Advanced MPPT maximum power point tracking technology with a peak efficiency of 98%, optimizing energy harvest from the solar panel and improving overall system efficiency. High-quality components ensure reliable performance and a maximum conversion efficiency of 97%. Ultra-fast MPPT tracking speed maintains high efficiency under varying sunlight conditions. Equipped with a 4-digit digital display that shows real-time data including solar panel voltage, charging current, and battery voltage for clear monitoring of the charging status. Allows users to manually set battery voltage and charging parameters via control buttons. Wide operating voltage range for the photovoltaic array: 12V to 50V. Direct parameter display dynamically presents equipment operating data and status, including panel voltage, charging current, and battery voltage. Features power-taking technology from solar panels, resulting in zero standby power consumption—system power is fully supplied by the solar panel, and the controller does not operate at night. Supports manual configuration of battery voltage and charging settings, compatible with various battery types including lithium, LiFePO4, nickel-metal hydride, lead-acid, and gel batteries. Includes a child lock function to prevent accidental changes to settings due to unintended button presses. Requires proper connection sequence: connect the battery first, then connect the solar panel. Integrated fuse protection; observe correct polarity to avoid reverse connection which may damage the unit. Designed for use with 24V, 36V, 48V, 60V, and 72V battery systems. MPPT charging method delivers up to 97% charging efficiency. Overvoltage, overcurrent, and reverse polarity protection included for enhanced safety and durability.
