Solis 800V 630A inverter AC Combiner Box Essential Component for PV System

This high-capacity AC Combiner Box from Solis is engineered to provide a safe, organized, and efficient interface between multiple inverters and the main grid feed in large photovoltaic systems.

• High-Capacity Power Consolidation: Designed to handle high voltages up to 800V and currents up to 630A, this box is capable of combining the AC output from a large array of three-phase inverters, making it ideal for centralized control in utility-scale and large commercial solar farms.

• Comprehensive System Protection: Equipped with high-quality molded case circuit breakers (MCCBs) for each input branch and a main output breaker. These provide reliable overcurrent and short-circuit protection for individual inverter strings and the main line. An integrated lightning surge protective device (SPD) shields the entire system from damaging voltage spikes caused by atmospheric events.

• Robust and Durable Enclosure: The box is constructed with a heavy-duty, corrosion-resistant material (such as galvanized steel or high-grade engineering plastic) and features a high IP rating (e.g., IP65). This ensures total protection against dust, water jets, and harsh environmental conditions, guaranteeing long-term reliability outdoors.

• Enhanced Safety and Operational Control: The design prioritizes operator safety with clear labeling, secure isolation points, and a logical layout for easy access. The centralized design allows for quick and safe disconnection of individual inverter strings or the entire array for maintenance or emergency purposes.

• Streamlined Installation and Maintenance: A well-organized internal layout with pre-drilled mounting points and standardized busbars simplifies the wiring process, reducing installation time and labor costs. Its design facilitates straightforward troubleshooting and future system expansions.

• Seamless System Integration: As a dedicated Solis component, it is perfectly compatible with Solis three-phase inverter series, ensuring optimal performance and a cohesive system architecture. It serves as the crucial link between the inverters and the next distribution tier.
