I depend on devices and appliances for my work, and find power outages to be a major annoyance. Besides being inconvenient, they also interfere with my daily plans. So, last month, I planned to purchase an inverter. To know the appropriate size, I researched the steps for calculating inverter size. I found that your home's total power needs, inverter efficiency, and required backup time must be considered while determining the right inverter size.
Steps for Calculating Ideal Sizing Inverter to Battery Bank
To guarantee a continuous power supply even in a power outage, I must know the appropriate inverter or its battery size. I came across the following steps.
Determine which appliances you wish to keep running during a power outage.
Find each appliance's wattage. You can get it in the user handbook or on the label of the appliance.
To find the overall wattage, add the wattages of all the appliances.
Now, consider the power factor of 0.7 and the inverter efficiency between 60% and 80%.
After that, you can calculate the VA rating by dividing the total wattage by the power factor.
Decide how many hours you would like the inverter to provide electricity during the backup. Use the formula below for that.
Choose an inverter whose VA rating is equal to or higher than your calculated VA rating.
I tried it, but finally, I took the help of electrician to know the exact inverter size.
