Off grid BESS and photovoltaic/wind turbine application

In this application, the energy source is a photovoltaic system combined with storage batteries in island mode. The system uses solar energy to generate electricity, which is stored in the batteries for later use.
In island mode, the system operates independently of the main electrical grid. Solar energy captured during the day is stored in the batteries, providing continuous power even when the sun is not shining, such as at night or on cloudy days.
This configuration can offer a significant level of energy autonomy, particularly suited to isolated sites or installations where power reliability is important. However, it is important to note that autonomy is dependent on the duration and intensity of sunlight. In the event of prolonged periods without sunlight, battery capacity may be reduced, limiting the power supply. Nevertheless, this solution offers clean, renewable energy, maximizing the use of solar power and reducing dependence on traditional energy sources, while contributing to a reduction in carbon emissions.
