Power Output
The inverter can deliver 1500 watts for about 60 minutes .
The inverter must cool for 15 minutes before it can resume
Installation
operation at 1500 watts . Note: The wattage
rating applies to resistive loads .
Secondary Icons
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
Notice
Caution
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 .
