How to calculate the inverter requirement
'''Battery backup duration'''
Here we have an equation to find the battery life on load
Time(in Hrs) = Battery Voltage (In volts) * Battery Capacity (in Ah)*efficiency of inverter
Load (in VA)
Let us have a sample calculation
Battery voltage = 12 Volts
Battery Capacity = 150 Ah
Load = Two fluorescent lamps (40 Watts each) and one ceiling fan (75 Watts )= 155 Watts
Inverter efficiency = 80%= 0.8
Backup Time = 12 * 150*0.8/155= '''9.29 Hrs''' (Approx)
