Detailed Explanation of Photovoltaic AC Combiner Box
In the solar photovoltaic power generation system, the combiner box will be used, also known as the solar combiner box, the solar photovoltaic combiner box, the photovoltaic array lightning protection combiner box, the solar power generation combiner box, the photovoltaic power generation combiner box, the photovoltaic lightning protection combiner box, the solar lightning arrester , Solar photovoltaic lightning protection device, photovoltaic lightning protection device.
For a huge photovoltaic power station, the amount of the combiner box only accounts for 1%, but 100% of the current passes through it, and the failure of the combiner box during commissioning, operation and maintenance accounts for 20-30% of the entire power station. In addition, unsafe combiner boxes are likely to cause fires, threatening property and life.
In the photovoltaic power generation system, the photovoltaic combiner box is a wiring device that ensures the orderly connection of photovoltaic modules and the confluence function. It means that the user can connect a certain number of photovoltaic cells with the same specifications in series to form a photovoltaic series, and then connect several photovoltaic cells in series. The photovoltaic series and parallel connection are connected to the photovoltaic combiner box. After the photovoltaic combiner box is combined, the controller, DC power distribution cabinet, photovoltaic inverter, and AC power distribution cabinet are used together to form a complete photovoltaic power generation system. electricity grid.
Most of the solar panel strings have to connect in parallel with several PV modules. PV combiner boxes is the safest solution to connect the solar cables of the PV array to your battery charge controller or the inverter. The combiner boxes contain cylindrical string fuses to protect the PV string from high current. The fuses are compulsory all solar arrays with parallel strings.
