and environmentally friendly [1]. It is considered less expensive when compared to the diesel generators that run on fossil fuels, which are highly polluted [2][3]. Especially in areas that do not have access to electrical energy sources, as well as in agricultural areas that need irrigation. Renewable energy is one of the most important renewable sources of energy. They are available and especially present inareas that are exposed to solar radiation throughout the year [4][5]. The surplus energy generated from solar cells can be used later. This energy can be stored by one of the basic storage methods available at the present time, such as batteries. This is one of the main and important storage methods which depends on it to store the excess energy. The stored energy is used in times of night and in cloudy weather [6]. In the solar energy system, the maximum energy can be obtained by studying the electrical properties. It depends on obtaining the maximum energy through the correct orientation of the solar cells. So that the solar radiation falling on the solar cells is vertically as possible to take advantage of it in obtaining the maximum energy. By studying the current and at maximum power by studying the different tilt angles. Egypt is among the countries

In this paper, DC modulators are designed that raise the constant voltage to the operating values and that feed the loads The electrical elements that make up the lifter are designed for DC voltage. The main components are designed, which consists of three main phases connected in series with each other. The first stage contains an electric coil that is designed with specific specifications according to the requirements of the load. It also contains a suitable IGBT electronic key selected according to the specifications of the load. The three phases that make up the device are completely identical. The operating strategy of the various electronic switches is compatible with the load operation strategy and specifications. Feeding the step-up device from a group of batteries designed according to the needs of the load. And connect the batteries in series according to the needs of the designer. And the output voltage of the device is controlled at a constant value. This device feeds the DC/AC voltage changer, which in turn feeds the previous load. Determine the level of constant voltage 320VDC to obtain an alternating voltage of 220VAC. The electronic switches are controlled at each stage according to the strategy designed for operation. This strategy was programmed and placed in the memory of the microcontroller, where the Arduino was chosen for this purpose. This type was chosen for its simplicity and ease of programming and operation. I.
