I bought luminous battery and inverter 4 years ago and after some months the inverter got some problems and we got it repaired. Even after repairing, the inverter was not back good. After some more time the inverter started creating some sound like some one hit it by stick. The battery was the luminous invergold and it was also damaged 5 months ago at the time I am writing this review. Luminous needs to work on their service and products, both.
