BlueSolar Charge Controller MPPT 150/70 and 150/85

Solar Charge Controllers MPPT 150/70 and 150/85 PV Voltage up to 150 V

The BlueSolar MPPT 150/70 and 150/85 charge controllers will charge a lower nominal-voltage battery from a higher nominal voltage PV array. The controller will automatically adjust to a 12, 24, 36, or 48V nominal battery voltage.

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 BlueSolar algorithm will always maximise energy harvest by locking to the optimum MPP.

Outstanding Conversion Efficiency

No cooling fan. Maximum efficiency exceeds 98%. The full output current up to 40°C (104°F).

Flexible Charge Algorithm

• Several preconfigured algorithms.
• One user programmable algorithm
• Manual or automatic equalisation
• Battery temperature sensor. Battery voltage sense option

Extensive Electronic Protection

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

Programmable Auxiliary Relay

For alarm or generator start purposes.


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