Victron MPPT 75/15 SmartSolar Charge Controller
Victron Energy Smart Solar MPPT 75/15 - (12/24V)
SmartSolar is all about functionality and options. These highly efficient ultra-fast Maximum Power Point Tracking (MPPT) solar charge controllers have it all - from high efficiency, optimal partial shading performance, programmable battery algorithms, street light functions and more.
Smart is for built in Bluetooth for monitoring and control with Victron Connect. Options include remote monitoring over the internet via the VRM Portal, also a pluggable LCD display for the larger models.

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.
Load output
Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage. Alternatively, an intelligent battery management algorithm can be chosen: see Battery Life.
Battery Life: 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 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 Battery Life algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%. From that point onwards the load disconnect level will be modulated so that a nearly 100% recharge is achieved about once every week.
