I purchased this inverter. It is give us good power. And automatic transmission from main to load. It is saves more power and energy. Its life time is more. After replacing to this inverter our electricity bill was so less. That is why I am promoted this product.
But some time it shows small voltage fluctuations. And also this inverter has fuse externally. that is secure our wirings, bulbs, fans, and tubes
we are not know when the main supply is off. and comes electricity.
