Due to its geographical position in the solar belt, Algeria benefits from an abundance of solar energy. The average annual amount of sun hours is 2780 hours, 116 days [1].
The energy generated by the solar panel is in the DC form and needs to be transformed to supply AC loads or to inject it into the AC distribution network.
In this work, an off-grid inverter has been developed to obtain a signal that can be used for daily applications.
The off-grid inverter can be the solution for all kinds of scenarios, such as residential appliances and commercial applications. It is portable and suitable for many other applications, on personal vehicles and in remote villages where electricity is unstable. Its independence from the grid gives it the ability to be used as a backup power supply using only batteries.
In our project, we present the design and development process of an off-grid inverter. The main parts consist of a 100-Watt solar panel. controller capable of extracting the maximum power from the solar panel and regulating the voltage and current to maintain a safe charge level for the battery, and a solar inverter with a power of 100VA, an input voltage of 12VDC, a sinusoidal output with a voltage of 220VAC, and a frequency of 50Hz.
The ESP32 was used to control all the circuits in real-time (FREE-RTOS). It was used to generate PWM control signals, collect sensor data, and many other tasks.
Our work is divided into four chapters and a general conclusion:
In the first chapter, we present the state of the art of inverters.
In the second chapter, we present a general overview of photovoltaic panels and the different converters of our OGI.
The third chapter is devoted to the design and experimental realization of our inverter, and we present the different composites we used.
The last chapter is devoted to the experimental result.. | | En ligne : | D:\CD THESES 2021\MAST ELN\BOUZIANE AMIR; CHIKH KARIM.PDF | | Format de la ressource électronique : | PDF | | Permalink : | ./index.php?lvl=notice_display&id=36364 |
