One of the most critical and challenging components in an independent energy system is the inverter. You do not have to comprehend the inner workings to select a UPS inverter, but you should know some basic features, strengths, and limitations.
You should first specify your reasons to buy an inverter. It would help if you then learned about the available inverters. Manufacturers of inverters print on their specification sheets (commonly called spec sheets) everything you need to know. Here is a list of the factors that you should consider.
What Are the Types of UPS Inverters in India?
1. Pure sine wave
Like a standard wall socket, a UPS inverter supplies current from the battery cleanly and securely. The output from this inverter, identical to service supply, is in a sine curve which leads to noise less operations and increases life of connected appliances.
Since home appliances are built to run on this model, this is the best home UPS inverter. This system is effective without wasting much power if you wish to use high-powered appliances such as microwave ovens, televisions, and air coolers during a power outage.
If you need to operate multiple machines, a pure sine wave UPS inverter is the best option for the home, as it can change the voltage according to power requirements. However, they may be a bit costly.
2. Square wave
These inverters create waveforms that are square-shaped. As compared to the other two, square wave inverters are easy on pocket when compared with the similar rated sine wave inverter. However, if only need to run modest devices like Fan, LED lights or universal motors, then this is the right choice. However, such inverters can be noisy.
How to Choose an Inverter?
Step 1: Calculate Power Requirement
You need to define the power requirement to zero in on the best inverter for home. This involves recognizing devices such as lamps, tube lights, fans, TV’s, cell phone chargers, and Wi-Fi routers that would be connected during a power outage.
The electrical consumption of each unit you want to connect to the inverter will need to be defined, and the total consumption measured. This will determine the number of watt load that is required from inverter. This is the first step in your home’s choice of the best UPS inverter.
Step 2: Understand the Necessary Capacity
The total power consumption should, under optimal conditions, be the same as the capacity of the inverter. In the electrical system, however, incoming power is barely sufficient. For residential use, the power factor, calculated based on how effectively incoming power is used, is approximately 0.7 watts.
To arrive at the inverter power, estimated in VA, it splits the total electricity consumption in watts in step 1 by 0.7. If all the devices are used simultaneously, this is the full load of the inverter. If the exact battery capacity is not available, opt for one with greater capacity.
Reliable brands like Luminous will help you find the right one for you if you are looking for an easy way to choose a suitable UPS inverter.
Step 3: Decide on Battery Size
You now need to select the right battery size after choosing the best UPS inverter to allow it to operate optimally. The calculation of the battery size is in Ah.
Decide on a period during which the inverter is needed to provide backup. If you opt for a 600 VA inverter, for example, and want to use it for 4 hours, the appropriate battery size is as follows:
600 * 4 = 2,400VAh
Since the power of a standard inverter battery is 12V, the battery size is 2,400/12 = 200Ah
If the exact battery capacity is not available, opt for one with greater capacity, as with the inverter.
It is not a challenging task to select an inverter. Defining where it should be used, what kind of loads (appliances) you will power, and the maximum power that the inverter can handle will help select the best UPS inverter as per your requirement. There are leading manufacturers of inverters and batteries that offer a wide range of inverters to choose from. Check out their website or call on their toll-free number to get expert advice!
