BlueSolar PWM-Light 12/24V-5A

This compact, reliable, and easy-to-use charge controller from Victron Energy is designed for small photovoltaic installations, such as off-grid systems in campers, summer houses, lighting systems, and boats. This device combines high-quality construction, robust protection, and reliable operation in even the most demanding conditions.
BlueSolar PWM-Light 12/24V-5A is a charge controller based on PWM (Pulse Width Modulation) technology that automatically detects 12V or 24V system voltage. Its design makes it ideal for low-power photovoltaic installations where reliability and simplicity are key.
Thanks to its automatic lighting on/off function based on voltage detection (e.g., at sunset and sunrise), this model is often chosen for lighting applications, including street and garden lighting. Built-in safeguards protect the battery against overcharging, deep discharge, reverse polarity, and short circuits.
