Product Details
AC combiner box
Overview
This product is primarily used for busbar connections in string inverters within centralized photovoltaic grid-connected power generation systems. It is connected between the string grid-connected inverter and the grid-connected metering cabinet. The product features input lightning protection and system overcurrent protection. Its application reduces the need for extensive long-distance cable transmission, lowering costs and improving system efficiency for users. The product has obtained industry standard certifications including CCC certification, CE certification, and ISO 9001 Quality Management System certification.
Key Features
All components utilize renowned domestic/international brands with authoritative certifications. with complete qualifications. Internal exposed live parts are protected by flame-retardant, anti-static, and high-temperature-resistant transparent cover plates. Incoming and outgoing circuit breakers are vertically installed and laid flat within the enclosure, with one-to-one wiring correspondence to prevent misconnection. Busbars use copper bus connections with anti-corrosion and anti-oxidation tin-plating treatment. Each phase line employs industry-standard color coding for clear visibility. Optional smart monitoring system (system voltage, busbar current, switch status, surge protection status); Suitable for various industry voltage levels: 380Vac, 480Vac, 540Vac; Rainproof cover design for outdoor installation. Supports customization for special requirements and functions.
