Victron BlueSolar PWM 12/24/48V Charge Controller

Victron BlueSolar PWM 12/24/48V Charge Controller Description:

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.

• Liquid Crystal Display
• Two 5 Volt USB outputs
• Lighting control function, fully programmable  
• Three stage battery charging (bulk, absorption, float), fully programmable
• Load output with low voltage and manual disconnect (programmable)
• Load output protected against over load and short circuit
• Protected against reverse polarity connection of the solar panels and/or battery
