An inverter enables running devices that use alternating current, even when your power source is direct current. So it obtains direct current input, turns that into alternating current, and supplies the alternating current as an end product (output). Devices that you may run using inverters range from coolers to mini-fridges and onto computers, wi-fi routers among others. As long as devices require AC, yet what you have is DC, inverters are necessary. They serve as the bridge between the direct current power sources, and the alternating current required for the appliances. If you obtain power from solar panels and store it as direct current in batteries, inverters can help you. Similarly, if you have a UPS (which stores the main power in a battery in DC form), inverters are necessary. It is only through the inverters that DC current can be turned into AC current, which various appliances demand.

Top 10 Best Inverters in India-Buyers Guide
Features of Inverter
- The load that an inverter can bear is its most important feature. This can help you in working out which devices you can hook on (and which ones are out of the question). You can look at its VA rating, as well as its AC output watts rating.
- Safety protection features are also important in inverters. These include things like overcharging, overheating, and overload protection.
- The level of efficiency is also an important feature of inverters. There has to be some loss of power when turning DC into AC. But that should be minimal.
- Compactness can also be a vital feature in inverters. An ideal inverter occupies just a little space but does a lot of work.
- Compatibility with various batteries is also vital. So you check how many ampere-hours (AH) batteries it can work with.
- Another key feature is the inverter’s display. Modern ones are expected to have digital displays. Through these, you get to know how they (and the appliances connected to them) are working.
- Voltage selection can also be an essential feature in this sort of device.
Types of Inverters
At the most basic level, inverters come in three types.
- Firstly, we have those that we refer to as pure sine wave inverters.
- Secondly, we have those we refer to as modified sine wave inverters. And thirdly, we have the ones we refer to as square wave inverters.
- The difference between these types of inverters is in terms of how their output AC resembles that of mains electricity.
- So the pure sine wave inverters give output that is closest to what the mains electricity supply gives.
- The modified sine wave is close to what we get from mains electricity, but with some differences. And the square wave is somewhat further from what we get from mains electricity.
Buying Guide for Inverter
- The key thing to consider is the number and nature of appliances you wish to run with the inverter’s output. This can tell you what is the best inverter for home use. It should be capable of giving enough AC output to withstand the load. And the AC output it gives should be pure enough not to ruin the appliances.
- The next key thing to consider is the inverter’s warranty. Here, you ask three questions. First, how long is the warranty? Second, what does the warranty cover? And third, how easy or hard is it to actually make claims under the warranty?
- You then need to go further and consider how easy to use the inverter is. What is its weight like? How easy to install is it? How easy to maintain on an ongoing basis, is it?
- At yet another level, consider the inverter price. Don’t look at the figure alone: also consider the brand strength, useful features, and so on.
How To Use Inverter?
- Usually, the inverters have two sets of connectors.
- First are the ones that hook it onto the battery (whose DC power it is to turn into AC).
- Second, are those that hook it onto the appliances it is to supply AC output to. In most cases, the latter will be a socket.
- You then connect a power extension to that socket. Then you use the extension (which usually has several outlets) to tap power for various devices. Some inverters however have several AC outlets directly on them. With such, you don’t need to use an extension.
- It is important to appreciate that the inverter’s working depends greatly on the battery it is hooked onto. You thus need to be checking on the battery carefully.
- Sometimes, in case of overload, the inverters may trip. In such cases, there is usually a switch you can use to get it working again.
