I would like to draw the attention of how poor service he provide. I have microtek inverter few months before. After few months my inverter was not working properly. Some time different type of sound came and some times the inverter switch off automatically. After few weeks inverter had stopped permanently. I complained the customer toll free number. I filled a complain and he said seven working day my engineer will be visit at your place, but seven day no engineer came and again I complained and same answer he asked. I think it happend almost four times. Finally I visited local mecahnic for repairing my inverter. The service is very poor.
