Solar PV

Photovoltaic Solar Energy Modular Trainer, "MINI-EESF", is a laboratory scaled unit designed to study all the parameters involved in the solar radiation direct conversion into electricity. The trainer is based on some application modules and photovoltaic solar panels assembled in mobile structures.

It is specially designed for the theoretical and practical study of the electrical installations with photovoltaic solar energy, the typical configurations used in photovoltaic installations and the operation of the different elements involved in the conversion.

The power obtained from the solar energy can be:


  • Regulated to obtain a DC power to charge a battery, studying parameters such as solar module´s current output charge level, battery voltage, etc.
  • Delivered to DC loads, studying parameters such as solar module´s current output and current consumption by the loads.
  • Converted to AC power to be delivered to AC loads, studying parameters such as current consumption by the loads.
  • Injected to the grid, studying pPhotovoltaic Solar Energy Modular Trainer, "MINI-EESF", is a laboratory scaled unit designed to study all the parameters involved in the solar radiation direct conversion into electricity.

 Dimensions: 660 x 35.5 x 780 mm. Weight: 3 Kg. approx.
Lamps Module:
    Composed by two lamps to simulate the sunlight. Regulated Power from 0 to 400 W.
Battery offering optimal performance with low power applications.
Set of interconnection cables.
Rack for modules allocation:
N-ES10. Solar charge controller with an automatic recognition for operating voltage 12 V or 24 V. It monitors several parameters such as voltage, current and charge level of the battery, load current, status, etc. Additional functions can be activated such as the settings, night light function and auto-test. The regulator is equipped with various devices to protect its electronics, battery and load.
N-ES20. Loads module that incorporates two 12 V, 20W lamps, with independent switches.
N-ES30. DC/AC inverter that outputs a sinewave shaped output of 230V/50Hz ± 2% and the nominal input voltage is 12Vdc. Two different operating modes: continuous mode and ASB mode (Auto Standby) to reduce the power consumption. It is provided with a diagnosis system to indicate the user the status by different flash sequences.
N-ES40. AC Voltage measurements module until 250V. and DC until 250 V. (digital multimeter).
N-ES50. Loads module that incorporates two lamps of 220V., 50 W., with independent switches.
N-ES80. Module for measurements of solar irradiation (W/m2) and measurements of current until 10 A., with digital multimeter.
N-ES90. Module for 12Vdc battery charger.
EE-KIT2. Grid Connection Inverter Kit.
 Inverter used for the conversion and injection to the grid of the power generated by a simulated source of renewable energy. The simulated source is a simulator used to obtain a variable power to be injected to the grid.
 The operation mode is displayed by means of an indicating LED at the front side of the housing.
 It is equipped with extensive safety measures to ensure that it is immediately switched off as soon as the AC plug is removed from the wall socket or the operation of the public grid fails.
 The inverter can be connected to a computer (PC) through a RS232/USB communication to display some parameters, such as voltage and current inputs, mains voltage and frequency, maximum AC power, Kwh, etc.
 - Grid Connection Inverter:
 Input (DC):
  Nominal power @ 25ºC: 150 W. Maximum power @ 25ºC: 220 W. MPP voltage: 45-125V DC. Maximum voltage: 155V DC.

 Output (AC):
 Voltage: 230V (207 - 253 V). Maximum power, fuse: 2A. Frequency: 50 Hz (49.8 ~ 50.2 Hz).
 This unit is supplied with the Grid Simulator (ESR), which simulates a low power grid to inject the power generated by the inverter.
 - Grid Simulator (ESR):
ESR is designed to create an isolated low power grid. The unit uses a battery as voltage source and generates a sine signal of 220V/50Hz. The main features of the ESR are:
 Inlet voltage source: battery of 12Vdc.
  Output: 220V/50Hz.
  Isolation transformer.
  Battery charger included.
  Protection fuses.
