Hybrid renewable energy systems are becoming popular as stand-alone power systems (off-grid, not connected to any electricity distribution system) for providing electricity in remote areas due to advances in renewable energy technologies. A hybrid energy system usually consists of two or more renewable energy sources used together to provide increased system efficiency as well as greater balance in energy supply. For the times when neither the wind nor the solar system are producing, most hybrid systems provide power through batteries and/or an engine generator powered by conventional fuels, such as diesel. De Lorenzo provides for this category two systems and each with variations to give the final user the possibility to choose the one he likes most. Off-grid and On-grid hybrid systems with DC motor kit or stepper motor kit for indoor use of the wind turbine with option a light simulator to irradiate the solar panels in case of indoor places. For those systems, it is also possible to replace the standard solar panel with a solar tracking panel and monitor its meaningful parameters comparing them with the expected optimal setting according to the actual sun position. Another big system with two versions (24V or 12V) and where, for the two inverters, one acts as master and one as slave to create a connection between the two outputs that operate as a single line with double available power. All these trainers are supplied with software for data acquisition and processing. They are recommended for high schools and first years of university.
