Photovoltaic Installation Demonstrator - stand alone and network connected (EN 01.5)
PL-203284
STAND ALONE AND NETWORK CONNECTED
The equipment EN 01.5 reproduces a scale, complete photovoltaic solar installation. It has been designed with special emphasis on the didactic aspect. It offers the opportunity to observe all the components of a real photovoltaic solar installation and its layout.
DESCRIPTION
It is supplied with adapted cables to connect and disconnect the components of the installation in different ways, so allowing to observe and analyze the operation of the connected panels in series, parallel, with batteries in series or in parallel, with direct exit in DC or AC, working standalone or connected to the network.
The equipment is supplied with metering devices for the variables necessary to analyze the characteristics of the panels and their behavior. Likewise, it has a pyranometer that indicates the intensity of solar radiation that affects the panels, with tension and current meters to show to the generated voltage and its intensity.
Additionally, it has tension and current meters in each one of the batteries to indicate the state of these and the direction of the current, if they are being loaded or contributing load, and it also has a metering device that shows a complete description of the obtained alternating current after the standalone inverter.
The grid connected inverter is implemented with software where the parameters of generation can be observed. In order to feed the grid-connected inverter, there are 3 panel simulators, with power regulation and tension and current metering devices.
