Victron Energy Solar controller BlueSolar MPPT 100/20, 48V, 20A

The solar charger collects energy from the solar panels and stores it in the batteries. Using the latest and fastest technology, BlueSolar maximises this energy harvest and manages it intelligently to achieve a full charge in the shortest possible time. BlueSolar keeps the battery healthy and extends its life. By constantly monitoring the voltage and current of your solar (PV) panels, MPPT technology ensures that every drop of available energy is squeezed out of your panels and harvested for storage. Especially in the case of variable cloud cover, when the intensity of the sun's radiation is constantly changing.

Top in the industry

Victron Energy's MPPT solar controllers are among the absolute world leaders in this field. It offers ultra-fast MPPT tracking to ensure maximum possible solar gains. Especially under cloudy skies with frequent changes in light intensity, the solar gains are 30% higher compared to conventional PWM controllers or 10% higher compared to slower MPPT controllers. BatteryLife Revolutionary Charging Program - If the controller is unable to fully charge the battery in one day, the result is a gradual discharge of the battery, with each cycle continuing to exacerbate this condition. This will cause full discharge, the possibility of battery sulphation and subsequent destruction or significant loss of capacity within weeks or months.

BatteryLife's charging algorithm monitors this condition and if it starts to occur, then increases the level of load shedding from the battery each day until it reaches absorption charging. From this point on, the load shedding value will be adjusted so that the absorption recharge takes place ca every week. The voltage of the solar panels must exceed the battery voltage by at least 5 V for the controller to start working and charging the battery. The controller charges until the panel voltage is 1 V higher than the battery voltage. Remotely manage and monitor the extensive features of the BlueSolar MPPT controller by connecting the Bluetooth dongle and pairing it with a smartphone or other device via VictronConnect. When your device is connected to the Internet, the Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; both services are free to use. You can use the VICTRON CALLER to select a suitable controller.

Intelligent charging

If the BlueSolar controller is not able to fully charge the batteries in one day, the result is a gradual discharge of the battery, with each cycle further exacerbating this condition. Battery Life's intelligent charging algorithm monitors this condition, and if it begins to occur, then increases the level of load shedding from the battery each day until absorption charging is reached. From this point on, the load shedding value will continue to be adjusted so that the absorption recharge takes place approximately every week.
