Regulator Victron BlueSolar DUO 12 / 24V 20A

Regulator Victron BlueSolar DUO 12 / 24V 20A

The Bluesolar DUO PWM is a 3-speed charge controller that can charge two battery packs. The controller is equipped with a Solar connection and two battery outputs.

PWM solar regulators protect your batteries from discharges and overcharging, ensuring that they last longer.

The range uses "Pulse Width Modulation" (PWM) pulse voltage control together with a multi-step load control algorithm. This results in a higher charge and improves the performance of the battery. The filtered PWM power control system utilizes highly efficient and reliable MOSFET power transistors. The fully automatic temperature compensation of the charging voltage is made to improve the charge control and battery performance. The battery temperature sensor, which is optional, is developed for long-term reliability.

Improves battery charge (faster and more efficient charging)
Display of the state of charge of the battery by led on three levels.
Three stages of battery charging (bulk, absorption, float).
Overcurrent protection
Protection against short circuits.
Protection against reverse polarity connection of solar panels and / or battery.
Disconnection of the output at reduced voltage load.
Battery overload protection by shutting off the solar module when the battery is full.
