We are using Luminous Inverter in our home from past 6 years. Inverters are a basic need in residents to avoid any power cut between an important works. We are using this brand and pretty much satisfied,
I don’t know much of its specifications, but I am sharing my real experience. It recharges very fast, we are able to use three fans and two tube lights for continuous 10 hours on inverter back up. It gives pretty well back up without any discontinuity. Its weight is around 10 Kg, It is of 875 VA, We have not changed its battery till date which is the bestest part of it, main cost is of battery, we often notice, that batteries need to be changes after 2 years though warranty is of 5 years, but quality of batteries are not that good. Battery is unleaded and eco friendly.
If I compare it with Su-Kam, then it is far better that this. Su-Kam need repair and maintenance and gets discharged in just 5-6 hours. I recommend luminous inverter only
