How does a solar inverter work?

Please use a more recent browser. Solar inverters comprise a DC-DC conversion stage, to adapt voltage levels and implement the Maximum Power Point Tracking (MPPT) function, to maximize energy transfer from the panel and a DC-AC conversion stage to correctly shape current and voltage waveforms transferred to the AC grid.

What is a semiconductor inverter?

At the heart of modern inverters are semiconductor switches—most commonly SiC (Silicon Carbide) and GaN (Gallium Nitride) MOSFETs—known for superior efficiency and high-frequency performance. They support Pulse-Width Modulation (PWM) or Sinusoidal PWM (SPWM) control.
