The new DC generator has been described as a ‘game-changer’ thanks to its lower capital and operating costs compared to AC systems, combined with advanced features and superior fuel efficiency.
The cost of powering off-grid cell sites is one of the main factors holding back the roll-out of telecoms services into developing countries. This has a major impact on economic growth in those countries – and on the provision of vital services such as health and education.
More than a million of the world’s cell sites run on generators all or part of the time. Most rely on more expensive AC generators, with relatively high fuel consumption, which makes them unpopular with environmental campaigners and this leads to reputational damage for the telecoms companies – as well as higher costs.
A new product launched by Controllis, a UK-based DC generator and control systems manufacturer, has the potential to transform the efficiency of supplying power to off-grid cells.
The Controllis Basic48-10 is a high efficiency 48V, 10KW DC generator designed specifically to power off-grid telecoms sites. It is cheaper both to run and buy than a traditional AC system. It also uses less fuel and so reduces the carbon footprint.
Controllis CEO Simon Albury says:
He says the breakthrough pricing has been achieved through a series of engineering and technical improvements.
DC generators offer the additional benefit of seamless integration with renewable solutions such as solar and wind power.
The Controllis Basic48-10 is being made available globally from 9 March 2016.
