Power inverter

The main function of an inverter is to convert direct current (DC) into alternating current (AC), and to change the voltage level into a stable 120 or 240 VAC that can be used by household appliances or “sold back” to the utility grid.

The word “inverter” was originally used because the output wave form produced by its circuits alternates between a positive and negative voltage. This device “inverts” the polarity of the power source (typically, a battery or photovoltaic array), causing the current to flow in alternating directions through the load. Hence the term “alternating current”.

Now, if you had a DC battery and someone taps you on the shoulder and asks you to produce AC instead, how would you do it? If all the current you produce flows out in one direction, what about adding a simple switch to your output lead? Switching your current on and off, very rapidly, would give pulses of direct current—which would do at least half the job. To make proper AC, you'd need a switch that allowed you to reverse the current completely and do it about 50‐60 times every second. Visualize yourself as a human battery swapping your contacts back and forth over 3000 times a minute. That's some neat fingerwork you'd need!

Our power inverter line has input voltages ranging from 12 volt dc power inverters, 24 volt dc power inverters and 48 volt dc power inverters. You will find a complete line of industrial grade power inverters, available in 12 volt, 24 volt and 48 volts. Our industrial power inverters are built tough and ready for use in commercial applications. We also offers 220 50hz export power inverters. The Export power inverters that we offer are modified sine 220 50hz power inverters, which are designed to be used in Africa and Europe. These 220 50hz power inverters are available in both 12 volt and 48 volt.

Inverters can be very big and hefty—especially if they have built-in battery packs so they can work in a standalone way. They also generate lots of heat, which is why they have large heat sinks (metal fins) and often cooling fans as well. Typical ones are about as big as a car battery or car battery charger; larger units look like a bit like a bank of car batteries in a vertical stack. The smallest inverters are more portable boxes the size of a car radio that you can plug into your cigarette lighter socket to produce AC for charging laptop computers or cellphones.
