High frequency inverter: High frequency inverters use high-frequency switching technology to chop DC power at high frequency through high-frequency switching tubes (such as IGBT, MOSFET, etc.), and then convert high-frequency pulses into stable alternating current through high-frequency transformers and filter circuits.
Volume and weight: Since high frequency inverters use high-frequency switching technology and compact circuit design, their size and weight are usually much smaller than power frequency inverters. This gives high frequency inverters significant advantages in mobile power supplies, aerospace, electric vehicles, and other fields.
Efficiency and energy consumption: Because frequency drive inverters use high-frequency switching technology, their switching losses and iron losses are relatively small, so their efficiency is usually higher than that of power frequency inverters.
Due to the use of high-frequency switching technology, high-frequency inverters have the advantages of small size, lightweight, and high efficiency, but they also have the problem of relatively poor output waveform quality.
In contrast, power frequency inverters can maintain high efficiency and stability under heavy load or overload. Output waveform quality: The output waveform quality of power frequency inverters is usually better than that of high frequency inverters.
That unit (Phocos PSW-H 5kw/120v) weighs around 110 lbs. I'm also considering it for my off-grid build, but I believe high frequency inverters generally weigh less and can double power on a surge for a couple seconds.
