In my house six years Microtek UPS - E2 inverter is being used. According to me it is one of India's best Inverter system, which is not very expensive and also very easy to use can be brought. It's look is very good. The digital notification light is predicted to ease current power and charging. The Microtek UPS - E2 to connection can be done easily at home. And, most important, that it takes longer to charge the battery as soon as the current product does. Inverter for many years once it is purchased.
