Demonstration board MI 3088 simulates typical photovoltaic (PV) system with one PV module and DC/AC inverter. It repre-sents a typical installation that consist of PV string, DC switch box , DC/AC inverter and one phase connection to the power grid. It is intended for use preferably by sales personnel for demonstration of the measuring methods and procedures on DC and partially on AC side of a PV system.
Pravi Measuring functions
With this demo board all electrical tests according to EN 625446 can be
demonstrated: continuity, isolation, open circuit voltage Uoc, short circuit current Isc and polarity.
It simulates an I/V characteristic of a PV module/string.
Simulated output of the irradiance and temperature sensor.
Simulation of a DC/AC inverter with one DC input and single phase output.
