Victron BlueSolar PWM-Light 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).

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

• Three-stage charging (bulk, absorption and float) with fixed values: absorption at 14.2 V / 28.4 V and float at 13.8 V / 27.6 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, lighting control with timer and low-voltage disconnect: it turns off at 11.2 V / 22.4 V to protect the battery.
• A small two-digit display lets you configure the load output and the timer quickly.
• 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.
