Photovoltaic Solar Energy Modular Trainer
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.

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.
