Hi, I am writing this review after using this inverter since last 10 days. This Inverter has many features like fast charging and normal charging switch, short circuit protection, ups and inverter mode switch. Its power output is sine wave which means there is no noise etc of fan which is there in square wave inverters and the price is slightly more than square wave inverters in same capacity. This device has multi stage charging which ensures longer battery life and tricle charging mode to top up charge the battery for maximum backup during long power cuts. And last not the least the brand microtek has the best service network across India and their service is very good. This is full bang for your buck no second thoughts simply go for it.
