Answer Posted / k.prakashchandra
Back up time is dependent on storage capacity of
battery.vxAH=stored energy in watt hours. Divide this by
load in watts to get back up time in hours.If the batteries
are in parallel add up AH.If in series, AH of one battery is
to be considered adding voltages. Use identical batteries.
