Victron BlueSolar MPPT 75 Features:

 Ultra-fast Maximum Power Point Tracking (MPPT)

Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve 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 case of partial shading conditions

If partial shading occurs, two or more maximum power points may be present on the power-voltage curve.

Conventional MPPTs tend to lock to a local MPP, which may not be the optimum MPP. The innovative SmartSolar algorithm will always maximize energy harvest by locking to the optimum MPPT.

 

Outstanding conversion efficiency

No cooling fan.

Maximum efficiency exceeds 99%.

 

PV voltage up to 75V

The charge controller is

able to charge a lower nominal-voltage battery from a higher nominal voltage PV array. The controller will automatically adjust to a 12, or 24v nominal battery voltage.

 

Flexible charge algorithm

Fully programmable charge algorithm (see the software page on our website), and eight pre-programmed algorithms, selectable with a rotary switch (see manual for details).

 

Extensive electronic protection

Over-temperature protection and power derating when temperature is high. PV short circuit and PV reverse polarity protection. PV reverse current protection.

 

Internal temperature sensor

Compensates absorption and float charge voltage for temperature.

Adaptive three step charging
