1. Advanced Solar Charge Controller: This 20A solar charge controller features an LCD display for realtime monitoring of your 12V/24V solar system performance. With MPPT for PWM charging mode, it maximizes energy harvest from your solar panels while maintaining battery health. The userfriendly interface allows easy parameter adjustment and onebutton operation for load control and factory reset when needed. 2. Comprehensive Protection System: Your battery investment is safeguarded with multiple protections, including reverse discharge protection, reverse polarity protection, undervoltage protection, and overload/shortcircuit protection. These features work together to extend battery life and prevent damage to your solar power system components, ensuring peace of mind during operation. 3. Smart Battery Management: Experience optimized charging with automatic temperature compensation, adjusting charge parameters based on environmental conditions (4 mV/cell/°C). The controller maintains a float voltage of 13.8V for 12V systems or 27.6V for 24V systems, while providing undervoltage protection at 10.6V/21.2V and recovery at 12.6V/25.2V to keep your batteries in peak condition. 4. VERSATILE COMPATIBILITY: This solar controller works with a wide range of solar panels, handling maximum opencircuit voltages of 18V24V for 12V systems and 36V48V for 24V systems (not exceeding 48V). Its compact design (16.5 × 9.5 × 5 cm) enables easy installation in various locations, making it ideal for RVs, boats, cabins, and offgrid solar setups.
