Inverters
Modified Sine Wave Inverters Modified sine wave (or modified square wave) inverters are a good choice for a whole house inverter since their high surge capacity lets them start motors while their high efficiency lets them run small appliances economically. Most loads will run without trouble from a modified sine wave. It is suitable for a variety of applications such as induction motors (ie. refrigerators, drills ); resistive loads (ie. heaters, toasters); universal motors (ie. hand tools, vacuum cleaners) as well as microwaves and computers. However, some appliances will not operate or will run noticeably problematic if not on a pure sine wave. Problem loads: eg. many laser printers, copiers, some computers, light dimmers and some variable speed tools may not operate; some TV's and some audio equipment will pick up interference or background buzz; some digital clocks may not may not keep time; microwave ovens will have longer cooking times; and some small battery chargers may fail. Central heating ignition systems can be problematic. Pure Sine Wave Inverters A quality pure sine wave output is necessary for some applications such as running electronics or audio equipment. True sine wave inverters can run all types of load and are now available which are powerful, efficient and affordable! |
