My neighbors bought a microtech inverter 50 days back the system started giving problems.All the points connected to the inverter went off.Neighbors purchased the unit from pal auto electricals in dabra contacted him he said to contact the toll free number neighbor tried several times but no one received his call.Then neighbors had to contact him again then he gave his another local number but the person received my call in line.It is sheer disgusting.thats by I give 1 star for this type of customer service.
