This UPS shows a very good Droop voltage, well above the limit. The float voltage at 2.30 V DC per cell is a very good sign in terms of battery life. It comes with control software. Though its minimum output voltage to the load is fine at 185 V, it should be a little higher. It has a low backup time of a minute and half at 80 percent of its rated load. The UPS is not able to do a cold start.
