Solis 800V 1000A AC Combiner Box Essential Component for PV System

This industrial-grade AC Combiner Box from Solis is built to meet the rigorous demands of high-capacity solar installations, focusing on safety, reliability, and operational efficiency.

• Ultra-High Capacity Power Consolidation: With an impressive 1000A current rating and 800V voltage rating, this combiner box is capable of handling the aggregated output of numerous high-power string inverters. It is an essential component for centralizing power collection in massive solar farms and large industrial plants, streamlining the connection to the medium-voltage transformer.

• Comprehensive Electrical Protection: Equipped with high-performance Molded Case Circuit Breakers (MCCBs) for each input branch and a main output breaker. These provide reliable overcurrent and short-circuit protection, isolating faults to prevent system-wide downtime. A built-in Surge Protective Device (SPD) safeguards the entire system from transient overvoltages caused by lightning strikes or grid disturbances.

• Extreme Durability for Harsh Environments: The enclosure is constructed with heavy-duty, corrosion-resistant materials and boasts a high IP65 protection rating. This makes it completely dust-tight and protected against low-pressure water jets from any direction, ensuring long-term, trouble-free operation in extreme outdoor conditions, including coastal areas with high salinity.

• Enhanced Operational Safety and Control: The design prioritizes personnel safety with a clear and logical layout, secure isolation points, and comprehensive labeling. This allows for the safe disconnection of individual inverter strings or the entire array for maintenance, emergency response, or system expansion, all from a centralized location.

• Streamlined Installation and Maintenance: An optimized internal layout with pre-assembled busbars and standardized mounting points significantly reduces wiring complexity and installation time. This design also facilitates easier troubleshooting, routine inspections, and future system upgrades, lowering the overall balance of system (BoS) costs.

• Seamless System Integration: As a dedicated Solis component, it ensures full compatibility with the entire range of Solis three-phase inverters, providing a cohesive and optimized system architecture for large-scale projects and ensuring reliable data communication and power management.
