3-8. Power output:
The 1500W inverter will operate most AC loads within its power rating.
When deeming whether a microwave oven can be operated by the 1500W
inverter, remember that the power commonly advertised for microwave ovens
are the cooking power (the power delivered to the food) not the power actually
consumed by the microwave oven. The microwave oven will consume 40%
to 100% more than its advertised cooking power. Check the rating sticker on
the back of the oven to determine its actual power requirements.
The 1500W inverter will operate small microwave oven (0.2 to 0.3 cubic foot
capacity) that draws about 1700 watts. It will provide 3 minutes of cooking
time. Some induction motors used in refrigerators, freezers, pumps, and
other motor operated equipment require very high surge currents to start.
The Power Inverter may not be able to start some of these motor even
though their rated current requirement is within the power inverter.
If motor is refused to start, observe the battery voltage indicator while trying to
start the motor. If the battery voltage indicator drops below 11 volts while
inverter is attempting to start the motor, this may be why the motor won’t
start. Make sure that the battery connections are good and the battery is
fully charged. If the connections are good and the battery is fully charged,
but the voltage still drops below 11 volts, you may need to use a larger
battery.
