I bought microtek inverter in march 2016 and very satisfied with service. It takes less power to charge battery long battery backup. I lives in U.P where electricity is less than 14 hours a day. Then I bought microtek inverter and electricity problem solved completely. Now my home is always lighting. It take less time to charge the battery. My mother is used it without any fear of current. It is very safe and most important service is very good.
Sorry for my bad english.
I think it will be helpful.
