Solar Battery

BBN has launched its solar flooded tubular monobloc batteries  and designed to offer reliable, consistent and low maintenance power for renewable energy requirements.

BBN has also developed a 2- volt range of tubular batteries from 200Ah to 600Ah for solar photovoltaic applications having a design life of ten years plus. However, the life of the battery is dependent on the ambient temperatures and the number of times it is cycled and the depth of discharge.

These solar batteries have been developed keeping in mind the various parameters peculiar to India by a team of experts. Our batteries are designed to give long life in cyclic operations and extremely long intervals in topping up and even total freedom from maintenance.

While, our batteries are approved by MNRE, BBN Solution continues to experiment with new and improved alloys and manufacturing technologies to enhance the life of our solar batteries, reduce topping up, etc.
