Victron SmartSolar MPPT 100/50 12/24V 50A Charge Controller with Bluetooth UF21679M

Victron Energy SmartSolar MPPT 100/50 12/24V 50A Solar Charge Controller

A solar charger gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, SmartSolar maximises 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 sulphated or otherwise damaged.
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.
Bluetooth Smart built-in
The wireless solution to set-up, monitor, update and synchronise SmartSolar Charge Controllers.
VE.Direct
For a wired data connection to a Color Control GX, other GX products, PC or other devices.
Ultrafast 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 maximize 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
Fully programmable charge algorithm (see the software page on our website), and eight pre-programmed algorithms, selectable with a rotary switch (see manual for details).
Extensive electronic protection
Over-temperature protection and power derating when temperature is high. PV short circuit and PV reverse polarity protection.
PV reverse current protection.
Internal temperature sensor
Compensates absorption and float charge voltage for temperature.
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.
