Solar Luminous Tubular Batteries

Luminous has launched its solar flooded tubular monobloc batteries designed to offer reliable, consistent and low maintenance power for renewable energy requirements. These batteries can be subject to deep cycle applications and minimum maintenance in rural and power deficit areas. The batteries have a capacity to withstand partial state of charge (PSOC) operation. These monobloc batteries are available in 12 Volts from 20Ah to 200 Ah @ C10 at 27?C to 1.80 vpc.
Luminous has also developed a 2- volt range of tubular batteries from 200Ah to 1000Ah 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 scientist and engineers at a R&D facility dedicated to electrochemical research at our works in Gagret, Himachal Pradesh.
Luminous decided to develop these solar batteries keeping in mind the increased awareness and public spending in the field of new and renewable energy for applications in household lighting, street lighting and in rural and urban cellular telecom installations. We expect a significant shift in the telecom industry towards use on non-conventional energy due to increased operational expenses. Increased government incentives and subsidies will, in the next couple years, lead to increased spending by governmental agencies in the new and renewable energy.
Our batteries are designed to give long life in cyclic operations and extremely long intervals in topping up and even total freedom from maintenance. Our batteries can be adapted to use auto-fill systems and air agitation systems for faster charging and avoidance of acid stratification in standby cells. For outdoor applications, we offer batteries in IP55 enclosures.
While, our batteries are approved by MNRE, Luminous continues to experiment with new and improved alloys and manufacturing technologies to enhance the life of our solar batteries, reduce topping up, etc.
