  • 1
    In the solar power system, in order to decrease the connecting line, simplify maintenance, reduce losses, optimize system structure, and improve safety and reliability, the PV combiner box is typically required between the solar panels and the inverter.
  • 2
    Beyond basic junction capabilities, the PV combiner box provides reverse current prevention, over-current protection, over-voltage protection, lightning protection, and other essential safeguard functions. It also monitors operations, including voltage, current, power collection after junction, arrester status, DC circuit breaker status, arc detection, and optional leakage detection.
  • 3
    Our manufactured PV combiner box features all the functions mentioned above and configures seamlessly with both on-grid and off-grid solar inverters to establish a complete solar power system.
  • 4
    When selecting a PV combiner box based on the input DC voltage range and output power of the inverter, a specified quantity of panels connects in series as a string. Several of these strings then connect in parallel to the PV combiner box for junction control, routed through circuit breakers and surge protection before feeding into the inverter.

Frequently Asked Questions (FAQ)

What is the primary function of a PV combiner box?
A PV combiner box connects multiple solar strings in parallel to simplify wiring between the solar panels and the inverter. It minimizes power losses, optimizes system structure, and enhances overall safety and maintenance convenience.
What safety protection features are included in this box?
This combiner box comes equipped with high-voltage fuse protection, reverse current prevention, over-current/over-voltage protections, lightning surge protection, and a pressure-resistant DC1200V output circuit breaker.
Is this solar junction box suitable for outdoor installation?
Yes. The combiner box is designed specifically for outdoor environments and meets the IP65 protection standard, ensuring strong dust and water resistance.
How does the integrated DC arc detection feature prevent hazards?
The built-in arc detection system monitors the DC circuit in real-time. If a harmful electrical arc is identified, the system instantly triggers an alarm and trips the circuit switch to isolate the fault, preventing potential electrical fires.
Can this combiner box communicate data remotely?
Yes, it features an isolated RS485 communication port that supports the standard MODBUS-RTU protocol, enabling remote monitoring of real-time voltage, current, and alarm statuses.
