A UPS has two ratings and the lower one is the limit. This unit is rated 50 kVA and 50 kW, so the equipment plugged into its battery outlets should draw no more than about 40 kW if you want the usual 20% headroom. How to size a UPS.
Its weighted efficiency of 96.3% compares with a median of 96.2% across 40 certified units within 25% of its capacity. With nothing plugged in it still draws 349.2 W, about $398 a year at 13¢/kWh just to stand ready.
