There are many reasons as to why people want to invest in a Sine wave inverter. Frequent disruptions in power supply, enhanced safety of appliances, are the main reasons. These inverters are the best alternative sources of power supply at times of long disruptions in the supply from the mains. A sine wave inverter is basically converts the 12 volt Direct Current to 110 volt Alternate Current that can be used to all the electronic devices. They can be connected to any battery pack which includes a car battery pack too.
There are a number of different types available in the market today and you will have firstly, be aware of the different criteria of selection. Here is a basic look at all the considerations that you will have to make.
- Wattage requirement
- Pure sine wave inverter or quasi inverter
- Heat rating
Here is a detailed explanation of each of the above three criteria:
The wattage requirement varies between a maximum if 1000w to a minimum of 300w to even 100w. The higher wattage value will indicate a higher stability in unstable conditions and more generation of power.
The next choice is between pure (also referred to as “true”) sine wave inverter versus those that employ quasi (also known as “modified”) waves. Pure sine wave inverters are those that ensure that there are no harmonic oscillations that can affect the working of electronic appliances. These devices will ensure that the electric waveform is a pure sine and there is no noise or interference being generated. But these units are costly and are not actually necessary to run every device. Household appliances run just fine on a unit that produces a basic modified wave.
The last important factor to be considered is the heat rating or the power rating. Most inverters will be able to sustain power for short periods of time before being reused as they need to be recharged and allowed to cool off. This duration can be estimated at around thirty minutes. And it will be vary depending upon the appliance you want to operate. It is best suggested that you go in for an inverter that has a higher heat rating than the appliance that will be operating using the sine wave inverters because otherwise not only will the inverter heat up very soon, it can also lead to problems in the functioning of the appliance and affect it negatively.
There are many companies that engineer, design and manufacture high quality pure sine wave inverters to meet all of the three above referenced criteria, the most widely acknowledged companies include Xantrex, Sunforce, Wagan, Go Power, etc.Tags: Direct current, harmonic oscillations, pure sine wave, pure sine wave inverters, true sine wave, true sine wave inverter
