The trainer must correspond to a system for the study of the electrical installations with off grid photovoltaic solar energy.

It must be composed of a photovoltaic inclinable module, 90 W, 12 V, complete with a cell for measuring the solar irradiation and with a temperature sensor and a supporting frame for the following modules:

  • battery protection module, 12 V, 32 A with the following components:

-32 A circuit breaker for control of the battery,

-LED indicator for the battery connection,

-4 mm security terminals black/red.

  • a rheostat module including knob for varying the resistance and terminals. Range: 0-80 Ω.
  • measuring instrument module to perform measurements of a photovoltaic system. It must include a series of instruments; input terminals +/- are placed on the left of each instrument and the output terminals must be on the right. It must provide DC, AC and environmental measurements. All instruments must show readings using the automatic decimal point position, starting from 1/1000 up to the maximum value of each measurement. Communication terminals must be located on the right low side of the panel; two RS485 connectors, one male and one female, must be available for the connection with the PC running the acquisition software and/or with other modules in a chain configuration. Instruments must support MODBUS RTU protocol over RS485 interface, used by the software application, available separately, to perform a guided analysis of the electrical characteristics on the modules of the trainer. The module must include 4 multifunction displays:

-No.2 for DC measurements and displaying data for Voltage, Power and Current: DC voltage ± 65V, DC current ± 30A, DC power autoscale,

-No. 1 display showing data for: Solar irradiance meter 0 ÷ 1000 W/m2, Thermometer 0 ÷ 400°C.

Connections of the Measuring Instrument Module:

-Connector for the calibrated cell and for the temperature sensor.

-Power supply connectors of the module: DC voltage must be between 10V and 35V.

-Power switch, for the module switching on/off.

-Connectors for DC signals measuring voltage, current and power.

-Connectors for AC signals measuring.

-RS 485 Communication port, for the SW application interface.

  • charge regulation module for charge regulation of the battery with the current supplied by the solar panel, it must include LCD screen to provide information on situations; the module must have protection against overload, temperature compensation, different charge modes of the battery (slow, fast, maintenance mode, etc), DC solar panel terminals, DC battery terminals & DC load terminals. Characteristics:

-Maximum charge current 30 A,

-Short-circuit current 30 A,

-Input voltage 12 V,

-Protection IP22.
