• 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 PV systems that require AC, but that are not going to supply large or complex loads like 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 or doesn't power any large or complex loads then a MSW inverter can be a good option.
