The use of
sine wave power inverters has increased significantly in the last years. The basic principle employed in sine wave power inverters lies in the conversion of AC (alternate current) power to DC (direct current) power. This is helpful in emergency situations where there is a need to run electrical equipment. It is a simple, convenient and finds its use mostly on mobile applications such as boats and RVs.
Sine wave power inverters are often manufactured in the shape of small rectangles that consists of jack along with a trailing wire. It can be inserted directly on the dashboard or even plugged into cigarette lighter. Connections to the battery could be given directly with the help of the jumper-like cables.
The device contains outlets, probably one or two, for electrical cords that are standard. For RV parks, where there is lack of electricity, sine wave power inverters play a major role to power everyday household appliances.
Sine wave power inverters can be used even in a digital movie camera so that pictures could be taken without any interruption even though the battery goes down. When a power supply fails in a utility outage the sine wave power inverters becomes handy in such emergency situations. It can also be connected to a spare battery with charge. Even from the car the power inverter could be run into the house with the help of an extension cord. Important medical equipments, Radios, emergency lights are the best examples of sine wave power inverters.
There are different models of
sine wave power inverters available depending upon the wattage needed. The total wattage required is directly proportional to the total draw of the appliance that is being used. In order to plug in two devices in two-outlet inverter at the same time, the sum of their respective wattages along with a minimum value of 50% has to be taken into account for highest values in the power draw i.e., you may require at least 300 watt inverter for using DVD theaters and laptop which draws 100 watts each. In the engine of a vehicle the battery of the engine may discharge if the power inverter in that vehicle used continuously without running the vehicle. Hence to avoid this condition, for about 10 to 15 minutes the engine should be kept working by simply starting it. This process should continue once in an hour. Due care should be taken in starting a vehicle. Make sure that the garage is open else carbon monoxide in the exhaust may impart threat to human health. While traveling in the vehicle at road trips,
sine wave power inverters can be used. Here, the battery has to be checked about its condition. If the condition of the battery is good then no problem will arise for an additional draw.

TYPES OF POWER INVERTERS
Wave output in power inverters can be classified into three different types such as Square Wave, Pure Sine Wave or True Sine Wave and Modified Sine Wave. The output quality of the power varies with different wave signals. Therefore, they exhibit three different prices. The inverter that was made first was square wave inverters. The downside of these inverters was irregular power delivery. To overcome this shortcoming, modified sine wave inverters are used instead of square wave inverters. This modified square wave inverter delivers steady and capable power for most devices. More consistent output is obtained from pure since wave inverters but they are relatively expensive than other inverters. Medical devices and other rechargeable tools needs sine wave since these are sensitive equipment.
PRECAUTIONS
You have to be confident in choosing the inverters. Installation and maintenance of inverters should be done by trained professionals. The appropriate inverter should be fixed for particular devices. If there is any doubt about the issue, at once request the manufacturer to guide. This is highly recommended since the cost of inverters is high. Ensure safety while working with sine wave power inverters especially with car batteries. It may lead to serious injury when handled improperly. Therefore read the safety precautions carefully which is given along with the owner’s manual.
