Inverters are available with either a square/stepped/quasi or Pure Sinewave Output. The former is an approximation of an AC Sinewave. Suitable only for running simple loads like a mono-filament lamp, they will cause overheating, possible damage and poor performance of sophisticated loads like microwaves, power tools, audio visual equipment etc. Modified or Square Wave Inverters will also cause interference on computer screens, televisions and radios. |
