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-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 13V, and assuming a voltage loss of 0.5 V over the cabling plus controller, the panel will be at V PWM = 13.5V.

The voltage will slowly increase with increasing state of charge of the battery. When the 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 the help of a computer and software (available free of charge from the Victron website)
• With the dedicated BlueSolar Pro Remote Panel.

More Product 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 overload and short circuits.
• Protected against reverse polarity connection of the solar array and/or battery.
• Day/night timing options.
