  • Victron BlueSolar MPPT 75/15 Solar Charge Controller 15A


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.

BatteryLife: intelligent battery management
When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will be continually be cycled between a “partially charged” state and the “end of discharge” state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months.

The BatteryLife algorithm will monitor the state of charge of the battery and day by day slightly increase the load disconnect level until absorption voltage is reached. From that point onwards the load disconnect level will be modulated so that absorption voltage is reached about once every week.

The MPPT 75/15 can also be set to follow the traditional load control mode with a fixed disconnect voltage

The load output is short circuit proof and can supply capacitive loads such as an inverter

Resin encapsulated electronics
Protects the electronic components against the environment

Automatic battery voltage recognition
The MPPT 75/15 will automatically adjust to a 12V or a 24V system.

1a) If more PV power is connected, the controller will limit input power to 200W resp. 400W
1b) PV voltage must exceed Vbat + 5V for the controller to start. Thereafter minimum PV voltage is Vbat + 1V
