SCDB-3/1 AC Distribution Cabinet

The SCDB PV AC Distribution Cabinet is an essential component in photovoltaic (PV) string inverter power generation systems, designed to provide power protection between string inverters and AC distribution cabinets or step-up transformers. By consolidating the output currents from multiple inverters, this device simplifies the wiring between string inverters and step-up transformers, thereby enhancing system reliability and facilitating maintenance.

  • High Protection Rating: The cabinet achieves an IP65 protection rating, offering protection against water ingress, dust, ultraviolet radiation, and salt fog corrosion, thus meeting the requirements for outdoor installation.
  • Multiple Input Channels: It can simultaneously connect to multiple outputs from string inverters, with each input line protected by a thermal-magnetic circuit breaker, and the rated voltage reaching up to AC 1140V.
  • Intelligent Monitoring: Equipped with an integrated meter for data acquisition, it enables local or remote data monitoring via the RS485/ModBus-RTU communication protocol.
  • High-Voltage Lightning Protection: It is fitted with a dedicated high-voltage surge arrester to provide overvoltage and lightning protection between three phases, with a working voltage of above AC 1140V.
