Ordinary inverter: suitable for simple electrical equipment with low power quality requirements, such as lamps, electric fans, power tools, electric vehicle chargers, etc.
Pure sine wave inverter: suitable for equipment and scenes with high power quality requirements, such as medical equipment, precision instruments, computers, televisions, audio, etc., but also widely used in residential areas, commercial buildings, medical facilities, industrial automation and other fields.
Price and technical complexity
Price
Ordinary inverter: the technical requirements are relatively low, the manufacturing process is relatively simple, and the price is usually low.
Pure sine wave inverter: higher in the manufacturing process and technical requirements, need more cost input, the price is relatively high.

Technical complexity
Ordinary inverter: The design and manufacturing process is relatively simple, do not need to use too advanced technology and complex circuit structure, production and maintenance is more convenient and economical.
Pure sine wave inverter: In the design and manufacturing process, advanced technology and complex circuit structure are needed to achieve high-quality output waveform and stable performance characteristics, and the technical complexity is high.
