EN 01.6 – Computerized Photovoltaic Installation Demonstrator

The EN 01.6 equipment scales a complete photovoltaic solar system. It has been designed with special emphasis on the didactic aspect of the same, being able to observe at a glance all the components that a solar photovoltaic installation has and its arrangement. It allows the study, of both isolated photovoltaic solar energy installations and grid connection.

Description

The equipment consists of: 2 photovoltaic panels of 20Wp, 2 batteries, regulator, insulated inverter, grid inverter, solar panel emulator, pyranometer, temperature sensors in panels, various DC and AC loads, and module control and data acquisition.

It has cables ready to connect and disconnect the various elements of the installation in different ways, being able to observe and analyze the operation of the panels connected independently, in series, in parallel, with batteries in series or in parallel, with direct output in Direct current or direct current to AC converter, working in isle or connected to the grid.

It is provided with elements of measurement of the variables necessary to analyze the characteristics of the panels and their behavior. Thus, it has a pyranometer that indicates the intensity of radiation that affects the panels, with voltmeters and ammeters that show us respectively the voltage and the intensity generated.

It also has ammeter and voltmeter in each of the batteries to indicate the state of these and the direction of flow of the current in them, that is to say if they are loading or providing load, and also has a measuring instrument that provides us all the characteristics of the alternating current obtained after the inverter.
