The trainers are composed of: • Two solar photovoltaic panels (85W, 12V) mounted on a support with wheels and complete with graduated scale on one side for adjustment of the inclination and calibrated cell in the upper part for measuring the solar irradiance and temperature. • Motor/generator group for the simulation of a wind turbine. Composed of a brushless motor coupled to 24V AC 3ph generator, motor controller module, anemometer for real wind detection • Wind turbine electronic regulator for battery charging • Two 2400 W DC/AC converter module (2400 W each), with sinusoidal output to generate an electrical network (mains). With a circuit breaker to switch on and off the inverter. It operates as master or slave. Complete with control panel. Integrated MPPT solar charge controller, two 12V batteries. It permits Public Grid connection to charge the battery or act as a backup if local energy is not available. • 24Vdc load module with two 20W halogen lamps, with an On/Off control switch. • 24Vdc load module with two 3W LED lamps, with an On/Off control switch. • Mains voltage load module with a 35W halogen lamp and a 3W LED lamp. Each lamp incorporates an On/Off control independent switch. • Variable logarithmic rheostat module, 80Ω, 6A max., to load the photovoltaic panel in order to detect the voltage-current characteristic curves. • Instruments module for measuring solar parameters. It displays: voltage-current-power, solar irradiance, temperature of the solar panel. • Instruments module for measuring wind parameters. It displays: voltage-current-power, wind speed, shaft speed, wind direction. • Two sun simulator for solar photovoltaic panel internal use. The intensity of the light can be controlled by the operator locally through a potentiometer and remotely through a DC 0-10 V signal or ModBus command. • Frame for the modules.
