Victron BlueSolar PWM-Light 12/24V-30A

Original price was: $93.00.Current price is: $84.55. (inc. GST)

The Victron BlueSolar PWM-Light 12/24V-30A is a high-quality charge controller designed for use in off-grid solar systems. It regulates the voltage and current from the solar panel to the battery bank to ensure safe and efficient charging. With a maximum current rating of 30 amps, this controller is suitable for both 12V and 24V systems and can handle larger solar arrays. It features a low voltage disconnect function to protect the battery from over-discharging, and a load output that can be used to power DC loads directly from the battery. The Victron BlueSolar PWM-Light 12/24V-30A is easy to install and operate, and is a reliable and durable option for medium to large-sized solar systems.

Victron Bluesolar light 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).


Load output with low battery voltage disconnect function.

Lighting control function, one timer only.

Two digit seven segment display for quick and easy setting of the load output functionality, including timer setting.

Three stage battery charging (bulk, absorption, float), not programmable.

Load output protected against over load and short circuit.

Protected against reverse polarity connection of the solar arra

1) For 12V use 36 cell solar panels For 24V use 72 cell solar panels or 2x 36 cell in series

2) The controller switches to the lower float voltage level 2 hours after the absorption voltage has been reached. Whenever the battery voltage becomes lower than 13V, a new charge cycle is triggered.
