Victron BlueSolar PWM-LCD&USB 12/24V-5A (PWM Charge Controller)

In a nutshell

5 A PWM solar charge controller for 12 or 24 V batteries (detects the voltage automatically), with LCD screen and two USB ports.

A PWM is the simplest solar charge controller: it connects the panel directly to the battery and regulates the charge so it does not overcharge.

When it is suitable

• At 12 V, with a 36-cell panel.
• At 24 V, with a 72-cell panel or two 36-cell panels in series.
• It is not for large panels: for those an MPPT charge controller is used.

About this model

• The liquid crystal display lets you view and adjust the configuration.
• Three-stage programmable charging (bulk, absorption and float): absorption at 14.4 V / 28.8 V and float at 13.7 V / 27.4 V.
• It accepts up to 28 V from the panels in 12 V systems and 55 V in 24 V systems.
• Load output for lights or other loads, with manual control, timer, programmable lighting control and low-voltage disconnect: it turns off at 11.2 V / 22.4 V to protect the battery.
• Two USB ports of 5 V (2 A).
• Protected against reverse polarity of the panel and the battery (with fuse), against short circuit and overload on the load output, and against excess temperature. It consumes only 10 mA.
