Today I am sharing my experiance with luminous inverter. I am using this inverter last 2 and 1/2 years and I must say its best inverter cause I did not faced any issues. I purchased this because I have many room approx 5-6 rooms which needs electricity when main electricity gone. It provide me upto 13-16 hours of battery backup with common uses. I have used tvs, fans amd lights in uses.This works really well and takes lot of time to charge cause its a big inverter.
