An inverter can be defined as an electronic device that is responsible for storing electricity from the grid in a battery and using direct current from a battery to convert it into alternating current for the load connected at output.
The best inverter for home depends on your requirements, which can differ from one household to another. Below are the criteria which one should keep in mind to select the best inverter for home:
Know the power requirements of your home. It is one of the essential factors for choosing an inverter that will be best for your home. You should calculate the daily usage of your electrical appliances and equipment which you want to run in case of a power failure. It can include your kitchen appliances, fan, CFL/LED, television, and tube light. Your total power requirement refers to the sum of power consumed by all equipment at home. In case of a power cut, all the appliances will not be running simultaneously, so find out the devices that you would want to run during a power outage; this value gives an average load—popular brand like Luminous offer a wide portfolio of inverters ranging from 300VA to 12500VA according to the load requirement of the buyers.
After calculating the peak load and the average running load in watts, convert it into VA. To know your VA output, you can easily divide the average running load with the power factor which is taken as 0.7. You should purchase your inverter with a higher VA rating to keep a large room for expansion in load.
From pure sine wave to quasi sine wave and square wave, the output of your inverter will vary significantly. To get the maximum level of efficiency, you should know which type of waveform is offered by the best inverter for home. For better performance of your home appliances, it is advisable that you should invest in a pure sine wave inverter. However, you can choose a square wave inverter for the best output if you want to operate electrical equipment at homes such as fans and lights—various brands offer a range of both Square wave & Sine wave inverters. Square Wave models available – Eco Watt, Shakti charge series, and Sine wave inverters – Eco-Volt, Zelio, iCruze, and Optimus range.
A battery is the storage unit of an inverter. The life and efficiency of your inverter will depend upon the quality of the battery you choose. To provide power backup, which is expressed in ampere-hours (Ah), the capacity of your battery is responsible. Based on suitability, battery capacity ranging between 80Ah to 220Ah is required for homes on an average. You need to make sure that your inverter supports which capacity range & the battery is capable enough to take the load of all home appliances that you want to operate during a power outage.
In the present scenario, most inverters use Lead Acid batteries to draw power in case of an outage & user can choose from the battery type like Tubular, flat plate & SMF (sealed maintenance free) according to the preference. There are few brands that have launched integrated inverters with Li-ion batteries. The benefit of a Li-ion battery is that it runs 3 times longer, charges 3 times faster, and 15% more efficient than lead-acid batteries. Luminous has launched Regalia range of inverters with Li-ion batteries.
With the advancement in technology, the use of inverters for the home has progressed. Inverters usually come with a shelf-life of more than 5 years. In many cases, an inverter lasts more than 7 to 8 years, and it can be considered as a one-time investment. Listed below are some features that you need to check before buying an inverter:
- LCD Display: Inverters with LCD display show the backup time remaining in case of a power cut and battery charging time when the grid supply is normal. It helps the user to plan activities efficiently and effortlessly. Luminous iCruze, Optimus, and Zelio series come with an LCD display.
- Fast Battery Charging: In areas that experience frequent power cuts, it becomes vital for an inverter to charge the battery faster so that the maximum backup is available in the next outage. Luminous Shakti charge, Rapid, and Optimus have fast charging facility.
It is important to consider these factors while buying the best inverter for home. When you are purchasing an inverter for home, reliable brands like Luminous offer a range of inverters with the latest technology.
