SCMM-16/1 DC1500V PV Combiner Box

The SCMM-X/Y PV combiner box is designed with a maximum input voltage of DC 1500V, making it compatible with photovoltaic inverters to form a complete photovoltaic power generation system solution. By connecting photovoltaic arrays through the combiner box, the number of cables between photovoltaic strings and inverters is reduced, lowering system costs and enhancing system reliability. With the use of a photovoltaic combiner box, users can group a certain number of identical photovoltaic modules into an array based on the DC voltage range acceptable to the inverter. Several strings can then be connected to the combiner box, and the output is facilitated through a surge protector and circuit breaker, simplifying the connection to centralized inverters.

  • High Protection Rating: Achieves an IP65 protection rating, offering dustproof, moisture-proof, and salt fog-resistant features, meeting the requirements for outdoor installation.
  • Multi-String Input: Capable of simultaneously connecting multiple photovoltaic module strings, each equipped with a dedicated photovoltaic fuse to ensure safety in the event of a string failure.
  • Intelligent Monitoring: Incorporates an internal monitoring module, utilizing high-end MCU processors and current/arc sensors. Data monitoring can be performed locally or remotely via the RS485/ModBus-RTU communication protocol.
  • High-Voltage Surge Protection: 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.
  • Reliable Structure: Employs 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: Can be customized according to user requirements for box material, size, and other functions, offering private-label customization options.
