Solar charge controller that delivers stable, efficient charging and protects both your battery and devices Key benefits Reliable, efficient charging: Built-in industrial microcontroller and a full 3-stage charge management system (bulk, absorption, float) optimize battery life and charging efficiency. Protects your system and devices: Dual MOSFET reverse-current protection prevents backflow, reduces heat generation and extends component life. Convenient device charging: Two USB outputs let you charge phones and small electronics directly from the controller; combined USB output supports up to 5 A, sufficient to charge Apple phones and other high-current devices. Safer operation: Multiple integrated protections reduce risk of failure and downtime. Core features Panel charge controller with an industrial-grade microcontroller for stable, repeatable charge control. Full 3-stage charging management to maximize battery health and charging speed. Dual MOSFET reverse-current protection for improved safety, lower heat and longer service life. Dual USB outputs for fast and convenient charging of mobile devices; maximum combined USB output current 5 A. Built-in protections: short-circuit protection, open-circuit protection, reverse-polarity protection and overload protection to safeguard the solar system and connected devices. Compatibility and performance Designed to work with solar panels and batteries in typical off-grid or auxiliary power setups. USB outputs are compatible with smartphones, tablets and other USB-powered devices; supports higher-current devices such as Apple phones up to the specified 5 A output limit. Industrial microcontroller ensures consistent charging behavior under varying solar input conditions. Practical use scenarios Weekend camping or RV trips: Manage a small solar array to keep a leisure battery healthy while charging phones, lights and small appliances via the USB ports. Emergency backup power: Maintain battery readiness and safely charge essential devices during a power outage. Small off-grid systems: Provide controlled charging and device charging for garden sheds, boats, or remote sensors where reliable battery maintenance and device charging are required. What you can expect Efficient charging that extends battery life and reduces the chance of premature battery failure.
