I bought microtek inverter 6 months ago.This invertor really sucks.At the time when I went to buy it the seller tells me a lot of good points about this products which are countless and I think he forgets to tell me about the bad points.No worry, I will tell the bad points.So, the first bad point is the battery backup, the company claims 6-8 hours minimum but the inverter doen’t last more than 4 to 5 hours.The invertor is really bulky and the battery is quite big.This microtek inverter produces so much noise.The performance if this invertor is also very bad.I use 7 led bulbs and 3 fans then only the light in the inverter starts blinking it cant handle that much of load.And the worst part is it takes more time to charge and doesnt even provide that much battery backup.At this price point there are so many good invertors in the market which provides better performance and satisfies customer to the extent.So from my point of view this inverter is waste of time.
