We use Luminous Inverter and UPS for last 2-3 years and we are pretty happy with durability and well functioning of both product.
Earlier we were a bit hesitant to buy any product of Luminous as it was quite new to us, but after recommendation of a family friend.
We purchased Luminous products and found them pretty useful and good in quality.No doubt buying Luminous Inverter and UPS pays off real value of your money.!
