AC220V-800V 2 String PV Combiner Box IP65 Photovoltaic Junction Box
IP65 220-800V AC PV Combiner Box 1-N String Inverter
YT-AC PV combiner box is primarily used for the string-level combiner of central photovoltaic grid-connected power generation systems. It is connected between the string-level grid-tied inverter and the grid metering cabinet. The product features protections such as input lightning protection and system overcurrent. The application of this product reduces the need for long-distance transmission of large cables, resulting in cost reduction and improved system efficiency for users. The product has obtained industry-standard CCC certification and IS09001 quality management system certification.
All components are sourced from well-known domestic or international brands, with authoritative certifications and complete qualifications. The exposed live parts inside are protected by flame-retardant, antistatic, and high-temperature-resistant transparent covers. The input and output circuit breakers are vertically installed in a forward direction and laid flat in the enclosure to ensure proper wiring and avoid misconnections. The main circuit adopts copper busbar connections with a corrosion-resistant and oxidized tin-plating process on the surface. Each phase wire is color-coded according to industry standards for clear identification. An optional intelligent monitoring system is available to monitor system voltage, main circuit current, switch status, and lightning protection status. The product is suitable for various voltage levels commonly used in the industry, such as 380Vac, 480Vac, and 540Vac. It is designed with a rainproof cover for outdoor installation.
