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 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
Inverter may not be able to start some of these motor even though their
rated current requirement is within the 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 (21V for 24V
versions) 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 (21V for 24V versions), you may
need to use a larger battery.
