What is 200ah Battery Backup Time & How Can You Calculate it?

With the ever-increasing population, it is difficult for power sector companies to provide uninterrupted power supplies.Since there is so much to deal with, nobody has the time or patience to wait for the grid power to be restored. That’s whymost homes & offices are now getting inverters for constant supply to get comfort & safeguarding their appliances from getting damaged. 

However, the ability to compute inverter load and backup duration is quite uncommon. But we must know everything before buying the inverter for home or office. So, the next question would be What is 200ah Battery Backup Time & How Can You Calculate it? Most customers frequently ask the salesperson this question and rely on what they say. We believe that you should have some knowledge about the 200ah battery backup time of an inverter so that you make a sensible decision. 

You must understand that calculating the 200ah battery backup time of an inverter battery is not rocket science, but there are some important points to consider. The inverter battery backup depends on the power consumption of the inverter, the power of the load, and the battery capacity. Read on to know more! 

200ah Battery Backup Time: Things You Must Know

200 ah inverter battery backup time means that the inverter battery will provide a continuous current of 20A over the discharge period of 10 hours. Still, it is subject to the number of appliances you are using.  

 Here’s how we can easily calculate the 200Ah inverter battery backup with the following formula & example:  

Formula: Backup Time = C*V/W 

C = Capacity of the Battery in Ah.  

V = Input Voltage of the Battery 

W = Total Load of the Battery in Watts 

 For example: If your inverter has a 200ah battery with 12V input voltage. Now you want to calculate the battery backup of the inverter after using two fans, two tub lights, and one fridge. Following is your inverters backup:  

  1. 2 fans: 75*2 = 150 Watts 
  1. 2 tube lights: 40*2 = 80 Watts 
  1. 1 fridge: 120*1 = 120 Watts 

The total load for the same is = 350 Watts.  

Now, after applying the above-provided formula, the total backup will be:  

As we mentioned above, the formula – Backup time = C*V/W 

Therefore, 200*12/350 = 6.8 hours (Approx.) 

Finally, 6.8 hours is your inverter’s battery backup. In simple words, your battery will last 6.8 hours while running these appliances. This way, you can anticipate that the battery capacity of an inverter plays a vital role in the inverter backup. The more capacity, the greater will be the backup time.

Points to Improve the 200ah battery backup time

After calculating the battery backup of a 200 Ah inverter battery, you must know how to improve the backup time to ensure the inverter lasts longer during power outages. In general, the inverter lasts anywhere around 5 to 10 hours, but you must keep things efficient by following the points chimed in for you:     

  1. Reduce the load on the inverter, don’t attach heavy load appliances with the inverter. If the load is low, the backup time will be more.  
  1. Buy an inverter from a well-reputed and trustworthy company. A high-quality product will be power efficient. Luminous batteries have high quality, low heating, and more backup time.  
  1. You can also check whether the battery’s charging setting is accurate.  
  1. Get the right inverter as per your load requirements. For example, if your load is high and you are getting a low-capacity inverter, it will be difficult for the batteries to stand.  
  1. You can also compare between inverters as per the requirements you have.  

 200 Ah battery backup time or inverter’s battery backup is the most important quality you must ask the seller or have knowledge of. There will be many instances when you get low backup inverters if you buy an inverter from a local unauthorized seller.
