Main features
• The structure is safe and reliable, with sufficient mechanical strength to ensure that the components will not shake or deform after installation and during operation:
• Protection level IP65, waterproof, dust-proof, rust-proof, and salt spray-proof, meeting the requirements of outdoor installation:
• Up to 24 photovoltaic arrays can be connected at the same time;
• The positive and negative poles of each battery string are equipped with photovoltaic-specific fuses for protection. The fuse base and fuse are used together to reduce the owner's later maintenance costs and effectively protect the personal safety of maintenance personnel;
• The DC output bus is equipped with a photovoltaic-specific lightning arrester. There is good surge protection function between the positive pole and the ground, the negative pole and the ground, and the positive and negative poles;
• The junction box is equipped with a modular intelligent detection unit to detect the current, output voltage, box temperature, lightning arrester status, and circuit breaker status of each string of components;
• The current measurement adopts Hall sensor perforation measurement, and the measuring equipment is completely isolated from the electrical equipment. Even if there is a problem with the measuring 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 detection unit sets the device address number and the operation should be simple and convenient, and the device address can be changed on the spot without auxiliary equipment;
• The power consumption of the modular junction box intelligent 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 built-in lightning protection function to effectively protect the device communication port;
• The modular combiner box intelligent detection unit adopts a DC 1000V/1500V self-powered mode, and the self-powered power supply adopts a modular glue-filled package. The power supply has functions such as anti-reverse connection, over-current, over-voltage protection, and anti-corrosion;
