66kW SiC MPPT PV Boost Module
BDC66K102PV • 3‑Channel Independent MPPT • 99.2% Peak Efficiency • SiC Technology
📖 Product Overview
MPPT (Maximum Power Point Tracking) continuously monitors PV module voltage and tracks the maximum voltage‑current point (VI) to ensure the PV array always operates at peak power. Under varying irradiance and temperature, MPPT efficiently converts solar DC into adjustable DC voltage. Compared to conventional controllers, tracking efficiency is improved by 50%, significantly boosting energy harvest.[reference:0][reference:1]
This MPPT module employs third‑generation SiC power semiconductors and achieves a peak conversion efficiency of 99.2%.[reference:2] It supports RS485, CAN, Ethernet, and dry‑contact communication for seamless integration with third‑party EMS, BMS, and host systems.[reference:3] The module is designed for DC‑coupled storage architectures and is widely used in DC microgrids, PV‑storage‑flexible, and PV‑storage‑diesel hybrid systems — the premier choice for commercial & industrial (C&I) energy storage.[reference:4]
