You may be able to find a GoHz solid state frequency converter that will take 50Hz 220V input and output 60Hz 110V AC. Typically a solid state frequency converter works by rectifying the mains sine wave to charge a battery which is then inverted back to a sine wave to run equipment, so really the inverter could be designed to output whatever frequency is desired. That said, most 50Hz to 60Hz frequency converters will have an output frequency that is linked to the input so that they don't have to run off the battery all the time and via use of an autotransformer they can bump up the output voltage to fight brown outs. These configurations will not change the frequency of the output voltage.

When choosing a GoHz solid state frequency converter, understanding the equipment’s requirements and capabilities is key to finding the right fit. If the equipment is required to perform in an international environment, weigh the cost of the solid state frequency converter against the cost of replacing the equipment to be powered. Care must be taken to assure it is sized properly to meet the power demand of the connected load(s). Over-sizing the state frequency converter a bit is always a good practice. If selecting a low-cost solid state frequency converter, verify it has a pure sine wave output with less than 5% Total Harmonic Distortion (THD).

Another thing to keep in mind is the quality of the output waveform of a 60Hz to 50Hz frequency converter. If you have a sensitive piece of equipment that needs an input voltage that is truer to a sine wave than a square wave you will have issues with a cheaper frequency converter set up. The one problem with this is that depending of the quality of the 60 Hz to 50 Hz frequency converter, you will end up with a mostly square wave instead of a clean sine wave. If you are going to sensitive electronics like sound equipment it may not like that too well.

Simultaneously the 60 Hertz to 50 Hertz frequency converter is constantly feeding the input of a DC to AC pure sine wave inverter, to which you will connect your loads. The output of this sine wave inverter is configurable depending on the model of solid state frequency converter you purchase on GoHz.com, when the power goes out all that happens is the battery charger stops working.
