SCMM-12/12 DC1500V PV Combiner Box

The SCMM-X/Y photovoltaic combiner box is designed to support a maximum input voltage of DC 1500V and is compatible with photovoltaic inverter products to form a complete photovoltaic power generation system solution. Through RS485 communication with the host computer, its main functions include real-time monitoring of the current in each branch of the DC system, the temperature of the cabinet, the status of the lightning arrester, and the status of the DC switch, etc. It can achieve automatic alarm for abnormal conditions and real-time detection of harmful arcs in the DC circuit. Once harmful arcs are detected, an alarm signal will be sent immediately to directly drive the trip unit and cut off the faulty circuit, thereby effectively preventing potential safety hazards such as fires caused by arcs.

  • Real-Time Monitoring: Continuously monitors the generation current, voltage, temperature, lightning arrester status, DC circuit breaker status, and DC arc fault status of each photovoltaic string within the combiner box, and communicates with the host computer via RS485.
  • Data Visualization: For the detected current, temperature, switch status, and other data, the module can display a histogram interface through an LCD, allowing for intuitive reading of current and other data.
  • Configurable Alarm: According to the actual needs of the site, it can be configured to turn on or off its alarm and shunt release functions (by default, only the arc alarm and trip functions are turned on). When an alarm is triggered, the interface will pop up alarm information.
  • IP65 Rating: Achieves an IP65 protection rating, offering dustproof, moisture-proof, and salt fog resistance, meeting the requirements for outdoor installation.
  • Simultaneous Connection: Capable of simultaneously connecting multiple photovoltaic module strings, each equipped with a dedicated photovoltaic fuse to ensure safety in case of a string failure.
  • High-Voltage Surge Protector: Equipped with a photovoltaic-specific high-voltage surge protector, providing protection for the positive and negative poles of the busbar to ground after current combination, with a continuous operating voltage of up to 1500VDC.
  • Advanced Busbar Technology: Uses a unique bent copper busbar structure technology, with a full copper busbar design for the main circuit, enhancing the DC withstand voltage value.
  • Flexible Customization
  • Customizable Options: Can be customized according to user requirements for box material, size, and other functions, offering private-label customization options to meet specific needs.
