The diesel generator has a power output of 150kVA and can be remotely controlled. Real-time monitoring and remote grid maintenance occur via VPN using a SCADA system. Additionally, the UPP offers access to historical data via the DHYBRID web portal.

AFD and Eskom commit to a competitive electricity sector Read moreNews on carbon emissions In addition to the new and quiet energy supply, the lodge uses custom-engineered electric vehicles for its safaris. A separate greywater recycling system, as well as a sewage treatment plant, have been installed on the property to minimise water consumption and environmental impact. A diesel generator, integrated with the microgrid, is available for use during low irradiation periods to support the storage system. DHYBRID’s Universal Power Platform (UPP) monitors and controls all the components in the system and therefore ensures a reliable energy supply at any time. Low carbon, solar future could increase jobs in the future – SAPVIA Technical specifications of the installation The grid-forming, bi-directional battery inverter with a power output of 250kW is supplied by the lithium-ion storage system, which comprises Samsung SDI cells and offers a capacity of 1,027kWh.

The new electricity supplyoffers a three-phase power output and comprises three solar installations witha total capacity of 300kWp; comprising a 160kWp rooftop installation, 100kWpmounted on carports, and 40kWp on dual-axis trackers. Smart control of the on-site eco-friendly power grid Cheetah Plains’ proprietor, Japie van Niekerk, said: “We have partnered with some of the world’s pre-eminent minds in the renewable energy field to provide clean energy solutions that drive both our hospitality and safari experiences here at Cheetah Plains.” In the interest of modernisation,the lodge has been equipped with a microgrid – its own on-site power grid –which is capable of reliably supplying electricity even to large three-phaseenergy consumers such as cooling systems or motors. This makes the entire system noticeably more efficient, meaning that the diesel generator only needs to be switched on when energy consumption is unusually high or in periods of bad weather.

For many kinds of technical equipment, good grid quality is indispensable; for others, it extends their lifespan. This quality is reflected in the stable line voltage and frequency, which the UPP guarantees. The system continuously monitors all the important grid parameters and facilitates automated operation. A total of six 60kW stringinverters is used in the installation.

Off-grid suppliers, DHYBRID and Blockpower, have implementedan environmentally friendly, independent renewable energy supply for theCheetah Plains Lodge, located in the world-famous Kruger National Park in SouthAfrica. Finance and Policy “The new energy systemdoesn’t just increase security of supply; it also ensures grid quality.Moreover, carbon emissions and noise pollution are both decreased,” DHYBRID’sCEO Benedikt Böhm reports. Generation The system comprises three solar plants with 895 photovoltaic (PV) modules in total and a one-megawatt hour lithium-ion battery storage system. BRICS The available peak power capacity for the lodge has been increased by four times to 250kW since it switched over to the microgrid from its previous energy supplier, state-owned power utility Eskom.
