Luminous Zelio+ 1100 Pure Sinewave 900VA/12V Inverter for Home, Office and Shop (supports 1 inverter battery of 12V)

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

Excellent inverter for home use. Using Luminous Zelio+ 1100 with a 200Ah battery and getting reliable backup. Overall, very satisfied with the purchase. Highly recommended!

I recently purchased a Luminous inverter, and my experience with it has been nothing short of frustrating. Here’s a breakdown of the issues I faced: First Week Issues: After just one week of using the inverter, the fan stopped working. Not only that, but the inverter started overheating, producing a strange noise, and eventually shutting down. I immediately contacted customer service, and they sent someone to fix it. However, this meant I couldn’t use the inverter for a significant period during an important time, which was very inconvenient. Second Issue - Electric Shock and Grounding Problem: A month later, I faced another serious issue. The inverter started returning ground and delivering electric shocks throughout my entire home. I contacted an electrician, and after some investigation, it was determined that the inverter was the cause. I raised another request with the company, and a technician came to fix it. The technician tried everything, but after bringing in a senior technician, they still couldn’t resolve the problem. Unresolved Issues and Poor Customer Support: At this point, I requested a replacement product, but they refused. Instead, they suggested replacing the transformer, which didn’t solve the root cause of the issue. My main concern is that I purchased this product for its supposed reliability, but now it’s just sitting idle in my home, still malfunctioning. Conclusion: In short, I feel completely let down by Luminous. The product has been faulty since day one, and their support has done little to resolve the ongoing issues. I regret purchasing this inverter, and based on my experience, I would not recommend it to anyone. It’s frustrating to invest in a product that doesn’t live up to its promises, and the lack of proper customer service has made the experience worse. Rating: 1/5 Recommendation: Stay away from this brand, as it seems like quality and customer care are not their priority.

The Luminous Zelio+ 1100 is a good inverter for providing backup power during frequent power cuts. The pure sine wave output makes it suitable for common household appliances and electronic devices. The 900VA capacity is sufficient for essential loads such as lights, fans, Wi-Fi router, TV and other everyday appliances, depending on the battery and total connected load. It supports a single 12V inverter battery, which keeps the setup relatively simple. The inverter has a compact and clean design and feels well suited for home, office or small-shop use. Installation and battery selection should be done according to the required load for getting the best backup performance. Overall, a dependable option for regular power backup with pure sine wave technology and good capacity for essential household needs.

Purchased two,one is 2018 and second one in 2023. First one still working fine. Second one failed after two and half years. Dont accept to card replacement for repair if technician recommends. It will be waste as it happened.

I've bought this item on 8th July 2021. Paired it with a single 140 kv (or something something) tubular battery and used it with ups mode on nine 25 watts tubelight, 1 55inch lg tv, and one desktop pc with 650watts SMPS/psu (with rtx 4070, lasted around 3 hours of gaming with the tv on and 3 or 4 tubelights). Working fine till now on 3rd July' 2026 without any problem so far. Will definitely buy it again if required. Hoping I don't jinx myself with this review. With pc and tv off, the display says 9:59 more hours, as more than that is not supported by the display.

When first connecting this inverter, the fan ran every ten minutes for about 75 seconds at full speed, and it hummed very loudly. Fortunately, that stopped after three hours or so, and now the fan turns on a few times a day for ten seconds (it's summer and the temperature where it is 25C or so.) I don't hear much hum any more, but I wish they had told me that as I was close to turning it off and returning it. Since then, it seems to work, although I haven't been able to calibrate the timer. I guess you have to run the battery down to zero which I don't want to do, partly because it's bad for the battery and partly because it says it will give a loud alert sound. Also, the battery liquid tester function requires extra hardware which was not mentioned.
