How To Calculate Ups Battery Run Time. If you have a setup that. Battery Run Time Example.
For example say you want to run a 250 watt 110VAC light bulb from an inverter. A battery run time is the total time in hours that a battery can sustain a certain power output. Backup Time in hours Battery Capacity in Ah X Input voltage V Total Load in Watts.
10 x battery capacity in amp hours divided by appliance load in watts.
Battery Runtime Available Estimate 10 x Battery Ah load Watts runtime available. For example say you want to run a 250 watt 110VAC light bulb from an inverter. 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. Create a base ratio from available AH.
