Victron Energy BlueSolar MPPT 150/70-MC4

A charge controller is the heart of every solar system and connects the solar panel to the battery. The voltage that changes over the course of the day is converted by the solar controller using high-performance technology into a voltage that is adapted to the loads or optimized for ideal and gentle battery charging.

Ultra-fast MPPT tracking

Especially under cloudy conditions when the light intensity is constantly changing, the super-fast MPPT algorithm improves energy harvest 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, 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 the energy yield by adjusting to the optimal MPP.

Highlight: Real-time display of data on the smartphone!

A Bluetooth-enabled smartphone can display a variety of data live. You can find more information and the dongle here in our shop

intelligent battery management with the BatteryLife algorithm

The BatteryLife algorithm monitors the state of charge of the battery and slightly increases the threshold value for switching off the load every day until the constant voltage is reached. From this point, the threshold for switching off the load is modulated so that the constant voltage is reached about once a week. The BatteryLife algorithm will increase the operational lifetime of the battery compared to traditional battery algorithms, which always switch between "partially charged" and "fully charged" (due to low self-discharge)

Internal temperature sensor

Of course, a temperature measuring unit is installed internally, so that constant and float voltages are compensated for by temperature. The full output current can be guaranteed up to 40°C.

Automatic battery voltage detection

The MPPT 100/70 will automatically adjust to a 12V,24V or 48V system.

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