Battery Backup Time Calculator Formula

How to calculate battery runtimes.

Battery backup time calculator formula. 1 ceiling fan 75 watts. The load calculator displays the ideal inverter battery combo for your home or commercial establishments. Check theinverter and battery price list before choosing a large or small inverter battery according to your specific needs. The formula generally used is 10 x the capacity of the batter in amp hour divided by the load of the device in watts.

Back up time of inverter battery battery volt x battery ah rating total watts on load so if a person use 1 ceiling fan 1 tube light 2 15watts cfl simultaneously with 150 ah battery then the backup time will be calculated as. If your using the inverter of 600va it takes the load of 450va for example with losses considerations 12vx10a 120w multiply into 4 for 4hours full load concept then loads like 2fan 4tube light example 120ah. Formula to calculate the back up time of inverter battery. Ups backup battery ah volts load 1 power factor example.

Power factor of home standard. Calculate the estimated run time or battery backup time of specific battery backup power inc. This is the formula that is commonly used to calculate battery run time. Backup time battery ah x 12v x n x efficiency of battery load in watts.

Luminous has a comprehensive range of inverter and batteries to fulfill your power backup requirement. 1 tube light. The battery backup will only vary depending on the battery ah and the usage load. To calculate ups backup we have a simple formula.

Very often consumers will opt for a lower cost quote on a backup system. Ups uninterruptible power supply models using the load in watts and the model configuration drop down. Although there is seldom a 100 efficiency factor when hooking up a battery with a device the formula below will be based on this case scenario. However the one thing that consumers consistently fail to understand is battery sizing for backup power systems.

This purely depends up on the load. Let us calculate the backup for a system ups load is the usage power suppose we are running a. The ups wattage the battery backup will not vary. The battery backup time in hours can be calculated using following formula.

Where battery ah ampere hour capacity of battery n number of 12 v batteries needed efficiency of battery generally it is 0 8 which is the max.
