The PV combiner box is suitable for photovoltaic grid-connected and off-grid power generation systems. Its main function is to converge the input of PV array. It has three protection measures: The first: The PV combiner box is configured with photovoltaic dedicated high-voltage lightning arrester, DC fuse and circuit breaker to provide short circuit fault protection and lightning protection. The second: It has protect function of over-voltage and over-current so as to avoid damage to photovoltaic panels and inverters when the fault occurs. The third: The PV combiner box is also used to reduce the connection of the photovoltaic array to the inverter, optimize the system structure, improve the reliability and maintainability of the system, make the photovoltaic system at its best.
