Grid Inverters For Your Business & Home

By:


Used primarily for solar energy applications, grid tie inverters can play a significant role in saving your hard earned money. You can use this inverter to power everything from electric shavers to music system or TV. They are commonly used in various solar energy systems that are connected with the grid. Like every other inverter its primary purpose is to convert DC power to AC.

A grid inverter is considered to be special because it can be used to feed power into the utility grid which can then be sold to the electricity supplying company. For instance, if your grid tie system supplies 500 kilowatt hours into the utility grid in a particular month, and you use 100 for your own needs, you can get compensated for the 400 remaining hours. However, depending on your geographical location the policies of this 'net metering' system may differ.

Now its important to understand how a grid inverter operates. The inverter transfers the solar power collected by the solar panels to the distribution panel in a building. The power may be used and if it is not used it gets transferred to the utility grid. At night or when there is no solar power available, the utility grid supplies the necessary power to the building continuously.

You will find many types of grid tie inverters in the market and the technology used by each of them may also differ. Normally, you will find most of them using either high or low frequency transformers. You will find some of them using no transformers at all. You can grab a high frequency model that follows a computerized process consisting of several steps to convert the power to high frequency AC, back to DC, and then to AC again and that too at the required output voltage.

Interestingly, you will often find that grid tie inverters that do not use transformers weigh less and are more efficient than the ones that use transformers. When you plan to buy a grid tie inverter make sure that you go to a reputed store. You may find them a bit expensive, but remember that it is a good investment for long term gain.
