The power rating used with microwave ovens is the "cooking power" which refers to the power being "delivered" to the
food being cooked. The actual operating power requirement rating is higher than the cooking power rating (for example, a
microwave with "advertised" rating of 600 watts usually corresponds to almost 1100 watts of power consumption). The
actual power consumption is usually stated on the back of the microwave. If the operating power requirement cannot be
found on the back of the microwave, check the owner's manual or contact the manufacturer.
Operating a Photographic Strobe with a Power Inverter
A photographic strobe or flash generally requires a pure sine wave inverter capable of surging to at least 4 times the Watt
Sec rating of the strobe. For instance, a strobe rated at 300 watts requires an inverter capable of surging to 1200 watts or
more.
Operating a Laser Printer with a Power Inverter
A laser printer generally requires a pure sine wave inverter capable of surging at least 6.5 times the maximum wattage
rating of the printer. For instance, a laser printer rated at 500 watts requires an inverter with a surge rating of at least
3,250 watts.
An inkjet printer does not maintain the same requirements as a Laser printer. Inkjet printers can be operated normally
with a modified sine wave inverter rated to handle the printer’s wattage requirement.
21. IM PROPER USE OF POWER INVERTER
1. Reverse polarity: For the models which have reverse polarity protection, inverter's fuse will blow out to protect the
other part inside the inverter when the inverter is connected reversed. It is possible to damage the part of the positive and
negative terminals due to high current after a short circuit. It will not affect the normal use after changing the fuse. For the
model which is not equipped with reverse polarity protection, it is possible that the electrolytic capacitor and the MOSFET
will burn out. When this occurs, a crack sound can be heard and smoke will be seen coming out.
2. When the input voltage exceeds the allowable voltage range of the inverter, the electrolytic capacitor inside the
inverter will burn out. In this case, a crack sound can be heard and smoke will be seen coming out.
3. Heavy overload. The overload protection power of the inverter is 10% higher than the rated Watts, mainly used to
start some appliances which require high start current. It doesn't support a long-term use. If customer uses the inverter
for long period of overload, it may cause aging of electronic parts and rapid increase of machine temperature. In more
serious cases, the electrolytic capacitor inside the inverter will burn out. If so, a crack sound can be heard and smoke will
be seen coming out.
4. The power inverter is used outdoor during rainy days or when water gets into the inverter. Because the inverter is
not waterproof, water entering any electronic part will cause short circuit and corrosion of such electronic parts. Failure to
dry after water entry will cause the electronic components to burn. When this occurs, a crack sound will be heard and
smoke will be seen.
5. The inverter output socket or terminal can only be connected to the appliance with the matching voltage. If the
customer connects the 110-120V appliance to the 120V inverter outlet, it may cause the appliance to burn out.
6. The AC output can only be connected to the electrical appliances. If connected to grid or generator, it may burn
electronic components. When this happens, a crack sound will be heard and smoke will be seen.
Note: Should any of above cases occur here is the proper operation: first turn the inverter off; then disconnect the
battery cable; finally disconnect the appliances when smoke dissipates. Please feel free to contact Customer Service for
technical guide or repair service. (When the part in the inverter burns out, a crack sound will always be heard and
smoke seen. Please keep calm and follow the step above. Attention: please don't use water to irrigate the inverter or it
will cause more loss.)
