Victron BlueSolar PWM-LCD&USB 12/24V-20A

The BlueSolar PWM 12/24V 20A Solar Charge Controller is a reliable and user-friendly solution for regulating solar energy to charge 12V or 24V battery banks. Equipped with a built-in LCD display, two 5V USB ports, and programmable load output control, this controller provides flexible and intelligent battery management for small solar systems.

Featuring three-stage charging (bulk, absorption, float), low-voltage load disconnect, and full protection against reverse polarity, short circuit, and overload, the BlueSolar PWM ensures safe and efficient battery operation. The controller is ideal for off-grid solar setups, RVs, boats, and small solar installations.
