Are you planning to buy a new inverter battery for your home? Overwhelmed with the many options around? Well, choosing the right inverter and battery are vital decisions as together they build the appropriate power backup solution for your home. The right inverter, inverter battery and battery capacity are fundamental in addressing the power woes.
The home inverter system consists of inverter and battery. It is the inverter that supplies power from the battery to the different home appliances when there is a power cut and charges it too. Thereby, it is imperative that you choose the right inverter depending upon your home needs.
Below are some of the essential things to consider when you have to buy an inverter for your home.
Calculate the Power Usage:
You need to first asses the power requirement of your home before buying an inverter. This essentially means calculating the power consumption of electrical appliances that will run on inverter in the event of a power cut. You can estimate by calculating the power ratings or wattage of different appliances and derive at total load watts.
Calculate Inverter Capacity:
To calculate the inverter capacity, you should know the volt-ampere (VA) rating of your inverter. If the VA rating is equal to the total load power, then the inverter will not be able to drive the load as there is also the power factor that needs to be considered. The power factor usually varies from 0.6 to 0.8. So, you can calculate the capacity in the below manner,
Inverter Capacity (VA) = (Total Power Needed) divided by power factor
Choose the Inverter Output:
There are different outputs of an inverter like a pure sine wave, quasi-sine wave and square wave. Most of the utilities provide pure sine wave, and you should choose an inverter with this waveform. If you opt for an inverter with any other waveform, it will have a negative effect on the appliances of your home and can even lead to damages.
Calculate Battery Capacity:
An inverter gets its power from the battery. It means that an inverter will run the home appliances in the event of a power cut depending on the battery capacity. The battery gets rated in Ampere Hours (Ah), and usually, a 12 Ah battery gets used in home inverters. You can know about the inverter battery capacity by doing the below calculation.
Total Power Needed in Watts x Backup Hours Required
Battery Voltage x Battery Efficiency x No. of Batteries
Choose the Type of Battery:
The inverter battery is designed to provide current for a more extended period. For this purpose, a tubular battery proves beneficial as against a lead acid and flat plate one. Along with opting for a tubular battery, you should focus on the battery manufacturer and check for other specifications like battery efficiency, capacity and charging and discharging capacity before you buy your inverter
