The new product of the US-company Aquion Energy is designed for energy-intensive applications that use solar panels, such as off-grid solar-powered LED lighting, as well as small pumps and motors. It is also an ideal drop-in replacement for existing systems using 24-volt lead-acid batteries.
More than 700 Aspen 24S batteries are already operating in a demanding field environment in Thailand. In the first quarter of 2016, Aquion completed an installation at Bangkok International Airport’s Sky Lane bicycle track. The project successfully demonstrates the 24-volt battery under real-use autonomous conditions, connected to solar panels and energy-efficient LED lighting. The Aspen 24S was a good fit for this application’s requirements because it delivers long cycle life, deep cycling capability, and robust performance in high ambient temperatures and partial state of charge cycling conditions.
Traditionally, off-grid renewable energy systems that include energy storage have used lead-acid batteries, known for their toxicity and relatively short lifespan under deep cycling and partial state of charge usage – a common profile with solar-based systems. Aquion’s Aspen batteries have an environmentally friendly electrochemical design, and are the first and only batteries in the world to be Cradle to Cradle Certified.
