The two types inverters whilst performing basically the same task are used for specific purposes. If simple loads like lights and resistive loads are being used then the quasi sinewave inverters will be adequate. Resistive loads are basically space heaters and immersion heaters, lights are standard tungsten or fluorescent based units. The quasi sine wave inverters can also be used on tools that do not have electronic speed controls and do not have high instaneous start up currents. Where equipment has high start up currents or electronic speed control or are synchronous stepping motors then the sine wave inverters must be used.
Where the equipment comprises of compressor driven equipment such as air-con units then special attention must be paid to the rating of the inverter and the battery bank size being used. On compressor driven equipment the start up current can be up to 5 times the normal running current and can cause problems if either the battery bank is to samll or the inverter is under sized. If a microwave is being used attention must be given to the rating of the inverter as the ratings of microwave ovens is normally the cooking power and not the true power comsumption which can be a third higher.
If televisions are being used it is advisable that sinewave inverters are used, on some televisions especially the new flat screen LCD units a frame bar line may be seen constantly moving on the screen when quasi sinewave inverters are used. On high-fi units a constant distinct buzz may also be discernable in the background especially on quiet pieces, again the use of the a sinewave inverter should prevent the noise being generated.
