What a feature packed Solar Controller! Using 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 supporting 12V solar arrays up to 580W or 24VDC arrays up to 1170W, it suits a huge range of applications. 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 8AWG. Intelligent and optimum MPPT charging algorithm 3-stage charging Displays real-time energy stats, operational and fault message Temperature sensor input for battery charging compensation Low-voltage disconnect/reconnect WiFi support (module sold separately)
