I am using microtek inverter since 1 year and I am facing many problem from this inverter and I have repaired 10 times and it damages again and again. The worst inverter I have ever buyed in my life better than this you can buy other company inverter. Its just wasting of money and there is zero percent durability and power so I specially suggest you all people to dont buy this bad inverter. And also the price is also too high that you cant afford so better dont take and waste your precious money.
