Product overview This MPPT solar charge controller provides efficient, adaptive charging for 12 volt and 24 volt battery systems. Housed in a durable plastic case with a compact footprint of 170 x 95 x 40 mm, it offers selectable rated discharge currents of 10A, 20A, or 30A and includes a 5V 2A USB output for charging small devices. Working temperature range is minus 35 to plus 60 degrees C. Color: 20A. Size: A. Package includes one solar charge controller. Key benefits Higher charging efficiency: Advanced MPPT tracking continuously optimizes panel output for faster, more effective battery charging. Twoway tracking maintains performance during changing light conditions. Reliable protection: Multiple builtin protection functions guard against common faults and are selfrecovering once the fault is cleared, reducing risk of controller damage. Accurate monitoring: Industrialgrade main control chip with 16level AD sampling offers precise, realtime measurement of temperature and charging current, making system performance and power generation easy to read. Flexible configuration: Color LCD display and adjustable charge and discharge parameters allow the controller to be tailored to a wide range of battery characteristics, improving compatibility and conversion rates. Practical output: Integrated 5V 2A USB port provides convenient power for phones and small electronics without additional adapters. Key specifications Type: MPPT Battery voltage: 12V/24V adaptive Rated discharge current: 10A, 20A, or 30A optional USB output: 5V 2A Working temperature: 35 to +60 degrees C Material: Plastic Size: 170 x 95 x 40 mm Package included: 1 Solar Charge Controller Core features explained AutoMPPT tracking charging: Continuously detects panel and battery conditions to maximize energy harvest and maintain stable charging. Industrialgrade control and sampling: 16level AD sampling ensures finegrained measurements of temperature and current for accurate status reporting and safer operation. Multiple protections with selfrecovery: Overcharge, overdischarge, short circuit, reverse connection, and other protective functions respond automatically and recover when faults are resolved. Large color LCD: Clear display of charging and discharging parameters; settings are adjustable to match battery characteristics for better system performance. Wide ambient tolerance: Operates reliably across a broad temperature range, suitable for outdoor or semiexposed installations with appropriate enclosure. Compatibility and suitability Adapts automatically to 12V or 24V battery systems, with adjustable charge and discharge settings to suit different battery characteristics. Compact dimensions and plastic construction make the unit easy to mount in small control enclosures, panels, or equipment boxes. Practical use scenarios 1) Offgrid cabin or cottage: Manage solar panels and batteries for lighting, small appliances, and device charging while maintaining efficient energy conversion and automatic protection. 2) Mobile applications such as RV or caravan: Use the controller to charge onboard batteries from roofmounted solar panels and keep electronics powered through the integrated USB port. 3) Remote equipment and lighting: Power and protect batteries for security lights, telemetry devices, or monitoring equipment where dependable MPPT tracking and selfrecovering protections reduce maintenance. What you get One MPPT solar charge controller with the above specifications and features, ready to integrate into small solar power systems. This controller is intended for users who need reliable MPPT charging performance, flexible parameter control, and builtin protections in a compact, easytoinstall unit.
