On-Grid Solar Energy With Storage

Model No. DL SOLAR-GTS

DESCRIPTION
Modular trainer for the theoretical and practical study of the electric energy generation from photovoltaic panels. With the on-grid solar energy with storage, it is possible to perform experiments to determine the characteristics of a photovoltaic panel, study its on-grid operation with the connection to the mains network and its operation with a grid-tie battery charge controller for storage.
The complete system is supplied with a sun simulation module for indoor use.

TECHNICAL SPECIFICATIONS
– Inclinable photovoltaic panel, approx. 90W, 12V, complete with a cell for measuring the solar irradiation and a temperature sensor.
– Sun simulator consists of halogen lamps to provide energy to the photovoltaic module for indoor use.
– Multifunction measurement module: solar irradiation (up to 1000 W/m2), solar panel temperature (up to 400°C), 2 DC power meters (65Vdc, 20Adc, 1000W) and 1 AC power meter (512Vac, 20Aac, 1000W).
– Load management module with three independent single-phase outputs for the dynamic study of different load types.
– Active DC load used in the renewable energies’ laboratories configurable as constant resistance or constant current.
– Singlephase transformer with full-wave rectifier and capacitive filter to power DC load from AC single phase supply.
– A Grid-tie inverter output at mains voltage, 12V, 300W
– Three-phase power analyzer. Measurement of voltages, currents, frequencies, active power, reactive power, and apparent power.
– Inverter charger module used in on-grid system to manage the energy stored in the battery, combining with solar & utility charging and AC output. It offers four charging modes including Solar priority, Utility priority, Solar and Utility & Solarandtwo output modes for Battery and Utility. It utilizes the MPPT technology. Its output is protected against over current and reverse polarity.
– Single-phase supply at the mains voltage and frequency. Key operated Output: Phase + N + T through 4mm safety terminals, protected with differential magneto-thermal switch.
– Industrial Human Machine Interface module with 7’’ TFT display. It is designed to be used and interfaced with the renewable energies’ laboratories instruments and drives, through its communication ports.
– Variable DC power supply that emulates a photovoltaic panel. The V/I characteristic of the output varies in function of the irradiation setting. Local or remote control via serial communication using Modbus RTU.
– Three-level frame.
