US-based producer of saltwater batteries and energy storage systems, Aquion Energy, Inc., is helping South Africa power its Kruger National Park. The firm recently installed an off-grid micro-grid at a nature lodge in the national park.
The micro-grid consists of a 55-kWh Aquion Aspen battery bank, paired with a 10-kW solar array.
The solar array and Aquion's Aspen batteries provide full power for the camp, which consists of four luxury tents, a central lounge, swimming pool, and a water pressure pump for drinking water. The batteries have been sized to comfortably support the site's loads during overcast conditions before getting assistance from a back-up diesel generator.
The system was designed, installed, and integrated by Solarsun Solutions (Pty) Ltd. with support from Cape town-based Solar World Africa (Pty) Ltd.
