Points To Remember When Buying A Power Ac Inverter

By Expert Author: David Mullen

A power AC inverter is necessary when you are seeking ways of power conversions. Power supply from batteries or utility company comes in the form of direct current. The appliances you have at home need alternating current in order to function.

A power AC inverter is necessary when you are seeking ways of power conversions. Power supply from batteries or utility company comes in the form of direct current. The appliances you have at home need alternating current in order to function. They include TVs, home theaters, DVD players, refrigerators, microwaves you name it. The power AC inverter does this conversion for you.

Alternating current (AC) keeps changing its polarity. One moment the current flows this way and in the next it is reversed. This movement happens very fast like 60 times in every second. In order for this current to power your electronics, it has to be at a high voltage. A power AC inverter keeps converting the current for as long as the appliance is in use. Some of the inverters are inbuilt hence the reason why a TV works just fine the moment you plug it into the wall socket.

The pure sine wave inverter has come a long way. The inverters of yesteryears were noisy and cumbersome. If plotted mathematically, the wave generated by an alternating current is known as a sine wave. It is curved. What a pure sine wave inverter does is to square the curve. There is a good reason for having to square this wave. Some electronics are highly sensitive. These include video, audio, scientific and navigational equipment. On your TV, the square wave manifests as lines accompanied by a steady hum. The work of a pure sine wave inverter is to filter all waves emanating from the power supply to a form that is suitable for the device in question.

When shopping for an automatic voltage regulator, you have to match it to the amount of power supply. If you are using solar batteries, their output is 12 volts. The regulator must have a rating that exceeds this. An easy way of buying these devices is by looking at the ratings label. All in all, you should first determine the overall wattage of the appliances you intend to use. For example, a blender that runs on 600 watts and a coffee maker with the same requirement should lead you to buy a voltage regulator with an output of 1200 watts or more.

However, it is not always as simple as that. Appliances with motors as well as other electronic configurations require a high wattage to start up. In other words, every appliance has a peak rating. It is also indicated on the electronic device. The AC voltage stabilizer should have a rating higher than that on your television, blender or microwave. Nonetheless, there are special cases for microwaves. The wattage you see on your microwave is what it uses to heat or thaw food. The power output is twice the wattage displayed. This principle will also apply to a servo voltage stabilizer.

Before purchasing an off grid inverter, make sure you have confirmed its output as well. If you have devices that are sensitive to different types of wave output, you can seek directions from an electrical expert.
