EN 01.4PC – Computerized Stand Alone Photovoltaic Installation Demonstrator

The equipment EN 01.4 has been designed as a stand alone photovoltaic solar power plant, with 2 modules and all the elements necessary to complete the installation.
Description
The equipment consists of: 2 photovoltaic panels of 20Wp, 2 batteries, a voltage regulator, an inverter, a pyranometer, different loads in DC and AC, and modules of control with PC (PC included).

This working station is equipped with tension and current meters in the key sections, to make it easy for the student to understand its operation.

The system works in exactly the same way as the photovoltaic stand alone facilities of electrical generation, that are normally used on boats, caravans, pumping groups, or remote locations where access to the public mains does not exist.

In addition, this equipment allows for the connection of the panels and the batteries, in series or in parallel.
