PV voltage up to 150 V

The BlueSolar MPPT 150/70 charge controller will charge a lower nominal-voltage battery from a higher nominal voltage PV array. The MPPT Charge controller will automatically adjust to a 12, 24, 36, or 48V nominal battery voltage.

CAN bus 

To parallel up to 25 units, to connect to a ColorControl panel or to connect to a CAN bus network

Ultra-fast Maximum Power Point Tracking (MPPT)

In sudden shaded conditions or cloudy skies, 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. Many conventional MPPT’s tend to lock to a local MPP, this may not be the optimum MPP.

The innovative BlueSolar algorithm maximizes energy harvest by locking to the optimum MPP.

Outstanding conversion efficiency

Maximum efficiency exceeds 98%. Full output current at up to 40°C operating conditions (104°F).

Flexible charge algorithm

Several preconfigured algorithms. Manual or automatic equalization.

Battery temperature sensor and battery voltage sense option.

Programmable auxiliary relay for alarm or generator start purposes

Extensive electronic protection

Over-temperature protection and power derating when the temperature is high.

PV short circuit and PV reverse polarity protection. Reverse current protection.
