26, How about the Output Frequency (Hz) of your Inverter?
Different frequency of different output voltage, about 50Hz or 60Hz.
North American 110-120 volt electricity is generated at 60 Hz. (Cycles) Alternating Current. Most foreign 220-240 volt electricity is generated at 50 Hz. (Cycles) Alternating Current. This difference in cycles may cause the motor in your 60 Hz. North American appliance to operate slightly slower when used on 50 Hz. This cycle difference will also cause analog clocks and timing circuits that use Alternating Current as a timing base to keep incorrect time. Most modern electronic equipment including battery chargers, computers, printers, stereos, tape and CD players, VCR/DVD players, etc. will not be affected by the difference in cycles.
