The Christiani PV-Trainer
A modern PV system with battery storage, grid connection and energy management - combined in a compact teaching system
Together with the PV generator, the Christiani PV trainer fully replicates a modern photovoltaic system. Self-consumption, grid connection and emergency power supply, with optimised control of the energy flows, with clear and transparent monitoring at all times: these are the key features of the PV-Trainer. State-of-the-art safety technology guarantees safe and secure learning and working.
Communicating forward-looking technology in an interesting, modern and practice-orientated way.
A complete and mobile photovoltaic installation in the classroom or specialist room. The teaching system can be used to map almost all practical tasks, plans and configurations that are encountered or requested by customers and can be integrated flexibly and efficiently into everyday training programmes.
The components of the PV-Trainer allow both the installation of a photovoltaic system with full feedin and the configuration of a typical self-consumption system. To optimise the self-consumption rate, a home storage unit is also installed, which can be flexibly integrated into the configuration of the system depending on the respective learning situation.
On delivery, the system is configured country-specifically and connected to an Internet portal for data visualisation. Alternatively, the system can be connected to the Internet via the router installed in the communication unit using a LAN connection or its own SIM card. The tablet on the system can be used to call up both the local values of the inverter and the data and values stored in the portal.
The system can also be expanded with various additional components, such as a PV tester for standardised measurement of the PV generator or switchable radio-controlled sockets for intelligent load control.
The system fulfils all required standards, including those for power generation systems on the lowvoltage grid (VDE-AR-N 4105) and the requirements for testing and documentation of photovoltaic systems (DIN VDE 0126-23-1)
