Product Overview: PV Combiner Box

Our PV Combiner Boxes are designed to combine the output of multiple solar PV strings into a single DC output, providing essential protection, monitoring, and disconnection functions. Built with durability and long-term outdoor performance in mind, they are ideal for commercial, industrial, and utility-scale solar installations.

Key Features & Advantages:

• Robust & Durable Construction:

  • High-Quality Materials: Fabricated from premium galvanized steel, aluminum alloy, or stainless steel (upon request) for superior corrosion resistance and mechanical strength.

  • Weatherproof & IP Rated: Designed to withstand harsh environmental conditions (UV exposure, rain, dust, and extreme temperatures). Standard IP65 rating ensures complete protection against dust and water jets.

  • Precision Fabrication: Utilizing our in-house laser cutting, CNC punching, and CNC bending equipment, we guarantee perfect dimensional accuracy, smooth edges, and a seamless fit for all components.

• Enhanced Safety & Protection:

  • Integrated DC Protection: Configurable with DC fuse holders, surge protection devices (SPD), and isolator switches to safeguard against overcurrent, lightning strikes, and overloads.

  • Safe & Organized Wiring: Spacious interior layout with dedicated cable glands, DIN rails, and terminal blocks for neat, secure, and easy wiring, reducing installation time and risk.

  • Reliable Grounding: Ensures proper system grounding for enhanced safety.

• Functional Design & Customization:

  • Modular & Scalable: Flexible design to accommodate various numbers of input strings (e.g., 4-in-1, 8-in-1, 16-in-1, 24-in-1) and component configurations.

  • Monitoring Ready: Optional integration points for current monitoring sensors (with meter) and voltage monitoring to facilitate system performance tracking.
