The inverter is working fine so far, but the service is pathetic. I bought the inverter from Sapna Electronics - Mulund (West) Mumbai. Before buying they promised a lot of things about service. They mainly said that we just need to call them and they will send the company person for service.
One year service is free and the person is supposed to visit every quarter. The problem is Sapna Electronics never sticks to their promises. One of my friend had a similar issue with Sapna. As per their promise the service was supposed to be free for one year, but when the service person came, he was not even ready to touch the inverter until I paid him good amount of money.
 
Overall the inverter is fine, but Sapna Electronics sucks and Luminous service is pretty pathetic. Therefore if you are person who believe that after sales service is an important factor, please do not go for Luminous. That too never buy it from Sapna if you are a Mumbai resident. Advise your friends as well.
 
Sapna Electronics sucks. Sapna Electronics sucks. Sapna Electronics sucks. Sapna Electronics sucks.

They are spoiling Luminous name.
