Microtek is one of the most popular brand inverter in market.It is very costly, I use microtek since 5 Years. The quality is very poor. It has no life, it is a expensive or loss of money, it has many problems.
Performance wise this inverter is very poor. No efficient battery back-up come with this inverter, Literally spent of money unnecessary. It is not giving back-up of power more than 2-3 hrs, made a complaint to the company, no response. after 3 to 4 battery will be damage and you have to purchase a new battery worth Rs.12000/-.
This inverter is not so useful for giving better output, I am not like this inverter. It is not saving electricity and not gives better output. I do not suggest to purchases this inverter.
