My neighbour was purchased this inverter before 2 momths but he and his family got irritated for 2months due to its bad performance.
It was charged fully but its backup was very bad, it hardly runs about 4-5 hours.It was heavier as compared to other inverters in this price range.It costs high as far as its performance was concern.As their are many good inverters available in the market in this price range.
So, in my opinion , you should not purchase this item.
Thankyou very much.
