ups uninterruptible power supply time calculation

system voltage = volt

equipment device voltage and current
load 1 = wattinstall
load 2 = wattinstall
load 3 = wattinstall
load 4 = wattinstall
load 5 = wattinstall
load 6 = wattinstall
load 7 = wattinstall
load 8 = wattinstall
load 9 = wattinstall
load 10 = wattinstall
