i don't think so,since the backup time is depending on the batteries you have in UPS, we should know how many pcs and capacity of battery you have for 1.5kva , let's assume 36vdc,7ah, the backup time should be :<500/0.9*10.5*3 > /7 = 2.5,2.5 is the discharge rate, so the backup time is 10 mins around,
