PRODUCTS DETAILS

      overview Photovoltaic combiner boxes are used in photovoltaic power generation systems to reduce the connection lines between photovoltaic modules and inverters. Through the protection of photovoltaic special fuses, circuit breakers and lightning arresters, the reliability is improved and the maintenance of the system is also convenient.According to the DC voltage range input by the inverter,the user can connect a certain number of photovoltaic modules with the same specifications in series to form a series of photovoltaic modules and then connect several series to the lightning protection combiner box of the photovoltaic array. Output after circuit breaker protection,which facilitates the access of the rear inverter. MLPV-DC main feature The cabinet is made of hot-dip galvanized steel.The cabinet structure is safe andreliable,and has sufficient mechanical streneth to ensure that the components are not shaken or deformed after installation and operation; Protection level IP65,with waterproof,anti-dustanti-rustanti-salt spray, to meet the requirements of outdoor installation; Up to 24 photovoitaic arrays can be connected at the same time; The positive and negative poles of each battery series are equipped with photovoltaic special fuses for protection, and the fuse base and fuses are used together to reduce the maintenance cost of the owner and effectivelyprotect the personal safety of maintenance personnel; The DC output busbar is equipped with a photovoltaic special lightning protector.Positive pole to ground,negative to ground, and positive and negative poles have good surge protection function´╝Ť The combiner box is equipped with a modular intelligent detection unit to detect the current,output voltage,box temperature, lightning protection device status, and circuit breaker status of each string of components; The current measurement adopts Hall sensor perforation measurement,and the measurement equipment is completely isolated from the electrical equipment. Even if there is a problem with the measurement unit,it will not affect the normal power generation of the system,effectively improving the power generation efficiency and equipment safety; The intelligent detection unit has a digital display function,which can display current,voltage, power,temperature, device address, device number and other information on the device body;the operation of setting the device address number of the detection unit should be simple and convenient,and the device address can be changed on the spot without auxiliary equipment; The power consumption of the modular combiner boxintelligent detection unit is less than 4W,and the measurement accuracy is 0.5%; it has multiple ways of data remote transmission,provides RS485 interface and wireless ZigBee interface, and the communication interface has a built-in lightning protection function,which can effectively protect the communication port of the device; The intelligent detection unit of the modular combiner box adoptsa DC 1000V/1500V self-powered mode,and the self-powered power supply is packased with modular elue.The power supply has anti-reverse connection.over-current.over-voltase protection. anti-corrosion and other functions; MLPV-DC
