Victron BlueSolar MPPT 100/20 charge controller (up to 48 V)

MPP solar charge controller MPPT 100/20 from Victron

A charge controller is the heart of every solar system and connects the solar panel to the battery. The solar controller uses high-performance technology to convert the voltage, which fluctuates throughout the day, into a voltage that is adapted to the load or optimized for ideal and gentle battery charging.

Ultra-fast MPPT tracking
Especially under overcast skies, when light intensity is constantly changing, 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 partial shading. In the case of partial shading, two or more maximum power points (MPP) may exist on the current-voltage curve. Conventional MPPTs tend to lock on to a local MPP, but this may not be the optimal MPP. The innovative algorithm of the BlueSolar device will always maximize energy yield by locking on to the optimal MPP.

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

Internal temperature sensor
Of course, a temperature measurement unit is built in, so that constant and float voltages are balanced according to temperature. The full output current can thus be guaranteed up to 40°C.

Automatic detection of battery voltage
The MPPT 100 / 20 automatically adapts to a 12 V, 24 V or 48 V system.

Three-stage charging : Instead of simply charging constantly up to the charging voltage, an innovative step system is used (constant current, constant voltage, and charge maintenance phase).
