10A PWM Solar Charge Controller for 12V/24V Systems This compact solar controller delivers reliable, efficient charging and strong protection for small offgrid systems. It automatically detects battery voltage, supports 12V or 24V systems, and combines PWM charging with dual antibackflow MOS tube design to reduce heat and improve charge efficiency. The large LCD display and adjustable parameters make setup and monitoring simple, while multiple builtin protections help keep batteries and connected devices safe. Key benefits Efficient charging: PWM automatic tracking ensures charging efficiency and continuous detection during charging to keep your battery healthy. Strong safety and fault recovery: Builtin protections include overheating, overcurrent, short circuit, open circuit, troubleshooting, and automatic controller recovery to minimize downtime. Low heat and antibackflow design: Dualway MOS tube antibackflow circuit and power charging mode lower heat generation and improve longterm reliability. Easy monitoring and control: Largescreen LCD shows status and values; adjustable charge and discharge parameters with poweroff memory preserve settings after power loss. Versatile output: Dual USB output 5V/2A provides convenient charging for mobile phones and small devices.
