Nothing more to say, all said above is the best you can get from power soft ,avoid these guys .
These jerks installed inverters at my place and never bothered to check it in spite of calling them multiple times.
Best part they installed a battery called M power tubular battery ,its scrapped now ,I am trying to find a dealer in Bangalore I am not even able to trace even a single one. Can anyone give any information on these batteries so I can replace myself .its still under warranty
