In the solar photovoltaic power generation system, in order to reduce the connection between the solar photovoltaic cell array and the inverter, FEEO Technology is based on "SJT 11127-1997 Photovoltaic (PV) Power Generation System Overvoltage Protection-Guidelines" and "GB/T18479" -2001 Overview and Guidelines of Ground-mounted Photovoltaic (PV) Power Generation System" and the characteristics of photovoltaic systems, combined with our years of experience in combiner box design, we have developed combiner boxes with a number of patented technologies.Users can connect a certain number of photovoltaic cells with the same specifications in series to form photovoltaic series, and then connect several photovoltaic series in parallel to the combiner box. The photovoltaic inverter is used together to form a complete photovoltaic power generation system, which can be connected to the grid. Combiner box, according to the selection and design requirements of photovoltaic power generation grid-connected inverters, is divided into: 1-2 channels, 3-4 channels, 5-9 channels, 10-16 channels of photovoltaic series input confluence, and measured by the intelligent communication acquisition module and fault analysis, detection and localization.
