Connections were easy. Connected the battery with the right terminals, chose the correct battery type (Tubular in my Case) and chose the mode I wanted (UPS in my case and not eco since I wanted the UPS to cut off earlier with even slight voltage variation). Made sure that the MCB behind the UPS was on and also the switch was set to Normal. The UPS started functioning perfectly. I purchased the battery from a local vendor as he provided better prices (also for the return of my old battery).The UPS takes about a minute to recognize the battery level. This happens only the first time you connect the battery. It will take some time to recognize the battery capacity every time you disconnect and reconnect the battery and in most cases, I guess people hardly do this once in 3 or 4 years to replace the battery.The screen is informative. Shows a power icon when mains are connected. Shows Eco logo if it is set to eco mode and no logo in UPS mode. It shows the battery type when you change the type behind the UPS. When the UPS is on battery, the timer shows the approximate battery life in hours and minutes. If the battery is being charged, the UPS shows the time left for a full charge in hours and minutes. 2 downsides: If you have a high capacity battery and no load or low load (say just 2 or 3 LEDs) then the display shows the maximum 9 hours and 59 minutes since the display has no more space to show time beyond 9:59. The second downside is that the fan makes a significant amount of noise while the battery is charging and also generates quite a lot of heat. Avoid placing it in the living room or close to your bedroom.The UPS does come with an option that gives you the battery distilled water level indicator. The downside is that most vendors do not have this in stock (Luminous E-Float Magnetic Water Level Sensor, as far as I remember).The other issue I faced was the error codes. It was late at night and my light switch was not working. I decided to change it myself as I had a spare. I was working with the electricity on and accidentally did something to trip the breaker. My breaker tripped, I turned it back on. But the UPS was running on battery even when there was electricity available. The screen showed an error code like B01 if I remember. I did not have the manual handy and did not get any results when I googled the code. I then planned to remove the UPS and connect the mains directly, that's when I found that the UPS breaker had tripped as well. A simple breaker reset solved the problem.The last thing on my mind was the input wire size. I spent quite a lot for home wiring and have used wires with thickness of 4 sq. mm for lighting circuits as well. The wire that carries the load of all light, fans and electronic devices passes through a very thin wire provided by the manufacturer. I always have the concern that an overload may burn that wire even before the breaker trips. Maybe all manufacturers have this practice. The wires provided in 2000W water heater or an A/C unit are very thin as well and I am just a little paranoid.

I think i got a return product... bcoz the cover is torn..and.. on the box was written by pen like amazon return.that is the one thing i hate..but product works properly..the display is good for us..we know what backup time and charging time that is helpful

Great product. Excellent inverter for home use. Overall satisfied with the purchase.

Don’t go for it. I have bought it on May 2026 and so far (Oct 2026) 2 times board got crashed. Also, due to poor service network , it takes almost a week to get it resolved.Totally wasting money, time and mental stress.
