An inverter is a new addition in the Indian household that is getting its due recognition over time. A growing fancy over making life as comfortable as it can get, an inverter, gets a quick shout-out in the process. Even though its use was limited to important office spaces, it has now slowly become a staple. In fact, it is successfully making its way toward rural India, too.  

The concept of an inverter is simple, it converts the stored Direct Current (DC) from batteries to Alternating Current (AC) or electricity. As in, it is a ready-made power source in case of a power outage.  

With the growing work from culture and online classes, the need for an inverter is slowly transcending from being a luxury to a necessity. Moreover, it is very difficult to convert and distribute power without a reliable inverter. All these factors have ensured the novelty of the product declined and made it a more familiar experience. Not only that, it has also resulted in multiple reputed brands offering premium solutions for your inverter needs. 

Factors To Consider When Choosing An Inverter

Compared to other products buying an inverter can be a bit challenging since lots of factors are at stake. Moreover, any faulty move can lead to a catastrophe like a fire or jeopardize your entire home. So apart from the constraints of your budget, some other important factors you should consider before buying the product are: 

• Energy Efficiency: The major factor that you should consider before investing is an energy-efficient inverter. Apart from the obvious reason of being able to save energy and do your part, it goes easy on your bills too.

• Capacity And Load Handling: Every inverter has a different capacity to generate electricity. So you have to be mindful about choosing the one that is equipped to handle the load of your appliances. 

• Battery Compatibility: If you need an inverter to sustain an entire night, you have to pick a battery that can help with that kind of backup and carry the load. Moreover, the battery voltage and the battery chemistry need to match with the inverter too. It might not be a point of concern initially but for later usage, you have to make sure you have access to the same. 

• Warranty And Customer support: The after-sales services need to be top-notch for a product like this. Firstly, owing to the precarious nature of electricity and the risks involved, it requires active customer support for any setup issues. Moreover, an inverter is a long-term investment, so a warranty is a nonnegotiable.

Why Inverters Are Essential For Modern Homes

An inverter is like a storehouse of energy. It gathers energy from renewable sources, stores it, and provides it to you when needed. These devices convert Direct Current (DC) electricity from solar panels or batteries into Alternating Current (AC) electricity so that your appliances can use it. The idea is to have a constant source of power with you. But how exactly is this beneficial in the present modern Indian home? 

• • Backup power: The present fast-paced life doesn’t allow the space or time to afford a disruption. So having a power backup will ensure there is no interruption when it comes to your classes or work. 
  • Sustainable use: This is quick and easy for you to harness solar energy and consume power without any dent to the sustainability. 

• Voltage Regulation: Certain inverters are capable of manipulating the voltage situation and ensuring that the electricity supplied to your appliances remains stable. 

• Smart Technology: With Wi-Fi monitoring, app-based control, and many such innovations, the inverter ensures smart management of energy through the smartphone itself.
• Efficiency: the use of an inverter reduces energy waste, which directly leads to a less heavy electricity bill. 

Tips For Maintaining Your Inverter

An inverter needs to be taken care of to ensure its long-term productivity. But like any other electric appliance, it goes beyond the concept of just cleaning or charging. 

• Check the battery for acid levels in each cell to ensure there is proper functioning of the inverter. In case you see a dip in the float level, you can always top it up with distilled water. Moreover, in case you see a change in the color of the acid, it is a clear indication that the battery life is about to expire.
• You can check your battery health once it’s fully charged, which takes about 15 hours to unplug. Be sure to use the battery regularly to drain it to get an idea. 
• Store the battery in a cool and open space so that there is no external pressure on it or to prevent it from any kind of hazards. 
• Keep checking for overheating to facilitate longevity. Even though inverters are designed with built-in resistance and temperature control, an external check is always a good idea. 
• Lastly, loose connections and wiring can lead to damage to the entire setup. So a quick check on any faulty wiring is another significant maintenance procedure.
