Microtek inverter is not good at all after some days of use it will unable to flow current to a 100 watt bulb too.I had a 750 watt microtek inverter and after 11 months use it was unable to light up a 100 watt bulb, when I went to the shop to repair by warranty they take money from me even if I had it's original bill and warranty card, they refused to accept it.so their customwr service is not good at all.After the repair it works finely for another 4 month but soon after that it was not charged at all even I plugged in tje pin for all the day but it does not recieved.Not at all a durable product.Don't buy it.Just waste of money.Thanks
