• Modified sine wave (MSW): An inverter that outputs AC in a waveform that is rougher than a pure sine wave, but that is indistinguishable for most appliances. MSW are a more economical option for small systems that require AC, but that are only going to supply simple loads (cell phones, radios, lights etc.) Should not be considered if a system is intended to be used with certain types of loads - motors, laser printers, battery chargers, washing machines, high-end music equipment - as it can cause them to work improperly or damage them. Motors will consume roughly 25% more energy with a MSW inverter compared to a PSW inverter and the life of the motor will be shortened as that extra energy will be converted into heat. If a system doesn't rely on AC continuously, but only periodically for smaller loads, then it is an option that should be considered.
