What is the difference between Square Wave, Modified Square Wave & Pure Sine Wave Inverters?
Square Wave: Nova Electric neither recommends nor offers any inverters that produce a square wave. Square Wave units could be harmful to some electronic equipment, especially equipment with transformers or motors. The square wave output has a high harmonic content which can lead such equipment components to overheat! Square Wave units were the pioneers of inverter development and, like the horse and buggy, are no longer relevant for modern use. Modified Square Wave: The most common, general-use inverters available are of the “Modified Sine Wave” variety, usually available at more moderate pricing compared to pure sine wave models. Modified Square Wave (or “Modified Sine Wave” and “Quasi Sine Wave”) output inverters are designed to have somewhat better characteristics than Square Wave units, while still being relatively inexpensive. Although designed emulate a Pure Sine Wave output, Modified Square Wave inverters do not offer the same perfect electrical output. As such, a negative by-pr
