I had purchased "Luminous Zelio 1100 Sine Wave Home UPS" in month of May. It is giving problem from last 2 months. Shows the status old- overloaded, when there is zero load. Sometimes, restarting UPS solve problem but not everytime.
I cannot use my mixer, which is of wattage of 750. Because if I try to use it. UPS get shutdown. I already raised complaint(4002733164) about that. The complaint resolution was increase battery from 1 pc of 150 AH to 2 pcs. Which is totally unacceptable. But still I have stopped using mixer.
But I am frustrated now with random behavior of UPS. It gives backup sometimes. I want a UPS, which can work perfectly everytime. I have microtek inverter in hometow from 6 yr, it gives such problems.
Please DONT go for this.
Go for microtek a trusted brand.
Update: After replacing the required parts, it started working fine for me.
