Solar PV Combiner AC DC Solar Junction Box 6 Strings in 1
Product Description
Junction box/Combiner box in the on grid solar system
Junction box/Combiner box in the off grid solar 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 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 with CGC/GF002:2010, PV Array Junction Box Technical Specifications
- Allowable maximum 24 strings panels to connect, Nominal voltage of each string is 10A, maximum 15A
- Total output current is 250A, the maximum voltage is 1000Vdc
- For each string, high voltage fuse protection and anti-connection protection.
- Equipped with pv high voltage arrester protection
- PV high voltage circuit breaker control the output, pressure-resistant DC1200V, fusing current is optional
- In line with outdoor installation, protection class IP65
- Isolate RS485 port used for remote data communication, support MODBUS-RTU protocol.
- 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”
- 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 main function of the PV combiner box?
In solar power systems, the PV combiner box is used between solar panels and the inverter to decrease connecting lines, simplify maintenance, reduce energy losses, optimize system structure, and improve safety and reliability.
What protection functions does this junction box support?
It features comprehensive protection including reverse current prevention, over-current protection, over-voltage protection, lightning protection, DC circuit breaker control, harmful arc detection, and optional leakage detection.
Can this combiner box be used for both on-grid and off-grid solar systems?
Yes, this PV combiner box is designed to configure with both on-grid and off-grid solar inverters to establish a complete solar power system.
What is the environmental protection class of this product?
The combiner box is designed for outdoor installation with a protection rating of IP65, operating normally between -40°C to 70°C under 95% humidity.
Does this device support remote data monitoring?
Yes, it includes an isolated RS485 port for remote data communication, supporting the MODBUS-RTU protocol to monitor status, current, voltage, and alarms.
What happens if a harmful arc is detected in the DC circuit?
Once a harmful arc is detected, the built-in system activates an alarm and directly triggers the trip switch to cut off the faulty circuit, preventing potential fire hazards.
