Victron BlueSolar PWM-Pro 12/24V-5A

Original price was: $59.00.Current price is: $53.64. (inc. GST)


The Victron BlueSolar PWM-Pro 12/24V-5A is a solar charge controller designed to regulate the charging of batteries in off-grid solar power systems. It supports both 12V and 24V battery systems and has a maximum charge current of 5 amps.

PWM-Pro stands for Pulse-Width Modulation Professional, which is a type of charge regulation that gradually reduces the charging current as the battery voltage approaches its maximum charge level. This helps to prevent overcharging and prolongs the life of the battery.

The BlueSolar PWM-Pro has a range of features, including:

  • 5-stage charging: Bulk, absorption, float, equalization, and storage
  • LED indicators to show charging status and battery level
  • Automatic voltage detection for 12V or 24V systems
  • Overload and short-circuit protection
  • Temperature compensation to adjust the charging voltage based on the ambient temperature

Overall, the Victron BlueSolar PWM-Pro 12/24V-5A is a reliable and efficient solar charge controller that is suitable for small to medium-sized off-grid solar power systems.

Victron Bluesolar pro PWM solar controller:

Victron's range of  PWM and MPPT charge controllers are both widely used to charge batteries with solar power.

The PWM controller is in essence a switch that connects a solar array to the battery. The result is that the voltage of the array will be pulled down to near that of the battery.

A PWM controller is not a DC to DC transformer. The PWM controller is a switch which connects the solar panel to the battery. When the switch is closed, the panel and the battery will be at nearly the same voltage. Assuming a discharged battery the initial charge voltage will be around 13 V, and assuming a voltage loss of 0,5 V over the cabling plus controller, the panel will be at Vpwm = 13,5 V.


The voltage will slowly increase with increasing state of charge of the battery. When absorption voltage is reached the PWM controller will start to disconnect and reconnect the panel to prevent overcharge (hence the name: Pulse Width Modulated controller).


The BlueSolar PWM-Pro series is ready for use with its default settings. It also is fully programmable:


-With help of a computer and software (available free of charge from Victron website)

-With the dedicated BlueSolar Pro Remote Panel.



  • -Lighting control function, fully programmable.
  • -Three stage battery charging (bulk, absorption, float), fully programmable.
  • -Integrated battery monitor function (Remote Panel needed to display state of charge).
  • -Load output with low voltage disconnect and manual control (default setting).
  • -Optional external temperature sensor.
  • -Load output protected against over load and short circuit.
  • -Protected against reverse polarity connection of the solar array and/or battery.
