PROSURGE PSCB-...P11 Series PV Combiner Boxes – Durable, Safe, and High-Performance DC Protection for Solar Systems Up to 1500V DC, Supports 1×1 String Connection
The PROSURGE PSCB-...P11 Series Photovoltaic (PV) DC combiner boxes are engineered for reliable overvoltage and short circuit protection in solar power systems. Featuring a high-strength, UV-resistant plastic enclosure with an IP65 weatherproof rating, these combiner boxes are built to withstand harsh outdoor environments, making them ideal for both residential rooftop and large-scale industrial PV installations.
Designed for system voltages of 1000V and 1500V, the PSCB-...P11 Series integrates essential protection components including DC circuit breakers, isolator switches, DC surge protective devices (SPDs), DC fuses, PV connectors, and waterproof cable glands. The series provides comprehensive safeguards against lightning surges, short circuits, and ground faults, ensuring long-term system reliability and inverter safety.
Fully compliant with IEC 61643-32, these PV combiner boxes offer multiple configuration options, including single or multi-string outputs, flexible customization of non-core components, and easy wall-mounting installation. By combining multiple PV strings into a single output, they reduce cable usage, simplify wiring, and lower overall installation costs.
Whether you are protecting residential solar arrays or utility-scale photovoltaic plants, the PROSURGE PSCB-...P11 Series delivers the durability, safety, and performance you need to maximize system uptime and equipment lifespan.
