Solar power for 850 households in Mali

"Our AC-coupled off-grid solutions not only supply homes with electricity, but also contribute significantly to local creation of added value," said Volker Wachenfeld, Executive Vice President Off-Grid Solutions at SMA. Along with private households, a school, workshops, a bakery, a hotel and other shops are connected to the off-grid system. "That's especially important to us, because only strengthening the local economy will make the residents of the village truly self-sufficient," Wachenfeld said. "This is the only way to make rural electrification really sustainable."

In rural regions of Africa, off-grid systems based on solar energy are the most economical way to supply energy. Here, often less than one percent of the population has access to the power distribution grid. SMA multicluster technology is the ideal solution for simple and modular design of large off-grid and hybrid systems with outputs of 30 to 300 kilowatts. The completely preconfigured system allows operation and maintenance to be performed by locally trained service staff. If additional diesel generators are connected, these add to the electricity supply if insufficient renewable energy is available, or they load the batteries.

The company Asantys Systems (based in Heidelberg, Germany) installed the turnkey plants in Mali within just seven months. SMA supplied the electric system components, the Sunny Island off-grid inverters, the Sunny Mini Central solar inverters and the Multicluster Boxes. The PV modules were delivered from Centrosolar in Hamburg, Germany, and the stationary batteries were provided by Hoppecke in Brilon, Germany. The operator of the plant is the African FRES subsidiary company Yeelen Kura; maintenance will be taken care of by Asantys Systems for a period of five years.
