When it comes to power outages throughout the summer, Indian Tier 2 and Tier 3 cities are the hardest hit. Even though Tier 1 cities have fewer power outages, the outages are still intolerable in some locations. As a result, it is critical for houses to have a reliable power backup system that can help them get through the long and frequent power outages. If you’re having trouble with power outages in your neighborhood and need a solution, we propose bringing home an inverter battery combo. But, before you do that, there are a few things to keep in mind when looking for the best inverter on the market.

A UPS inverter and a battery are the two basic components of a home inverter system. Let’s have a look at both to see how to pick the best inverter battery combination.

Selecting the Best UPS Inverter

The UPS has two primary roles.

  1. When power is available, it charges the battery.
  2. During a power outage, it provides electricity to the appliances.

What you must realize is that not all inverters are created equal. In terms of the highest power they can deliver, they are different (VA Rating). They also use other technologies, such as sine waves or square waves.

What is the best way to choose an inverter based on its VA rating?

An inverter’s VA Rating is a measurement of the highest voltage and current it can deliver. It is expressed in VA (Volt Ampere). Because the VA Rating is dependent on the load consumption, you must first calculate your load demand before determining the VA Rating of the inverter you should purchase. Once you’ve determined the load requirement, use the formula below to calculate the VA Rating.

VA Rating = Loading Requirement / Inverter Power Factor

(Note: The Power Factor is usually between 0.65 and 0.8.) We’ll use 0.7 as an estimate.

Here’s how to figure out how much power you’ll need.

It’s simple to figure out how much power you’ll need. All you have to do is prepare a list of the items you’ll need in the event of a power outage. Let’s assume you need three fans, two tube lights, eight LEDs, and one LED television. Let’s imagine each consumes the following amount of energy.

1 Fan – 70 Watts

1 Tube light – 40 watts

1 LED light – 7 watts

1 LED television – 70 watts 

As a result, the total power need is (3*70)+(2*40)+(8*7)+(1*70)+(1*140) = 556 Watts.

Because VA Rating = Loading Requirement / Inverter Power Factor,

The VA rating is 556/0.7 = 795.

Quick Tip: If your load requirements are likely to increase in the near future, use inverters with a 10-20% larger VA rating. As a result, an inverter with the VA value of 900 VA is recommended in this scenario.

How do I pick an inverter that uses inverter technology?

As previously stated, there are two types of home UPS inverters: Sine Wave and Square Wave. The efficiency of current conversion from DC to AC differs between Sine Wave and Square Wave inverters. In comparison to Square Wave inverters, Sine Wave inverters offer a higher current conversion efficiency. Sine Wave inverters do not heat up or make a buzzing noise, unlike Square Wave inverters.

Square wave inverters, on the other hand, are less expensive than sine wave inverters. However, if you require an inverter to power voltage-sensitive equipment like laptops, microwaves, and refrigerators, a sine wave inverter is advised. Square wave inverters are better suited to operate devices such as motors.

How to Choose the Best Inverter Battery?

When shopping for an inverter battery, the two most significant factors to consider are battery capacity and battery type.

How do I choose an inverter battery based on the capacity of the battery?

The capacity of an inverter battery is a measurement of how much power it can store. It’s measured in Ampere Hours (Ah). The following formula should be used to calculate the battery capacity.

battery capacity: (wattage need * backup time * ageing factor) / (battery voltage * battery efficiency * inverter efficiency)

The following values are constant in this case.

  • Inverter aging factor = 1.25
  • Battery efficiency = 0.8
  • Inverter efficiency = 0.8

So, in the example above, where the power need is 556 Watts,

We also assume that a 12 V lead-acid battery is required to provide 2 hours of continuous power backup.

The capacity of the battery is ((556*2*1.25) / (12*0.8*0.8) = 181 Ah.

Quick Tip: Always choose a battery with a higher battery capacity because battery capacity degrades over time. In the above-mentioned situation, an inverter battery with a battery capacity of 200 Ah is recommended. 

What is the best way to choose an inverter battery depending on the battery type?

Flat Plate Batteries and Tubular Batteries are the two primary types of batteries. Both of these batteries are lead-acid batteries. The area you live in, the guarantee offered, the price, and other considerations will influence your battery selection. For example, if you reside in an area where power outages are brief but frequent, a flat plate battery is preferable because it charges faster. The reasoning is that because there is so little time (for charging a battery) between two power cuts, a flat plate battery would charge faster and be ready to use sooner. On the other hand, if you live in a region where power outages are frequent, a tubular battery is preferable to a flat plate battery because it has a bigger battery capacity.

Similarly, people looking for a battery that will last longer should choose tubular batteries with longer warranties. However, it is important to note that the price of a battery is directly proportional to the battery’s warranty. As a result, batteries with longer warranties are more expensive.
