Back up time battery power in watt hour wh connected load in watts w battery power in wh battery capacity in ah x battery voltage v x number of batteries.
N number of 12 v batteries needed.
When the battery backup time is 3 5h k 0 8.
Back up time of inverter battery battery voltxbattery ah rating total watts on load.
When the battery backup time is 3h k 0 6.
Backup time battery ah x 12v x n x efficiency of battery load in watts.
Inverter battery backup time is calculated as.
1 ceiling fan 75 watts.
In order to calculate the battery backup time multiply the battery size in ah by the number of batteries needed by battery voltage usually 12v by battery efficiency rate usually 0 80 then divide your answer by your power load in watts.
For calculating inverter ups back up time follow these formula.
