These inverters use the pulse-width modification method: switching currents at high frequency, and for variable periods of time.

The term low frequency doesn't refer to the AC output you use in your home. That stays at a standard 50Hz. Instead, it describes how the inverter's internal electronics operate.

For inverters designed for residential use, the output voltage is 120 V or 240 V at 60 Hz for North America. Peak Efficiency The peak efficiency is the highest efficiency that the inverter can achieve.

The transformation of a high-frequency inverter steps up or down the voltage as needed, adjusting it to the desired level for the application. For example, 12V DC can be converted from a solar panel to 110V AC for household appliances.
