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.
FAQ- About - 150ah Battery Backup Time Calculator Saudi Arabia
How many hours is a 150Ah battery backup?
Now, in the last stage, let's put all of these values into the formula. Backup Time (Hours) = 150 x 12/290 = 6.2 (approx.) As a result, in this situation, the 150Ah battery backup duration is around 6.2 hours, implying that it can power your gadgets for 6.2 hours once completely charged.
How do I calculate battery backup time?
How do you calculate battery backup hours? Backup time of UPS (in hours) = [ Battery rating (in Ah) × Battery rating (in V) × Number of Batteries × Battery Efficiency ] / Load in Watts (W). Therefore, with a load of 500W, the 2kVA will last for 0.75168 hours ( approximately 45 minutes ).
What is the difference between 150Ah and 200Ah battery backup time?
Comparing 150Ah and 200Ah Batteries: a. Backup Duration: A 200Ah battery generally provides a longer backup time compared to a 150Ah battery. The extra capacity allows it to power more appliances or devices for an extended period during a power outage.
How much unit does 150Ah battery consume?
How many watt hours is 150Ah? And the amount of power stored in a 12V, 150Ah battery will be 12V x 150Ah = 1800Watt-hour (1.8kWh). What is the charging current of 150 Ah battery? It has Charging Current capacity of 0.3 C (rated capacity at 10 hours) Amps with a charging voltage of 13.5 V.
Can a 150Ah battery run a fridge?
A 150Ah battery can power many home appliances at once. This includes fans, lights, and your Wi-Fi router. It can also run a TV and small refrigerators if they don't use too much power.
What is normal battery backup time?
All you need to know are a few parameters and you are good to go. The UPS backup time depends on the power consumption of the UPS, the power of the load, and the battery capacity. In general, you can expect your inverter battery to last anywhere around 5 to 10 hours when it is fully charged.
What is the formula for battery time?
The calculator applies the formula: Capacity (Ah) x Voltage (V) x Efficiency / Load Power (W). This equation gives an estimated runtime based on the input values. For instance, a 100 Ah battery at 12V with 90% efficiency powering a 50W load would have a runtime of (100 Ah x 12V x 0.9) / 50W = 21.6 hours.
