Product Description
CE Approved 6 Strings Combiner Box PV Array Combiner Box 6 Into 1 Solar Junction Box
PV combiner box in the on grid solar system
PV combiner box in the off grid solar system
PV combiner box in the solar pump system
1. In the solar power system, in order to decrease the connecting line, easy maintenance, reduce losses, optimize system structure, improving the safety and reliability of items, the PV combiner box is usually in need between the solar panels and inverter.
2. Except the PV junction function, the pc combiner box should also have reverse current prevention, over-current protection, over-voltage protection, lightning protection etc a series of perfect protection functions, meanwhile, checking the running state, current, voltage and power after junction, arrester state, collection of DC circuit breaker state and Arc detection, leakage detection(optional) and so on.
3. The PV combiner box we manufacture is equipped with all the functions mentioned above, configuration with on grid/off grid solar inverter to make up a complete set of solar power system.
4. When choose the pv combiner box, based on the input dc voltage range and output power of inverter, certain qty of panels will be connected in series as a string, certain strings in parallel will connect to the PV combiner box for junction, via control of circuit breaker and protection of arrester, then feed to the inverter.
Main Feature:
- Conform to CGC/GF002:2010: PV Array Junction Box Technical Specifications
- Connection Capacity: Allowable maximum 24 strings panels to connect, Nominal voltage of each string is 10A, maximum 15A
- Voltage & Current: Total output current is 250A, the maximum voltage is 1000Vdc
- Safety Protection: For each string, high voltage fuse protection and anti-connection protection
- Arrester Protection: Equipped with pv high voltage arrester protection
- Output Control: PV high voltage circuit breaker control the output, pressure-resistant DC1200V, fusing current is optional
- Outdoor Installation: In line with outdoor installation, protection class IP65
- Data Communication: Isolate RS485 port used for remote data communication, support MODBUS-RTU protocol
- Alarm Function: Built-in comprehensive protection alarm function, not only the various of alarm parameters are programmable set, but also each alarm function can be set "On" Or "Off"
- Arc Protection: Real-time the harmful arc in the DC circuit, once there is the harmful arc, alarm will work and directly make the trip switch and cut off fault circuit, accordingly, prevent the fire disaster etc from the arc.

Frequently Asked Questions
What is the function of a PV combiner box in a solar power system?
The PV combiner box simplifies connections between solar panels and the inverter, reducing line layout, minimizing power losses, and improving system safety, reliability, and maintenance convenience.
What protection capabilities does this combiner box provide?
It features reverse current prevention, over-current and over-voltage protection, lightning protection, high-voltage fuse protection for each string, and integrated high-voltage PV lightning arresters.
Can this PV combiner box be installed outdoors?
Yes, this PV combiner box is designed with an IP65 protection class rating, making it completely compliant with outdoor installation requirements.
Does this unit support remote monitoring and communication?
Yes, it features an isolated RS485 communication port that supports the MODBUS-RTU protocol for remote data transmission and status updates.
How does the integrated arc detection protect the system?
It monitors harmful arcs in the DC circuit in real-time. If a harmful arc is detected, the alarm activates and immediately triggers the switch to isolate the fault, preventing fire hazards.
