Solar Charge Controller Printed Circuit Assembly from China
This printed circuit assembly (PCA) contains the rectifying diodes, MOSFETs, and control ICs for a solar MPPT charge controller that converts variable DC input from solar panels to stable battery charging voltage. It falls under HTS 8504.90.75.00 as a PCA component of a static converter used in renewable energy systems. The assembly is designed for surface-mount integration into compact solar controllers.

Import Tips
• Verify the PCA performs power conversion functions like rectification or regulation to avoid reclassification as general PCBs (8534)
• Include detailed circuit schematics and bill of materials in documentation
• Ensure RoHS compliance certification for electronics imports
