IP65 IP66 Weatherproof Solar Combiner Box With 1500V DC Compatibility Class II Double Insulation

Optimize and safeguard your solar energy infrastructure with our High Safety Insulated Solar Combiner Box. Specifically engineered for commercial, industrial, and residential outdoor photovoltaic (PV) projects, this premium combiner box synthesizes multiple DC inputs from solar strings into a single, unified output.

Built from high-performance, weather-resistant insulation materials, it delivers maximum protection against extreme environmental hazards while integrating critical safety mechanisms, including overcurrent protection, surge suppression, and rapid DC isolation. Whether you are installing a utility-scale solar farm or a robust rooftop array, this combiner box ensures long-term operational continuity, system efficiency, and structural safety.

• Commercial & Industrial (C&I) Rooftop Arrays: Seamlessly groups numerous high-power solar strings into central lines before running cables down to commercial string inverters.
• Residential Solar Installations: Provides a compact, neat, and fire-safe exterior sub-panel for household solar and energy storage integration.
• Ground-Mounted Utility Solar Projects: Built tough to handle large-scale utility fields exposed to shifting wind loads, blowing sand, and extreme temperature fluctuations from -25°C to +60°C.
• Off-Grid Solar Storage Systems: Acts as the perfect protection hub for remote telecommunication power stations, agricultural water pumps, and off-grid microgrids.

• Pre-Wired Internal Layout: Units are delivered fully assembled, pre-wired, and tested internally, significantly saving installation hours and reducing field wiring mistakes.
• Customization Available (OEM/ODM): We offer flexible configurations tailored to your system architecture, including custom input string counts, specialized monitoring modules, and personalized brand labeling.
• Strict Quality Control: Every combiner box undergoes a rigorous 100% factory inspection, including insulation resistance testing and high-voltage simulation tests before shipment.

A: Yes, we offer distinct models rated for either standard 1000V DC configurations or advanced high-efficiency 1500V DC commercial systems. Please specify your system voltage requirements during procurement.

A: Standard configurations utilize precision DC fuses for string protection. If your specific PV module configuration or shading profile requires anti-reverse diodes, they can be integrated seamlessly into a custom order.

A: Absolutely. The box comes equipped with pre-molded, highly reliable PG waterproof cable glands or knockouts that ensure a clean, airtight lock with standard solar cables and electrical conduits.
