Merges DC power from multiple PV strings (up to 24 paths optional) into a single output, acting as a critical link between solar arrays and inverters. This "n-in, y-out" configuration streamlines power transmission.

Equips DC fuses/breakers for overcurrent protection, cutting off faulty circuits during short circuits. Integrated Type 1/2 surge protection devices (SPD) divert lightning strikes and grid surges.

Optional modules track string current, busbar voltage, breaker status, and internal temperature. Supports RS-485 or wireless communication for remote oversight.

Features DC switch disconnectors for quick system shutdown during maintenance or abnormalities.

Reduces cable length and line resistance, cutting power loss by 5–10%. Accommodates up to 1500V DC, compatible with high-power PV systems.

Simplifies wiring and installation by eliminating individual string-to-inverter connections. Fault troubleshooting focuses on box components, saving maintenance time.

IP65/IP66 protection rating resists dust and water, suitable for deserts and coastal areas. Operates stably in -25℃ to +65℃ and up to 5000m altitude.

Offers configurable input paths (6–24 strings) and optional anti-reverse protection. Supports parallel operation for large-scale systems.

Essential for multi-string systems (over 3 strings), integrating inverter outputs for grid connection. Optimizes yield for open-field solar farms.

Simplifies wiring for rooftop arrays, matching factory and warehouse energy demands.

Ideal for desert solar parks and coastal PV projects due to weather-resistant design.

Wireless communication options suit existing system upgrades without rewiring.
