This solar panel charge controller combines industrial-grade control, efficient charging, and robust protection to keep small solar systems reliable and easy to use. Key benefits - Reliable, automatic charging: Built-in industrial microcontroller and a fully 3-stage PWM charge management system optimize charging to extend battery life and maintain stable performance. - Easy setup and monitoring: Large LCD display lets you read status and adjust parameters quickly without guesswork. - Safer, cooler operation: Dual Mosfet reverse current protection reduces heat production and improves operational safety compared with simple single-MOSFET designs. - Convenient device charging: Dual USB outputs provide up to 5A total for powering or charging phones, tablets, and USB devices directly from the system. - Durable, protected system: Multiple built-in protections guard your system against short circuit, idle, reverse connection and overload conditions, increasing safety and longevity. What it does and why it matters - Manages panel to battery charging using a three-stage PWM algorithm (bulk, absorption, float) to reduce overcharge and improve battery health. - Prevents power loss back into the panels at night and lowers component temperature through dual Mosfet reverse current protection, reducing thermal stress and improving reliability. - Gives direct, convenient USB power for everyday devices, eliminating the need for additional adapters. Compatibility and performance notes - Designed for use with solar panels and associated battery systems as the charge-management component in small off-grid or auxiliary installations. - Large LCD simplifies monitoring and parameter adjustments without external tools. - Dual USB outputs deliver up to 5A combined, suitable for charging common USB devices while the controller manages panel/battery charging. - Built-in protections (short circuit, idle, reverse, overload) help ensure safe operation and reduce the risk of equipment damage. Typical applications - Remote cabin or shed: Manage a PV panel and battery to provide reliable lighting and device charging with clear monitoring and protections. - Recreational vehicle or boat: Compact charge control and dual USB ports allow device charging and battery maintenance while limiting heat and reverse current losses. - Small off-grid systems for workshops or garden equipment: Keep batteries in good condition with 3-stage PWM charging and automatic safety features.
