1. Advanced MPPT maximum power point tracking technology with a maximum efficiency of 98%, helping to optimize solar panel energy utilization and reduce system costs. 2. High-quality components ensure reliable performance and high system conversion efficiency, up to 97%. 3. Ultra-fast maximum power point tracking speed while maintaining high efficiency. 4. Equipped with a 4-digit digital display that shows real-time data including solar panel voltage, charging current, and battery voltage, providing clear and convenient monitoring of the charging status. Allows users to manually set battery voltage and charging parameters. 5. Wide operating voltage range for the maximum power point of the photovoltaic array: 12V50V. 6. Direct parameter display design for dynamic monitoring of equipment operation data and status, including solar panel voltage, charging current, and battery voltage. 7. Utilizes power directly from solar panels; standby power consumption is zero. The system operates only when sufficient solar power is available and does not run at night. 8. Supports manual setting of battery voltage and charging parameters via control buttons. Compatible with various battery types, including lithium-ion, LiFePO4, nickel-metal hydride, lead-acid, and gel batteries. 9. Includes a child lock function to prevent accidental changes to settings due to unintended button presses. 10. Requires proper connection sequence: connect the battery first, then use the included fuse to connect to the battery. Observe correct polarityreverse connection may damage the unit. 24/36/48/60/72V MPPT Solar Charge Controller with Anti-Reverse Connection Protection Features: MPPT high-efficiency charging method with up to 97% charging efficiency. Overvoltage, overcurrent, and reverse polarity protection for enhanced safety and reliability.
