Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Three-Phase Solar Power Distribution: Designed to manage and distribute three-phase electrical power in photovoltaic (PV) systems, ensuring efficient grid connectivity and energy flow regulation.
  • Voltage Control & Protection: Equipped with transformers for voltage adjustment and circuit breakers/relays to safeguard against overloads and electrical hazards, optimizing system reliability.

Key features

  • 1. Durable Corrosion-Resistant Steel Construction

    • With a robust steel and stainless steel body, this cabinet ensures long-term reliability in harsh outdoor environments. The corrosion-resistant material outperforms standard metal enclosures, safeguarding internal components against rust and wear.

  • 2. Modular Design for Easy Customization

    • With a modular internal layout and color-coded wiring, you can quickly adapt the cabinet to diverse solar system configurations. This design reduces installation time by up to 25% compared to fixed-configuration cabinets.

  • 3. High-Capacity Three-Phase Power Handling

    • Equipped with transformers and circuit breakers, this cabinet supports commercial-scale solar systems with high voltage and current demands. It handles 400V three-phase grids, outperforming single-phase models in industrial applications.

  • 4. Industrial-Grade Safety and Reliability

    • Certified to CE and ETL standards, the cabinet ensures compliance with global safety protocols. Its integrated circuit protection and grounding systems provide superior fault tolerance compared to non-certified alternatives.

  • 5. Continuous Operation for Commercial Solar Systems

    • Designed for 24/7 grid-connected use, the cabinet’s reinforced carbon steel frame and thermal management features maintain stable performance in industrial settings, unlike residential-grade enclosures prone to overheating.
