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 one-half 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 11.3V +/- 0.3V, an audible low
battery warning will sound. The inverter will shut down
if the input voltage drops below 10.3V +/- 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 15.5V+/-0.5V. 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.

Make sure
the inverter is
connected to
12V battery.
Check regulation
of charging system.
Check load for
proper operation.
Turn inverter on.
Check wiring
to inverter.
Observe
correct polarity.
