Yes, the 48V inverter is more expensive than the 24V inverter. The most important thing is to choose the right inverter for your work. It is best to choose the inverter you need. Example: Your energy needs are around 1,000 to 5,000 watts, choose a 24-volt inverter system. [pdf]
[FAQS about Is it better to choose 24V or 48V for industrial frequency inverter ]
By definition, Low frequency power inverters got the name of “low frequency” because they use high speed power transistors to invert the DC voltage to AC power, but the LF inverter drives transistors at the same power frequency (60 Hz or 50Hz) as the AC sine wave power output voltage. [pdf]
[FAQS about Low frequency inverter and sine wave]
The low frequency inverters typically operate at ~60 Hz frequency. To produce a sine wave output, high-frequency inverters are used. These inverters use the pulse-width modification method: switching currents at high frequency, and for variable periods of time. [pdf]
