Operating a Microwave oven with Your Power Inverter
The power rating used with microwave ovens is the “cooking power” which means the power
being “delivered” to the food being cooked. The actual operating power rating is listed on the
back of the microwave. If the operating power cannot be found on the back of the microwave,
check the owner’s manual or contact the manufacturer.
How This Modified Sine Wave Power Inverter Works
There are two stages in which this power inverter changes the 12 volt DC (or battery) power to
110 V AC (household current).
STAGE 1:
This inverter uses a DC to DC converter to increase the DC input voltage from the battery to
145 volts DC.
STAGE 2:
The inverter then converts the high voltage DC into 110 V AC (household current), using
advanced MOSFET transistor in a full bridge configuration. This design provides this Enerwatt
inverter with the capability to start and run difficult reactive loads, while providing excellent
overload capability. The waveform that is generated by this conversion is a “modified sine
wave” as shown in the diagram below.
Best use of Battery Power
Make sure any appliances are energy efficient and turned off after use.
Use fluocompact lamps. Wherever possible, charge with a renewable energy system (solar or
wind generator systems). Do not allow lead acid batteries to remain discharged for longpe-
riods of time, they lose capacity (Ah).
Please recycle in proper disposal site
Electronic products are known to contain materials that are toxic if improperly disposed.
Contact local authorities for disposal and recycling information.
This inverter is certified to be “lead free.” Transformers in this inverter contain nickel
composites. Nickel is a known neuro-toxin if ingested.
