OMG there is no word about the luminous on its durability. It is one of the best products that I bought. And it’s one of the most attractive specialiarity is that.it is eco-friendly. I’m using luminous inverter is about 4-5 years and it is completely well till date. If we compare it through another inverter then we found a lots of difference from other like luminous is cheaper, it is eco-friendly, it works more years compare to other, it’s warranty duration is also more and many more. So in my opinion luminous is best inverter in cheaper prise. Thank you.
