Luminous Zelio+ 1700 Pure Sine Wave 1500VA/ 24V Inverter supports 2 Battery each of 12V for Home, Office and Shops

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.

The media could not be loaded. So far so good after two months of used.Good control of battery and its management, there’s fan sound definitely so put at least not where you can be disturbed.

Veru good product and working awesome. I like the design and lcd display. It shows battery level and backups Time depending on The load.I have a small problem with this exhaust fan it produces more humming sound while charging time and lcd display shows 5 minutes to full charge but it is taking 2 to 3 hours in that times suddenly exhaust Fan off and on. And one more thing is inverter terminal wires are little bit short . Other then overall it’s good Inverter i will update my comment with future usage

Wrost Product Ever and Wrost Customer Care Support.

Liked the product, it has a display which will take some time to get used to it as we earlier had older Luminous inverter which had indicatorsDoes the work well, seamlessly switches to battery and vice versa

After 2 weeks review i can say it is overall a good package, it is super fast while switching to battery after power cut, can run around 600watt loan.. Yess it make decent amount of noise while charging due to fan.. build quality is good and sturdy .. loved the LED screen it shows charging time and discharge hours which is nice for long power cuts.. charging speed felt little slow but not much issue. Its value for money product... The thing i dont like is it had came with broken warranty seal so i had to contact different customer care to resolve and yes service centre response quickly and were ready to come to home for sny repair.They said broken seal makes no difference in warranty.You can go with this product and luminous cam be trusted.

It was one of the best purchase from Amazon. The specifications and working of the inverter is perfect. Bas isko laga data to tension jhingalala...highly recommend 👍

Product may be good, but don't trust this seller at all. After about one and half year of purchase, when it broke down, the local mechanic who came to repair told me that many parts of the inverter were changed and desi parts were fitted in it. It was also confirmed by the authorised service provider. I had to get those desi parts changed with original parts of the company and thereafter it is working properly.
