The Smartsolar 75/15 from Victron Energy is an MPPT solar charge controller with 15A max. charge current for charging 12V and 24V batteries. In contrast to the Bluesolar 75/15, the Smart version has integrated Bluetooth, which makes buying a Bluetooth dongle unnecessary. In addition, a VE.Direct connection is still available for communication with other Victron devices such as the Color Control GX or the MPPT Control.
The integrated Bluetooth in the SmartSolar series is the wireless solution for setting up, monitoring and updating the controller using Apple and Android smartphones, tablets or other devices. Optionally, the MPPT WireBox-S 75-10/15 from Victron Energy is the ideal addition for your SmartSolar charge controller. It safely covers the cable entries or connection terminals of the controller and thus protects them from external influences and contact.

Ultra-fast Maximum Power Point Tracking
Especially under overcast skies, when the light intensity is constantly changing, an extremely fast MPPT controller improves the energy yield by up to 30% compared with PWM charge controllers and by up to 10% compared with slower MPPT controllers.
Smart load output
Deep discharge of the battery can be prevented by connecting all loads to the load output. The load output disconnects the loads when the battery has been discharged to a specified voltage value. Alternatively, an algorithm for smart battery management can also be selected: see BatteryLife.
The load output is short-circuit proof.
Battery Life: smart battery management
If the solar charge controller is not able to charge the battery to its full capacity within a day, the battery's status constantly switches back and forth between "partially charged" and "end of discharge". This operating mode (no regular full charging) damages a lead-acid battery within a few weeks or months.
The Battery Life algorithm monitors the battery's state of charge and, if necessary, raises the threshold for disconnecting the load day by day (i.e. the load is disconnected earlier) until the energy gained is sufficient to charge the battery to almost 100%. From this point on, the threshold for switching off the load is modulated so that charging to almost 100% is achieved about once a week.
