150AH battery backup time how to calculate

If you use an inverter system, we are confident that you are already aware of the various benefits it provides. Now, you should have enough knowledge to choose the best one such as the one from Daewoo India for your home. Unfortunately, when it comes to inverter batteries, most of us depend on the salesperson’s comments rather than doing our research.   

Have you noticed that your inverter battery backup isn’t lasting as long as it should? So don’t worry. In this post, you will discover how to calculate 150Ah battery backup time, as well as some ideas for increasing the backup duration of your inverter battery.   

How Do I Calculate 150Ah Battery Backup Time?

Calculating the backup period of an inverter/UPS battery is straightforward. You only need to be aware of a few aspects that affect the 150Ah battery backup duration. These metrics include power consumption, load power, and battery capacity.   

An inverter battery from brands such as Daewoo Electricals lasts between 5 and 10 hours when completely charged. However, using the technique below, you can compute the correct 15Ah battery backup duration.  

Backup time (hours) = battery capacity (Ah) * input voltage (V) / total load (watts). 

Consider the following hypothetical situation: you have a 150Ah inverter battery with a 12V input. Assume you wish to power two fans, two tube lights, and one Wi-Fi router using the inverter battery. Let’s use the calculation to determine how long your appliances can operate in this case.  

Two fans = 75 * 2 = 150 watts.  

Three lights = 40 * 3 = 120 watts.  

1 Wi-Fi router equals 1 * 20 = 20 Watts.  

Therefore, the sum total of the load in your situation is 150 + 120 + 20 = 290 watts.  

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 does battery capacity affect inverter backup time?

Let’s maintain all of the values the same as before, with the exception of the battery capacity, and see how it affects the pure sine wave or hybrid solar inverter battery backup time.  

  1. In case the battery capacity is 110Ah

Backup time: 110 x 12/290 = 4.5 hours (approx.)  

As a result, if your inverter battery capacity is 110Ah, you will have a 4.5-hour battery backup time.  

Ii. If the battery capacity is 220Ah, the backup duration is approximately 9.1 hours (220 x 12/290).  

In this circumstance, your inverter battery can keep your appliances running for 9.1 hours.  

These two instances demonstrate that the capacity of your battery has a major impact on its backup time. That example, the bigger the battery capacity, the longer the battery backup time will be.  

How Can You Increase Your 150Ah Battery Backup Time?

Here are four strategies to enhance your power backup UPS system, hybrid or pure sine wave inverter:  

  1. Avoid Rusting and Corrosion.

Because corrosion degrades the performance of your inverter battery by limiting current flow, it is critical to keep it free of rust and corrosion at all times.   

  1. Don’t overload.

If your inverter battery becomes overwhelmed during a power outage, your backup time will be reduced. As a result, it is best to disconnect any gadgets that are not required immediately but are consuming a significant amount of energy.   

  1. Use energy-saving gadgets.

Using energy-saving equipment can be an excellent way to cut power use. For example, using LED bulbs instead of classic tube lights or bulbs saves over 75% on electricity use. 

  1. Check the Water Level.

Check the water level in your inverter batteries every two months. It is important to note that the water level should remain within the minimum and maximum limitations. Furthermore, avoid using tap water since it includes pollutants that may impair the operation of your batteries.  If you’re searching for an efficient inverter battery to power your gadgets, check out our best-in-class assortment, which is specifically intended for extended and frequent power outages.
