Victron SmartSolar MPPT 150/45 Solar Charge Controller

MPP Solar Charge Controller MPPT 150/45 by Victron.

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

Ultra-fast MPPT Tracking
Especially in cloudy 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. Advanced Maximum Power Point Detection in case of partial shading. In the event of partial shading, there may be two or more maximum power points (MPP) on the current-voltage curve. Conventional MPPTs tend to settle on a local MPP. However, this may not be the optimal MPP. The innovative algorithm of the BlueSolar device will always maximize energy yield by adjusting to the optimal MPP.

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

Intelligent 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, the load disconnect threshold is modulated so that the constant voltage is reached approximately once a week. The BatteryLife algorithm will extend the operating life of the battery compared to conventional battery algorithms, which 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 150 / 45 automatically adapts to a 12 V, 24 V or 48 V system.

Three-stage charging: Instead of simply charging at a constant rate up to the charging voltage, an innovative multi-stage system is used. (Constant current, constant voltage, and float phase.)
