Victron Energy SmartSolar MPPT 75/15
$67.15
A solar charger gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, SmartSolar maximizes this energy-harvest, driving it intelligently to achieve full charge in the shortest possible time. SmartSolar maintains battery health, extending its life. The SmartSolar charge controller will even recharge a severely depleted battery. It can operate with a battery voltage as low as 0 Volts, provided the cells are not permanently sulfated or otherwise damaged.
Description
MPPT: Ultra Fast Maximum Power Point Tracking
By constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing.
Remote Monitoring and Control
Remotely control and monitor the extensive features of your SmartSolar MPPT charger with built-in Bluetooth by pairing it with your smartphone or other device via VictronConnect. If your installation is connected to the internet with a GX device, the Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; both VictronConnect and VRM are free to use. For remote installations – even when there is no internet connection nearby – you may be able to monitor your MPPT by connecting the GlobalLink 520.
Load Output
The intelligent Load output function prevents damage caused by running batteries ‘flat’. You can configure the voltage at which SmartSolar disconnects a load – thereby preventing excessive drain on your batteries. And here’s the clever bit: SmartSolar will attempt a 100% recharge every day. If it can’t – during periods of poor weather – it raises the disconnect voltage, daily, until it achieves success. We call this feature BatteryLife because it maintains the health, and extends the life of your battery.

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 (48 V model: interface with a relay). Alternatively, an intelligent battery management algorithm can be chosen: see Battery Life. The load output is short circuit proof.
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.
Optional External Battery Voltage and Temperature Sensing via Bluetooth
A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature to one or
more SmartSolar Charge Controllers.
Fully Discharged Battery Recovery Function
Will initiate charging even if the battery has been discharged to zero volts. Will reconnect to a fully discharged Li-ion battery with integrated disconnect function.
Programmable Battery Charge Algorithm – Match your battery manufacturers specific charging specification requirements
Day/Night Timing and Light Dimming Option – Programable via the VictronConnect app.
Internal Temperature Sensor – Compensates absorption and float charge voltage for temperature.
