20A MPPT Solar Charge Controller for Lithium or SLA Batteries

Maximum Efficiency and Versatile Charging

• Maximum Power Point Tracking (MPPT): Ensures maximum efficiency and charge rate.
• Battery Compatibility: Charges lead acid (sealed, gel, or flooded) or lithium battery banks between 8V to 32V.
• Solar Array Support: Compatible with 12V solar arrays up to 260W or 24VDC arrays up to 520W.
• Intelligent Charging Stages: Features bulk, constant, and float charge stages for rapid, efficient, and safe battery charging.
• LCD Screen Feedback: Provides real-time feedback on charge status, current, voltages, and more.
• Durable Design: Built into a rugged case for permanent installation, with heavy-duty screw terminals supporting cabling up to 10AWG.

Important Note

• Charge Modes for Lithium Batteries:
  • Mode F04 is for 12.8V Lithium batteries.
  • Mode F08 is for 25.6V Lithium batteries.
  • If your controller does not include these modes, purchase MP3746 to program the controller using your battery's data sheet.
