As the summers are getting hotter, with each passing year, one cannot imagine a minute without electricity during the summer season. Similarly, for those working from home, power cuts are the last thing that these people can afford to have. In times like these, home inverters are the only saviors. And therefore, it is important that we buy the best inverter that provides adequate backup and is value for money. But now the question is how does one find out which is the best inverter available on the market. Well, to help you with that, here are a few questions that you must ask when looking for the best inverter for your home. Let’s take a look. 

1. What Inverter Capacity should I choose?

Inverter capacity is one of the most important factors that you should consider when looking for an inverter for your home. But for that, you need to calculate your load requirement which is a sum total of all the appliances that you would run during a power cut. Once you have calculated the average running load in watts, you need to divide it with the power factor (the value of power factor is 0.7) to determine the VA Rating (or inverter capacity).

If you want to cut short the process and quickly find out the right inverter capacity for your home, you can use the power consumption tool from Luminous India. The tool lets you pick the appliances that you would require during a power cut and basis that it recommends a suitable inverter capacity.  

2. How many batteries can be connected to the Inverter? 

The maximum battery capacity that can be or should be connected to an Inverter depends on the amount of charging current an inverter can provide. That’s because whether a battery gets charged fully, or not, within a reasonable amount of time, depends solely on the charging current that the inverter can provide. If the inverter cannot provide enough charging current then there’s no point connecting extra batteries. In fact, if the batteries do not receive enough charge and are deep discharged, it can even lead to the batteries getting damaged. It is recommended that the battery capacity should not be more than 12 times the charging current.  

3. Should I opt for a Sine Wave Inverter or a Square Wave Inverter?

Based on the waveform of the output AC power inverters deliver, they can be categorized into three main types. 

  • Square wave
  • Modified sine wave (also known as a quasi-sine wave) 
  • Sine wave (also known as a pure sine wave). 

Out of the three inverter types mentioned above, pure sine wave inverters are considered the best as they deliver a superior waveform that matches the waveform that we receive from the utility grid. Also, sine wave inverters make minimal noise and are ideal for running voltage-sensitive appliances. Sine wave inverters are, therefore, more expensive as compared to square wave and quasi-sine wave inverters.  Square wave inverters require minimum circuitry and are, therefore, cheaper. 

4. What warranty is being offered on the inverter?

While buying a high-quality inverter is important, it is even more important to ensure that the manufacturer offers a good enough warranty on it. The longer the warranty, the more it shows about the trust that the manufacturer has in their product(s). Before you buy the inverter, do a quick google search to read reviews of what the customers have to say about the company’s products. Also, we would suggest that you buy an inverter from Luminous India as they not only offer longer warranty periods but they also provide excellent after-sales support. 


These were some of the most important questions that you must ask at the time of purchasing an inverter. If you have any other questions then you must talk to an expert from a reputable brand such as Luminous India. All you need to do is visit their website and you would automatically receive a pop-up from their customer support team asking you if there’s anything that you need help with.
