CARLO GAVAZZIAutomation ComponentsManagement and control system for photovoltaic plants
Eos Eos Array, Eos Box, Eos Gate Protecting the environment is a fundamental ideal that requires dedication and care, which is why every solar project is a vital project. It needs the same attention that we devote to the things we love. Care and attention, are essential values for Carlo Gavazzi, when developing the control system for photovoltaic plants. This ensures the solar investment is a solid investment. The Carlo Gavazzi solution develops with Eos-Array, Eos- Gate and Eos-Box depending upon the requirements and complexity of the photovoltaic plant. Eos-Array and Eos-Array Lite are systems comprised of individual modular elements that, when interacting with one another, provide efficient local control to the solar plant. Whether it’s a small/medium power or high power plant, you are assured there is effective information management. The Eos-Array provides a compact, simple, versatile and innovative solution. Eos-Box is a web server that controls and supervises the whole installation, while Eos-Gate using WEB-Service technique sends data to WEB portals. Both solution can gather data from: • Eos-Array groups; • Inverters; • Energy meters. The Eos-Box and the Eos-Gate provide information in a quick and automatic fashion via the internet, so the data is available wherever you are.
