Victron BlueSolar MPPT 150/70-Tr

MPP solar charge controller MPPT 150/70-Tr from 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 using high-performance technology into a voltage that is adapted to the load or optimized for ideal and gentle battery charging.

Ultra-fast MPPT tracking
Especially in overcast conditions, when light intensity is constantly changing, the super-fast MPPT algorithm improves energy yield by up to 30% compared to PWM charge controllers and 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 lock onto a local MPP. However, this may not be the optimal MPP. The innovative algorithm of the BlueSolar device will always maximize energy yield by locking onto the optimal MPP.

Highlight: Display of data in real time on your smartphone!
A Bluetooth-enabled smartphone can display a variety of data live

Intelligent battery management with the BatteryLife algorithm
The BatteryLife algorithm monitors the battery's state of charge and slightly increases the load disconnection threshold every day 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 increase the battery's operating life compared to traditional battery algorithms that always alternate 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 balanced according to temperature. The full output current can thus be guaranteed up to 40°C.

Automatic detection of battery voltage
The MPPT 150 / 70 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 stage system is used. (Constant current, constant voltage and charge maintenance phase.)
