I am a resident of Delhi and in the summers the power cuts are a very big problem, keeping this in mind along with the really high temperatures of Delhi I needed an inverter that could provide long back ups and could also could keep the refrigerator running. On the recommendation of the salesman I went for the Su-Kams pure sine wave inverter.
After using the product for one year, I am really satisfied with it. It provides uninterrupted power and can also run the refrigerator. An added advantage is that it also acts as an UPS for my computer. This truly is an amazing product.
