Victron BlueSolar MPPT 75/15 Solar Charge Controller

Victron BlueSolar Charge Controller MPPT 75/15

A charge controller is the heart of every solar system, connecting the solar panel to the battery. The voltage, which changes throughout the day, is converted by the solar controller using powerful technology into a voltage adapted to the loads or optimized for ideal and gentle battery charging.

Ultra-fast MPPT tracking
Particularly in overcast conditions, when light intensity constantly changes, the super-fast MPPT algorithm improves energy yield by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.

Highlight: Real-time data display on your smartphone!
A Bluetooth-enabled smartphone can display a variety of data live. Further information and the dongle can be found here in our shop

Smart battery management with the BatteryLife algorithm
The BatteryLife algorithm monitors the battery's state of charge and slightly increases the load disconnect threshold daily until the constant voltage is reached. From this point on, the load disconnect threshold is modulated so that the constant voltage is reached approximately once a week. The BatteryLife algorithm will increase the operating life of the battery compared to conventional battery algorithms that always switch between "partially charged" and "fully charged" (due to low self-discharge)

Internal temperature sensor
An internal temperature measurement unit is, of course, built-in, so that constant and float charging voltages are temperature-compensated. The full output current can thus be guaranteed up to 40°C.

Automatic battery voltage detection
The MPPT 75 / 15 automatically adapts to a 12 V or 24 V system.

Three-stage charging: Instead of simply charging constantly up to the charging voltage, an innovative multi-stage system is used (constant current, constant voltage, and float charging phases).
