Hello friends, I brought GENUS SURE SINE WAVE INVERTER from a local shop.but my experience with it is not good.the main problems of this inverter is not proper in sense of the design and look.only 4 months it worked properly but after this have problems many times.the durability of this product is too poor quality and not proper in the sense of the working condition. Battery quality is too worst. After few months, it not capable to give power even for two tubelights for 3 hours. If you on one tubelight and one fan, after 1 hours it showing alert sounds. Device is not user friendly and performance of it not ok.worst point of this inverter that it has short circuit problem. 1st time it was repaired free of cost by company.but from 2nd time they charged extra money.so I replace it.
