This high current charger uses Maximum Power Point Tracking (MPPT) for maximum efficiency and charge rate. It can charge 12V, 24V, 36V or 48V lead acid (sealed, gel or flooded) or 12V lithium battery banks, and supports 12V solar arrays up to 700W or 24VDC arrays up to 1400W. It is recommended for battery capacities 50Ah and above, and features three timer programs, three stage charging, including constant voltage charging, and a backlit LCD to diplay real-time feedback on battery voltage, load voltage, PV voltage, time, etc. An external temperature probe is also supplied to adjust the float voltage according to the temperature when charging SLA batteries. The integrated Wi-Fi enables you to remotely access the controller using an app on your Smartphone to keep an eye on the system, and two USB ports are provided to charge your USB gadgets. The fanless design is built into a durable case for permanent installation with heavy-duty screw terminals for cabling up to 6AWG. Safety features include over-voltage, low-voltage protection, reverse connection, short-circuit, over-current, and over-temperature protection.
