The output current and voltage of an inverter depend on its design and application. Generally:Inverters convert DC input voltage (commonly 12V, 24V, or 48V) into AC output voltage (typically 120V or 240V at 60 Hz in North America, or 230V at 50 Hz in many other countries)2.The output current is determined by the power output required by the connected load, the input voltage, and the power factor3.Inverters output a pulsed voltage, which is smoothed to produce a sine wave current suitable for powering AC appliances4.For specific applications, the output specifications may vary, so it's essential to refer to the inverter's datasheet for precise values5.
