Victron BlueSolar PWM DUO 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
- Charges two separate batteries
- Programmable charge current ratio
- External Temperature sensor
