The Smartsolar 100/20-48 from Victron Energy (MPN SCC110020160R) is an MPPT solar charge controller with a maximum charging current of 20A for charging 12V, 24V and 48V batteries. Unlike the BlueSolar version, the Smart version has built-in Bluetooth, so you no longer need to buy a Bluetooth dongle. For communication with other Victron devices such as the Color Control GX or the MPPT Control, a VE.Direct port is still available as well.
The built-in Bluetooth in the SmartSolar series is the wireless way to set up, monitor and update the controller using Apple and Android smartphones, tablets or other devices. The optional MPPT WireBox-S 100-20 from Victron Energy is the ideal addition to your SmartSolar charge controller. It safely covers the cable entries and connection terminals of the controller and protects them from external influences and accidental contact.

Ultra-fast Maximum Power Point Tracking
Especially under overcast skies, when the light intensity changes constantly, an extremely fast MPPT controller increases the energy yield by up to 30 % compared with PWM charge controllers and by up to 10 % compared with slower MPPT controllers.
Intelligent 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 preset voltage. Alternatively, an intelligent battery management algorithm can be selected: see BatteryLife.
The load output is short-circuit proof.
Battery Life: intelligent battery management
If the solar charge controller is unable to fully charge the battery within one day, the battery status keeps switching back and forth between "partially charged" and "end of discharge". This operating mode (no regular full charge) 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 load disconnect threshold day by day (i.e. the load is disconnected earlier) until the energy harvested is sufficient to charge the battery to almost 100 %. From that point on, the load disconnect threshold is modulated so that charging to almost 100 % is achieved about once a week.

Note
The device is marked 48V – the data sheet of the 48V version is printed on the side of the packaging. Contrary to this confusing marking on the device itself, it is, as described, suitable for 12V and 24V – and by now also for 48V battery banks. Until recently these were separate devices – one for 12V/24V and one for 48V – which have now been merged, and the printing on the housing and packaging was taken over from the 48V version
