Product details
Product overview
ZLLX-PV Intelligent Photovoltaic Lightning Protection Junction Box combines DC inputs of up to 24 photovoltaic cell module strings into one or more outputs, each of which is equipped with fuse, and the output is equipped with lightning protector and circuit breaker, greatly simplifying the input wiring of DC power distribution cabinet and inverter. Provide lightning protection, short circuit protection and grounding protection. The junction box is divided into intelligent and non-intelligent types. The intelligent lightning protection junction box is internally provided with a junction monitoring unit, which can monitor the current input by each photovoltaic cell string, summarize the output voltage, the temperature in the box, the state of the lightning protector, the state of the circuit breaker, etc.
The internal arrangement of the device is simple and clear, and the wiring is neat and reasonable. High reliability and simple maintenance. Outdoor wall-mounted installation can adapt to various harsh environments. In addition to related core components, other components can be customized according to user requirements.
Functional characteristics
The protection grade of the junction box reaches IP65, which is waterproof, ash-proof, rust-proof and salt fog-proof, and meets the requirements of outdoor installation.
Up to 24 battery strings can be connected simultaneously;
The positive and negative poles of each battery string are equipped with photovoltaic special fuses to protect the aZLembly string in case of failure. The fuse base and fuses are used together to reduce the later maintenance cost of the owner and effectively protect the personal safety of maintenance personnel.
The adoption of photovoltaic special high-voltage lightning protector can protect the bus positive pole to ground and the bus negative pole to ground after bus convergence, and the continuous working power (Uc) can reach 1000VDC；.
The power supply module in the bus box can be connected with photovoltaic voltage up to 1000DCV;
The bus box measurement and control module adopts Honeywell Hall element (DC CT sensor) with reliable performance to collect and monitor current and bus voltage of each photovoltaic group string, alarm and locate local faults, and can measure the temperature in the bus box, detect the status of lightning arresters and output circuit breakers, etc.
The monitoring module in the bus box has a digital display function, which can display the current, bus voltage, temperature in the bus box, status of breaker lightning protector, system power, equipment addreZL and other relevant information on the equipment.
With RS485/MODBUS-RTU serial port communication;
Lightning protection is provided for the external interface parts;
Can receive the parameter download of the local monitoring device for analysis and proceZLing;
The working power supply of the bus box can be selected from the outside 220VAC/DC or the power supplied by the bus box itself. If the bus box itself is used to supply power, there is no need for separate wiring for power supply on site.
