1500V DC Solar PV Array String Combiner Box
This combiner box merges up to 8 PV DC input channels into one output, with each channel equipped with a fuse. It includes a solar DC disconnect switch and surge baffle to prevent overvoltage.





Technical Specifications
Overview
High-Voltage DC String Consolidation
The SMC Series DC Combiner Box is designed to streamline solar PV installations by combining multiple array strings into a single output. Engineered for high-voltage systems up to 1500V DC, it significantly simplifies wiring between the DC distribution cabinet and the inverter. This pre-installed solution reduces installation time and error susceptibility while providing robust protection for grid-tied and off-grid solar power systems.
