EDS® Energy Lab – Outdoor system for renewable energy

EDS® Energy Lab – Outdoor system for renewable energy

The concept

Technicians and engineers with qualifications in the area of renewable energies and energy management are urgently needed, in both industry and the public sphere. Consequently, these topics are now firmly established in the curricula of many educational institutions.

Festo Didactic has an optimized solution for educational purposes: the EDS® Energy Lab.

Photovoltaic modules and wind power turbines generate real "green" electricity and transmit it to a robust, climate-controlled container. A battery system uses this to create a stand-alone electricity grid, which can supply internal and external power consumers.

Sensors are used to measure environmental conditions such as solar radiation, wind speed, and temperatures, as well as performance data, the generator, batteries, and power consumers.

All functions can be controlled, observed, and demonstrated in the container.

The configurable data collection system makes the measurement and operational data available via a webserver. Prepared views and interactive information pages offer a quick introduction to the different topics.

High-performance data input makes possible detailed data analysis – with and without SQL knowledge. End devices connected to the network with web browser are sufficient for access.
