GEYA GYPV/2-1 DC Solar Combiner Box – Junction Box for 2 Strings

Product detailed description

The solar connection box (DC Combiner Box) GEYA GYPV/2-1 is a professional, pre-wired solution for connecting photovoltaic panels to an inverter. The model is used to combine two separate strings into one output, significantly simplifying cabling and saving time during the installation of a photovoltaic power plant.

The box provides comprehensive electrical protection for your solar power plant. Inside the box, DC circuit breakers are pre-installed for each input, overvoltage protection SPD T2, which protects the inverter from lightning and inductive overvoltage, and a main DC circuit breaker for safe disconnection of the system during maintenance.

The box is made of durable plastic with UV protection and an IP65 rating, ensuring protection against dust and water. For simple and reliable connection of solar cables, the box is equipped with waterproof MC4 connectors at the input and output.

Main advantages and applications

• Completely pre-wired: ready for immediate installation (Plug & Play), saves time and minimizes errors during wiring.
• Comprehensive FVE protection: protection against overload, short circuit and overvoltage caused by lightning strikes.
• 2 inputs / 1 output: combines two branches of photovoltaic panels into one output line to the inverter.
• IP65 and UV resistance: suitable for installation in the exterior (on the façade, under panels) and interior (technical rooms, garages).
• MC4 connectors included: simple and tight connection of solar cables without complicated screwing of seals.
• Wide compatibility: suitable for single-phase and three-phase inverters with one MPPT tracker (monocrystalline, polycrystalline and thin-film panels).
