Product Description
Intelligent Photovoltaic Combiner Box Power Distribution Cabinet for Solar System String Box
Product Description
The LX-PV intelligent photovoltaic lightning protection combiner box combines up to 24 DC input combiners of photovoltaic cell modules into 1 or multiple outputs, each with a fuse, and the outputs are equipped with lightning arresters and circuit breakers, greatly simplifying the input wiring of DC distribution cabinets and inverters. Provide lightning protection, short circuit protection, and grounding protection. The junction box is divided into two types: intelligent and non intelligent. The intelligent lightning protection junction box is equipped with a current monitoring unit inside, which can monitor the input current of each photovoltaic cell string, summarize the output voltage, the temperature inside the box, the status of the lightning arrester, and the status of the circuit breaker.
The internal layout of the device is simple and clear, and the wiring is neat and reasonable. High reliability and simple maintenance. Outdoor wall mounted installation, capable of adapting to various harsh environments. In addition to related core components, others can be customized according to user requirements.
Functional characteristics
The protection level of the junction box reaches IP65, which is waterproof, dustproof, rust proof, and salt spray resistant, meeting the requirements for outdoor installation; Can simultaneously connect up to 24 battery strings;
Each positive and negative pole of the battery string is equipped with photovoltaic dedicated fuses to protect the module string from faults. The fuse base and fuse are used together to reduce maintenance costs for the owner and effectively protect the personal safety of maintenance personnel;
The use of photovoltaic dedicated high-voltage lightning arrester can protect the positive pole to ground and negative pole to ground of the busbar after convergence, and the continuous working electricity (Uc) can reach 1000VDC; The power module inside the combiner box can be connected to a photovoltaic voltage of up to 1000DCV;
The measurement and control module of the combiner box adopts reliable Honeywell Hall elements (DC CT sensors) to collect, monitor, alarm, and locate local faults for the current and bus voltage of each photovoltaic string. It can also measure the temperature inside the combiner box, detect the status of lightning arresters and output circuit breakers, etc;
The monitoring module inside the combiner box has a digital display function, which can display the current of each component string, bus voltage, temperature inside the combiner box, status of circuit breaker lightning arrester, system power, and equipment address on the equipment;
Equipped with RS485/MODBuS RTU serial communication;
The external interface is equipped with lightning protection;
Can receive parameter downloads from local monitoring devices for analysis and processing;
The working power supply of the combiner box can be selected from external 220VAC/DC or from the power supply provided by the combiner box itself. If the power supply is provided by the combiner box itself, there is no need for specific power supply and separate wiring on site.Product Parameters
