How to Calculate UPS/Inverter Battery Backup Time?

In today's world, where power outages are becoming more frequent and unpredictable, having an Uninterruptible Power Supply (UPS) or Inverter at home or office is essential. But how do you calculate the battery backup time of your UPS or Inverter? This question has been a hot topic lately, with many people searching for answers online. In this blog, we will guide you through the steps to calculate your UPS/Inverter battery backup time, using popular methods and techniques. So, let's get started and learn how to ensure uninterrupted power supply during emergencies!

There are different methods to calculate the battery backup time of your UPS/Inverter. Here are two popular methods:

Method 1: Using Battery Capacity and Load

The first method to calculate UPS/Inverter battery backup time is by using the battery capacity and the load. The battery capacity is the amount of energy that the battery can store, while the load is the amount of energy that your appliances or devices consume.

Step 1:Determine the Battery Capacity in Ah

To determine the battery capacity in Ah, check the battery label or manual. For example, if the battery is labeled as 12V 100Ah, the battery capacity is 100Ah.

Step 2:Determine the Load Wattage in W

To determine the load wattage in W, add up the wattage of all the devices connected to the UPS/Inverter. For example, if you have a computer with a power consumption of 150W and a monitor with a power consumption of 50W, the load wattage is 200W.

Step 3: Calculate the Backup Time

To calculate the backup time, use the following formula:

Backup Time (in hours) =Battery Capacity (in Ah) * Battery Voltage (in V) * Battery Efficiency (in %) / Connected Load (in W/h)

For example,

1. If you have a 1500VA UPS with a 12V 100Ah battery, and the total wattage of your load is 800W, the backup time can be calculated as follows:

Backup time = (battery capacity ÷ power requirement of load) × 0.7

Backup time = (12V × 100Ah ÷ 800W) × 0.7

Backup time = 1.05 hours or 63 minutes

Note: The factor of 0.7 is used to account for battery efficiency and other losses.

2. Suppose you have an inverter battery with a capacity of 150 Ah and an input voltage of 12 V, and you want to power three tube lights, three fans, and a Wi-Fi router using this battery. In this scenario, you may be wondering how long your appliances will run on this battery and what will be the battery backup time. To find out, let's calculate the backup time of your inverter battery and determine how long your devices will be powered.

Taking your inputs into consideration, you can calculate your total load, like:

• 3 tube lights = 40 x 3 = 120 Watts
• 3 fans = 75 x 3 = 225 Watts
• 1 Wi-Fi router = 1×20 Watts = 20 Watts

So, the total load in your case is 120 + 225 + 20 = 365 Watts.

Now, let us apply all these values in the above-said battery backup time formula. 

Backup Time (in hours) = 150 x 12 / 365 = 4.9

So, your inverter battery will last around 4.9 hours to keep your needed appliances running. 

 

Method 2: Using Battery Discharge Rate

The second method to calculate UPS/Inverter battery backup time is by using the battery discharge rate. The battery discharge rate is the rate at which the battery discharges during a power outage.

To calculate the backup time using this method, follow these steps:

Step 1:Determine the discharge rate of your battery. This information can usually be found on the battery or in the product manual.

Step 2:Determine the capacity of your battery. This is the same as step 1 in method 1.

Step 3: Calculate the backup time by dividing the capacity of the battery by the discharge rate.

For example, if the discharge rate of your battery is 10A, and the capacity of your battery is 100Ah, the backup time can be calculated as follows:

Backup time = battery capacity ÷ discharge rate

Backup time = 100Ah ÷ 10A

Backup time = 10 hours

 

Calculating UPS/Inverter battery backup time is essential to ensure uninterrupted power supply during emergencies. The two methods discussed in this blog, using battery capacity and load wattage, and using runtime provided by the manufacturer, can help you determine the backup time of your UPS/Inverter accurately. It's important to keep in mind that backup time can vary depending on several factors, such as battery age, temperature, and load type. Therefore, it's recommended to test your UPS/Inverter regularly to ensure optimal performance during power outages.
