What is a Modified Square Wave Inverter?
A. Modified Square Wave Inverters produce a shaped square or triangle wave at 60 Hz. This translates to a high percentage of medium to high order harmonics distorting the 60 Hz sine wave cycle. This degree of “noise” may cause problems with some electronic devices. Though, generally Modified Square Wave Inverters will work with most appliances. However, they cannot be interfaced with the power line.
