As most of us know that microtek is pioneer in inverter industry. I have been using two microtek inverters since last ten years. these are versatile. maintenence free. I am fully satisfied with the brand. these are easy to use and now a days microtek inverter comes with battery water level indicator so no need to check battery water level at regularly. when the water level becomes low a red light indicator is turned on on front panel so that you can top up battery water. this is really a good feature.
