Power Inverter VS Converter

If you have installed the solar panels at your home, then you always need to use some related solar products, just like power inverter and converter and so on, then how much do you know about them. Here, in this post, I would like to introduce them so that you can know the similarities and differences between them.

First, before our exploration, you had better know the definition between them. Power inverters and converters are both electrical devices to play a role of electrical power conversion when we use them. The power inverter is actually to convert direct current (DC) into alternating current (AC). The converter is a process of changing an electrical power source to another required one, such as voltage converter. Both are frequently applied to the circuit elements in the circuit, but there are still some similarities and differences between the power inverter and the converter.


Power inverter and converter are both considered as a kind of transformer, used for voltage conversion. The use purpose of the power inverter and the converter are the same, to realize the voltage converting from one kind of voltage and current to another kind of voltage and current suitable for the load. The power inverter performs the conversion from direct current power into high voltage alternating current. The converter also play the same function, converting the mains power into another desired power.

At the same time, both power inverter and converter uses PWM technology. Power inverter and converter both have adopted the pulse width modulation (PWM) technology, and the core part is an integrated PWM controller.


Although both the power inverter and converter are used for voltage conversion, actually they make different power sources conversions so they are suitable for different uses and applications.

The power inverter converts low voltage direct current (DC) into high voltage altenating current (AC). It can be used to convert the DC power like 12V, 24V or 48V from solar panels, or batteries into the AC household power like 110V, 220V, 240V, etc., to charging the appliances at home, in the car, outdoor or other remote sites where the AC power is needed.The power inverter fit for the situation where the AC electricity is not accessible but the DC power is available. Referring to the output wave form, the power inverters include square wave inverter, modified square wave inverter, and pure sine wave hybrid inverter, which can be chosen according to the practical applications.

At the same time, you still need to know that the converter is used to transform the supply power source to a required power source. The most common converters are to step down from 220V to 110V or step up 110V to 220V. Because of the different power environments of countries around the world, you can find the differences in the daily electricity. The converter offers great convenience for these guys when they choose to use them from all over the world.
