Luminous is very popular and well known for inverters and for UPS. It is most trustable company. We are using this inverter from three years. And never face any problem with it.
This UPS has very long term capacity evern it continuosly works ten hours with fans and lights. I watch televion on this sometime. it takes up full load and never give problem.
For me this is the king of all othere batteries and inverters. Customer service by luminous is excellent too. The immediate respond and solve problem within less time.
