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.
