20A MPPT Solar Charge Controller for Lithium or SLA Batteries

Overview

Uses Maximum Power Point Tracking (MPPT) for maximum efficiency and charge rate. Able to charge lead-acid (sealed, gel, or flooded) or lithium battery banks between 8V to 32V, and supports 12V solar arrays up to 260W or 24VDC arrays up to 520W. It features bulk, constant, and float charge stages for rapid, efficient, and safe battery charging, with feedback on charge status, current, voltages, etc., shown on the LCD screen. Built into a durable case for permanent installation with heavy-duty screw terminals for cabling up to 10AWG.

Note:
Charge Mode F04 is for Lithium 12.8V and F08 is for 25.6V Lithium batteries. If your controller does not have these modes, purchase MP3746 to program this controller with details from your battery's data sheet.
