Victron Smartsolar MPPT 100/20 20A 12V 24 solar charger

The Smartsolar 100/20-48 from Victron Energy (mpn scc110020160r) is a mppt solar charge controller with 20a max charge current for charging 12v and 24v batteries. Unlike the Bluesolar version, the Smart version has integrated Bluetooth, which eliminates the need to purchase a Bluetooth dongel. In addition, a VE.Direct connection is still available for communication with other Victron devices such as the Color Control gx or the mppt Control.

The integrated Bluetooth in the SmartSolar series is the wireless solution to setup, monitor and update the controller using Apple and Android smartphones, tablets or other devices.

Ultra fast maximum power point tracking

Especially in overcast conditions when light intensity is constantly changing, an ultra-fast mppt controller improves power output by up to 30% compared to PWM charge controllers and by up to 10% compared to 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 value. Alternatively, an algorithm for intelligent battery management can be selected: see BatteryLife.
The load output is short-circuit proof.

Battery Life: intelligent battery management

If the solar charge controller is not able to charge the battery to its full capacity within a day, the status of the battery will constantly alternate between "partially charged" and "end of discharge". This mode of operation (no regular full charging) will damage 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., disconnects the load earlier) until the energy gained is sufficient to charge the battery to near 100%. From this point, the load disconnection threshold is modulated so that charging to near 100% is achieved about once a week.

Note

The device shows the imprint 48v - on the packaging of the device the data sheet of the 48v version is printed on the side. Contrary to this confusing information on the device itself, this is as described for both 12v and 24v - and now also suitable for 48v battery banks. Until recently these were separate devices - one for 12v/24v and one for 48v - these two have now been combined and the printing on the case and packaging has been taken from the 48v version
