The Victron BlueSolar PWM-Pro 12/24V-20A

Original price was: $118.00.Current price is: $107.27. (inc. GST)

 

The Victron BlueSolar PWM-Pro 12/24V-20A is a solar charge controller designed for use with 12V and 24V systems. It is a Pulse Width Modulation (PWM) controller, which means it regulates the charging current by adjusting the pulse width of the charge current to the battery.

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).

Programmable:

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.

 

Features:

-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.
