Precautions for using Modified Sine Wave Inverter


Modified Sine Wave Inverter should avoid "inductive load". In layman's terms, high-power electrical products, such as motors, compressors, relays, fluorescent lamps, etc., are made using the principle of electromagnetic induction. This type of product requires a much larger (approximately 5-7 times) starting current than the current required to maintain normal operation when starting. For example, a refrigerator that consumes about 150 watts of electricity during normal operation can have a starting power of more than 1,000 watts. In addition, because the inductive load generates a back-EMF voltage at the moment the power is turned on or off, the peak value of this voltage is much greater than the voltage that the vehicle inverter can withstand, which can easily cause the vehicle inverter The instantaneous overload affects the service life of the inverter.
