Modified Sine Wave Inverter

Modified sine wave inverters are widely used in off-grid and backup power systems due to their affordability and efficiency. They are suitable for powering resistive loads like incandescent lights, heaters, and basic appliances. However, they can also run some inductive loads, such as refrigerators and motors, though with reduced efficiency and potential noise.
These inverters are common in RVs, boats, and solar power setups where cost is a priority over precision. They are not ideal for sensitive electronics (e.g., medical devices, laptops) due to harmonic distortion, which may cause overheating or malfunctions. Despite limitations, their rugged design makes them reliable for tools, pumps, and emergency lighting in remote areas.
