Victron SmartSolar MPPT 250/100-Tr VE.Can

This regulator charges all 12V, 24V and 48V batteries (including lithium) and can be adapted for use with the Victron Bluetooth app so you can monitor and adjust battery charging from your smartphone!
Using Bluetooth you can view information such as:

• Solar Gauge – Realtime power output
• Battery Voltage and State
• Load current being drawn by appliances
• Battery Charge History Analysis
• Various Settings

Using the VE Can port, up to 25 charge controllers can be daisy-chained and connected to a Color Control GX or other GX device. This greatly improves wiring simplicity and cost on large systems. Previously, all units required their own communications cable to be wired to a network of adapters and USB hubs to connect to the GX Device. The VE.Direct port found on other controllers is retained, ensuring no functionality is lost by selecting the VE.CAN 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. In the event of partial shading, the innovative BlueSolar algorithm will always maximize energy harvest by locking to the optimum MPP.

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, 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.

Other Features:

• IP43 rated charger casing and resin encapsulated electronics offers all vital components exceptional protection from the environment
• Programmable battery charge algorithm allows you to tailor the chargers output to your specific requirements
• Internal temperature sensor compensates absorption and float charge voltage for temperature to ensure optimal efficiency
• Fully discharged battery recovery function will initiate charging even if the battery has been discharged to zero volts
• Optional external battery voltage and temperature sensing via Bluetooth using a Smart Battery Sense or a BMV-712 Smart Battery Monitor
• Long 5 year manufacturer warranty for added confidence
