Answer Posted / p. gupta
in case of offline ups power is processed(step down or up to maintain specified voltage level and filtered) and fed to the load , in case of mains failure power is supplied by inverter
while in case of online ups inverter is always on to supply power to load. power from mains and inverter is synchronized and fed to load
