High-Quality PV Combiner Box/Reliable Solar Energy Distribution Solution

A combiner box is a critical component in photovoltaic (PV) systems that consolidates multiple solar panel strings into a single output line. It integrates protection devices such as fuses, surge protectors, and circuit breakers to ensure system safety, reliability, and ease of maintenance.

GEYA’s combiner boxes are engineered to meet international standards, including CGC/GF 037:2014, and are widely used in residential, commercial, and industrial solar installations.

  • High Reliability: Equipped with DC fuses and DC surge protection devices (SPD) to safeguard against overcurrent and lightning strikes.
  • Strong Adaptability: IP65-rated enclosure ensures waterproof, dustproof, and UV-resistant performance. Suitable for harsh outdoor environments.
  • Flexible Configuration: Compatible with monocrystalline, polycrystalline, and thin-film solar modules. Supports custom current ratings for fuses and breakers.
  • Easy Installation: Simplified wiring design with MC4 waterproof connectors and wall-mounted design.
  • Robust Construction: Made from cold-rolled steel or PVC engineering materials, tested for fire resistance, impact, and temperature endurance.
