GM-D 20A MPPT Solar Charge Controller 12V/24V Auto Recognition With Dual 5V/3A USB Ports

Product Description

1. Equipped with a high-precision MPPT (Maximum Power Point Tracking) algorithm, achieving a tracking efficiency greater than 99% and a conversion efficiency up to 98%. Maximizes energy capture from solar panels even on rainy days or in frequently changing light conditions. 2. Automatically recognizes 12V-24V system voltages and is fully compatible with Gel, Sealed, Flooded lead-acid batteries, and Lithium batteries. Features a 0V lithium battery activation function and supports customizable operating parameters to flexibly adapt to various energy storage systems. 3. Features a clear and intuitive LCD screen with 4 independent buttons for real-time monitoring of PV voltage, charging current, and system status. Built-in dual USB ports (total output 5V 3A) provide convenient direct charging for mobile phones and digital devices. 4. Upgraded with large-cross-section, widely spaced wiring terminals to significantly improve insulation performance and installation reliability while effectively reducing line voltage drop and heat loss. Aluminum alloy heat sink on the back ensures stable full-power operation under high currents. 5. Integrated with multiple safety protections, including current and power limiting, short circuit, reverse polarity, and overcharge protection. Reserved RS485 communication interface allows optional WiFi/Bluetooth module connection for mobile APP remote monitoring. Specifications: 1.
