How to choose the right UPS Inverter?

You may be planning to either upgrade or purchase a new inverter.

You may be planning to either upgrade or purchase a new inverter. In any of these cases, it is extremely significant to use the most appropriate inverter. The power requirement for your home can be unique from other homes. Hence, instead of blindly installing the same inverter within your home, you need to know the determining factors. You need to choose a UPS inverter after knowing the Ups Inverter Price in India. Let’s look at the following section highlighting the description of different factors that help you choose the appropriate UPS inverter:

Power requirement:

One of the greatest significant factors you should know before choosing a UPS inverter is the power requirement. It simply implies that you need to determine how much power your electric appliance needs to run during the power failure incidence. For example, you need to determine the power requirement for your equipment like TVs, fans, tube lights, etc. Keep in mind that the power requirement is different than the power consumed by different electrical equipments.

To understand better, for example, you intend to operate 2 fans, 2 tube lights, a CFL, and a TV during power failure. The power consumed by a fan is 70W, 60W by a tube light, 25W by a CFL, and 120W by a TV. Hence, the total power requirement in our case is:

Power requirement = 2*70 +2*60 + 25 + 120 = 405W

Once you know the power requirement, you need to choose a UPS inverter considering the ups price along with the power requirement compatibility.

Determine the VA rating of the inverter:

VA (Volt Ampere) rating denotes the current and voltage delivered by the inverter to the appliances. If a UPS inverter runs with 100% efficiency then in that case, the power delivered by the inverter and the power requirement for the electrical appliances is the same. However, most UPS inverters come with efficiency ranging from 60% to 80%. So, the range of the power factor is 0.6 to 0.8. The corresponding efficiency is also known as the power factor of an inverter. It is the ratio of power needed by the appliances to the power delivered by an inverter.

The VA rating of inverter = Power consumed by the equipment (W) / power factor.

If the power consumed is 405W then the VA rating is 405/0.7 = 578 VA. You can easily find 600 VA UPS inverters and they will be the appropriate choice for your home.

Battery requirement:

Before making a buying decision just by looking at the ups price, you need to know the battery requirement. This is because the Ups Inverter Price In India may depend on this parameter as well. The lifespan and performance of a UPS inverter significantly rely on the battery performance. Now the questions that may arise are how much backup would a UPS inverter provide or how many hours it could operate all your appliances. This is nothing but battery capacity that determines the backup (measured in hours, expressed in Ah (Ampere Hours)).

The formula of battery capacity is:

Battery capacity = Power requirement (watts) * Back up hours (hours) / Battery Voltage (volts)

You can find batteries with capacities like 100 Ah, 150 Ah, 180 Ah, etc.
