Modern inverters, especially pure sine wave inverters, are designed to provide a stable and constant output voltage that is very similar to mains power. These inverters have built-in voltage regulation mechanisms to help keep the voltage within the acceptable range for most household appliances.
[pdf] 10200W pure sine wave hybrid inverter with up to 95% efficiency seamlessly converts 48V DC to 220V AC power and vice versa. Compatible with the grid, solar panels, and generators, it offers versatile power options.
[pdf] Using 2N3055 transistors for this 220V inverter can change low voltage DC like 12V into high voltage AC to around 220V. The transistors gives power to transformer and they work like power booster and help to make the final 220V output.
