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

Original price was: $43.02.Current price is: $38.18. (inc. GST)

The Victron BlueSolar PWM-Light 12/24V-5A is a compact and efficient solar charge controller designed for small-scale off-grid solar systems. It can handle up to 5 amps of current and works with both 12 and 24 volt battery systems. The controller uses Pulse Width Modulation (PWM) technology to regulate the charging of the battery and prevent overcharging and damage to the battery. It has an easy-to-use interface with LED indicators that show the status of the charging process. The BlueSolar PWM-Light is also designed with a low voltage disconnect feature that protects the battery from deep discharge. It is a reliable and cost-effective solution for small solar systems such as lighting, small appliances, and irrigation pumps.

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 array and/or battery.
