This 3-stage solar charge controller delivers efficient, reliable charging and battery protection for small 6V and 12V solar systems. It regulates voltage and current, uses PWM technology for stable charging, and includes selectable discharge modes and clear LED status indicators for simple operation and monitoring. Key benefits Protects battery life: 3-stage charging and regulated current reduce stress on batteries, helping extend their usable life. Stable, safe charging: Pulse width modulation (PWM) provides a steady charging current while preventing overcharging, over-discharge, and short circuits. Flexible compatibility: Works with both 6V and 12V solar panels, supporting up to 60W for 6V panels and up to 120W for 12V panels to match a variety of small solar setups. Easy to use and install: Compact, user-friendly design with a DIP switch for mode selection and LED indicators that clearly show controller status. Features 3-stage charging for efficient and safe battery charging PWM (pulse width modulation) charging control for stable current and improved battery performance Overcharge, over-discharge, and short-circuit protection Compatible with 6V and 12V systems; supports up to 60W (6V) and 120W (12V) DIP switch selectable discharge modes: pure light control or light control plus timing mode LED indicators for power, charging and load status Designed for straightforward wiring and installation Typical applications Garden and pathway lighting powered by small solar panels Remote or off-grid small lighting systems for sheds, cabins, or workshops Auxiliary lighting or electronics on RVs, boats, or trailers where 6V/12V panels are used How it solves common problems Prevents battery damage from improper charging by regulating voltage and current and using a controlled charging cycle Stops system downtime caused by over-discharge or short circuits with built-in protections Simplifies configuration and monitoring with a DIP switch for mode selection and visible LED status lights Operation notes Select 6V or 12V operation and the desired discharge mode with the DIP switch Confirm panel wattage does not exceed 60W for 6V or 120W for 12V systems Use the LED indicators to monitor charging and load status during normal operation This controller is suited to small solar installations that need reliable charging control, battery protection, and simple operation without complex setup.
