the meter will flash as shown, an alarm will sound to indicate Over Temperature Protect, and the unit will continue to operate. If the internal temperature rises to 40ºC (104ºF), the inverter will shut down to protect itself, the meter will flash as shown and the alarm will continue to sound.
NOTE Internal inverter temperature can rise due to being operated in a high heat environment or due to the fan or vents being blocked during operation (even in relatively cool outside air).
To restore normal operation, turn the unit Off and allow it to cool. The inverter will automatically return to normal operation after it has cooled.
The inverter can deliver 1500 watts for about 60 minutes. The inverter must cool for 15 minutes before it can resume operation at 1500 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
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
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
