Key benefits and why you need this product Fast, convenient charging: Dual USB outputs let you charge two phones or devices at the same time, delivering reliable power for quick top-ups from your solar system or generator. Stable, reliable performance: An industrial-grade microcontroller manages charging and system operation, keeping the controller stable in cold conditions, high temperatures, and humid environments. Smart, automatic charging: The controller automatically recognizes common system voltages and intelligently adjusts charging behavior for safe, efficient battery charging. Protection you can trust: Built-in safeguards prevent overcharge, overdischarge, overload, short circuit, and damage from reverse connection. Features and important attributes Function: Solar charge controller with dual USB output for powering mobile devices while managing PV-to-battery charging. Compatibility: Designed for typical 12 V systems and automatically handles standard system voltages; works with solar panels, solar generators and battery banks. Performance: Industrial microcontroller provides consistent regulation and reliable operation in challenging environmental conditions. Safety: Comprehensive protections include overcharge, overdischarge, overload, short-circuit and reverse-connection protection to extend battery life and protect connected devices. Build and form: Robust, field-ready design made for use with solar generators and off-grid systems (compact footprint suitable for installations where space is limited). How it solves common problems Eliminates unpredictable charging: Instead of relying on raw panel output, the controller provides stable, regulated charging that protects batteries and devices from voltage spikes and improper charging cycles. Reduces device downtime: Dual USB ports allow simultaneous charging of phones and accessories directly from your solar setup. Withstands harsh conditions: The industrial microcontroller and durable design ensure operation in cold, hot, or humid environments where lesser controllers may fail. Typical use scenarios 1) Off-grid cabins or tiny homes: Manage a 12 V solar battery bank while charging phones and small electronics at the same time, with automatic voltage recognition and robust protections to preserve battery health. 2) RVs, boats and campers: Integrate the controller into a mobile solar setup to ensure stable charging on the road or water, and use the built-in USB ports for convenient device charging without extra adapters. 3) Portable solar generators and emergency kits: Pair with a portable solar generator to control panel charging and provide dependable USB power for phones, radios, and other essential devices during outages or fieldwork. What to expect in everyday use Simple connection: Plug your solar panel, battery and load according to standard wiring; the controller handles voltage detection and smart charging automatically. Safe operation: Active protection features minimize the risk of battery damage and protect connected devices from faults. Durable performance: Designed to run reliably in varying temperatures and humid conditions thanks to the industrial microcontroller. If you need a compact, dependable solar charge controller that also powers mobile devices, this unit provides smart voltage recognition, stable operation across tough environments, dual USB convenience, and comprehensive safety features.
