What to Look for While Buying an Inverter for Home

When it comes to electricity, we Indians have a pretty good understanding of how badly it can affect your daily life cycle. During the summertime especially, power cuts and outages can cause you to effectively melt due to the heat. With years of experience living in Delhi, I personally know how bad it can get.

On the other hand, while we are moving into working from home territory. It becomes that much more important to make sure we can be online even during extended power cuts. We really cannot do much against power cuts, but we can at least be prepared for them and make sure you do get any work stuck.

You can get yourself an UPS for starters, but they can hardly take care of the heat. Yes you can connect a fan to a rather powerful UPS and use your computer on the side, however the backup time would be heavily reduced. Bigger UPS also cost a bit and in that money, the best idea is to instead invest in a good inverter for home and get rid of the power cuts interruption between the work.

We all are aware about the potential of inverters but you might not have much idea about how exactly to purchase one. There are a few things that you would need to understand before you go ahead and make that purchase. Inverters can last you an incredibly long time if you make some conscious decisions during your purchase cycle.

Before buying an inverter, you would need to consider a few things.

  1. Your total power consumption – Understanding how much power you require your inverter to put out when called upon is literally the first step in your purchase cycle. There is a simple method to calculate this power consumption. Basically, first check how many appliances you want to be powered by the inverter during any power cut. Once you have listed all these appliances, calculate the total power consumption of said appliances. For starters, a fan is 80W, a CFL bulb is 20W, a tube light is 40W, while a television is 120W. Simply calculate the total amount of power required to run all your appliances. Say, you need 4 fans, a television, 6 CFLs, and 2 tube light, these appliances roughly equal around 640W. Essentially getting an inverter that can support a load of 640W is a must for you.
  2. Inverter capacity – Once you have your power requirements, you would need to compute how much capacity you need your inverter to be. Inverter capacity is measured in VA and can be calculated by dividing your total power requirement by 0.8. So, a 640W power requirement would need an inverter of at least 800VA.
  3. Backup – The most important part of an inverter’s job is to provide a good amount of backup. If you get an inverter that has a capacity only a little over the total power requirement, you might not find it able to deal with the requirements for a long time. You can always invest in a bigger inverter that provides you with more than enough capacity and also allows you extended periods of backup without fail.
  4. Battery size and capacity – The formula to estimate battery capacity is as follows – [total load * backup hours needed] / battery voltage. So, generally battery voltage is around 12V, so according to the formula, to run 640W worth of appliances, you need a battery with the capacity of at least 320 AH, given you want your backup battery to run for 6 hours with a load of 640W.
  5. Brand and warranty – Inverters are long lasting appliances and can stay with you for years on end with the proper maintenance. A good branded product is obviously much better than a cheaper alternative, and it will show in the long run, where a cheaply made inverter will simply die out, whereas a better inverter could potentially last you years on end.
  6. More features – Inverters can be either common types, or more fancy ones that provide you with multiple incredible features. There are new inverters in the market that provide great backup potential, plus provide great features on top of that. An inverter with a digital display is great to check out the availability of mains, battery status, charging time, charge remaining and so much more. Inverters can also come with the ability to fast charge, where they charge much faster and can use this charge to power your home in case of a power outage. Most inverters also come with voltage and surge protection as well. Also, some really modern inverters can also be connected to your smartphone for remote monitoring.

Inverters are really great appliances that prove to be a huge help. Especially nowadays where we are essentially working from home, and might find the need for an inverter, since we cannot really trust the electricity system here. Besides the features and abilities we listed above, you only need to know about the types of inverters in the market. There are three kinds, Square Wave, Modified Sine Wave, and Pure Sine Wave inverters. For home use, the best kind of inverter is the pure sine wave that can support heavier appliances like computers as well. If you are living alone and only need to power a few appliances, a Square Wave inverter might be the best.

Inverters are great. Especially if you live in an area that experiences a lot of power cuts.
