The converters or inverters are used to convert the current of 12 or 24 volts (dc) battery, 220 volt current (AC). To choose an investor will take into account the rated power and the peak power of the inverter. The rated power is the power that can provide the investor in normal use and operation. While the peak power is that the investor may proporcionar for a short period of time. Investors modified wave (photo number 1) are used for virtually all types of devices even in some high-tech or inductive loads may not function properly because the wave is generated electronically. On the other hand, pure sine wave inverters (photo number 2) generate the same wavelength as that received at home. The wave modifiesIt gives but can be used with all types of devices always respecting the power that is able to provide the model we've purchased.
