OPERATING LIMITS
Power Output
Your PRO Series power inverter can operate on its full rated output for about 60 minutes. The inverter
must cool for 15 minutes before it can resume operation at maximum output .
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. If the motor surge
current exceeds the inverter surge capability then the inverter may shut down.
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 11.5V+/-0.3V , an
audible low battery warning will sound. Your inverter comes equipped with (2) low voltage alarm or
cutoff settings. The default setting is typically used for Professional Trucks. This setting will sound the
low voltage alarm at 11.5V +/-0.3V. The alternate setting is used for vehicles and RVs and will sound the
alarm at 10.5V +/-0.3V. To change the default setting to the alternate or vehicle setting go to page 20.
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.
