How to Calculate Inverter Battery Backup Time? Backup Time (in hours) = Battery Capacity (in Ah) X Input voltage (V) / Total Load (in Watts) Whenever you plan to buy an inverter battery, there is a desire to know some important information in your mind. Like how much will be the backup of the inverter battery, how many hours of backup will be available for how many ah batteries, etc. In this informative information, here you will know the backup time calculation formula. Taking your inputs, you can calculate your total load, like: 3 tube led lights = 40 x 3 = 120 Watts 2 fans = 75 x 2 = 150 Watts 1 Bulb router = 1×20 Watts = 20 Watts So, the total load in your case is 120 + 150 + 20 = 290 Watts. Now, let us apply all these values in the above-said battery backup time formula. Backup Time (in hours) = Battery Capacity (in Ah) X Input voltage (V) / Total Load (in Watts) Backup Time (in hours) = 150 x 12 / 290 = 6.2 So, your inverter battery will last around 6.2 hours ....
