š Product Overview
MPPT (Maximum Power Point Tracking) continuously monitors PV module voltage and tracks the maximum voltageācurrent 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 thirdāgeneration SiC power semiconductors and achieves a peak conversion efficiency of 99.2%.[reference:2] It supports RS485, CAN, Ethernet, and dryācontact communication for seamless integration with thirdāparty EMS, BMS, and host systems.[reference:3] The module is designed for DCācoupled storage architectures and is widely used in DC microgrids, PVāstorageāflexible, and PVāstorageādiesel hybrid systems ā the premier choice for commercial & industrial (C&I) energy storage.[reference:4]

ā Frequently Asked Questions
š¹ Can the three MPPT channels operate independently with different PV modules?
Yes. Each channel has independent voltage/current sensing and boost circuitry, allowing connection to PV arrays with different power ratings or voltage levels ā ideal for multiāorientation or mixedācapacity installations.
š¹ What are the advantages of SiC over traditional IGBTābased MPPT?
Thirdāgen SiC devices offer ultraālow switching losses, achieving 99.2% efficiency ā 1.5ā2.5% higher than IGBT. This translates to more annual yield, smaller heatsink requirements, more compact dimensions, and lower longāterm O&M costs.
š¹ Which communication protocols are supported? Can it interface with thirdāparty EMS?
Standard RS485, CAN, Ethernet, and dry contact with Modbus RTU/TCP and dedicated storage protocols. Seamlessly connects to thirdāparty BMS, EMS, and remote monitoring platforms.
š¹ Can the module eliminate the PV combiner box?
Yes. The three MPPT inputs can directly connect to PV strings without a frontāend combiner box, reducing hardware losses, system cost, and wiring complexity.
š¹ Is custom power / voltage rating available?
Yes. Imax Power offers full projectābased customization ā MPPT channel count, input/output voltage ranges, rated power, communication protocols, and thermal solutions. Full technical documentation provided.
