2
HP or less.
Input Voltage
The inverter will operate from input voltage ranging
from 10 volts to 15 volts. Optimum performance will
occur when the voltage is between 12 volts and 14 volts.
If the voltage drops below 10.5V+/-0.3V, an audible low
battery warning will sound. The inverter will shut down if
the input voltage drops below 9.5V+/-0.3V. This protects
the battery from being over-discharged. It will restart when
the input voltage exceeds 12V+/-0.3V.
The inverter will also shut down if the input voltage
exceeds 15.75V+/-0.75V. This protects the inverter
against excessive input voltage. Although the inverter
has protection against over-voltage, it may still be
damaged if the input voltage were to exceed 16 volts.
