Description
Built-in Bluetooth Smart
The wireless solution for setting up, monitoring and updating the SmartSolar charge controller.
VE.Direct
For a wired data connection with a Color Control GX, other GX products, a PC or other devices.
Ultra-fast maximum power point tracking (MPPT)
Especially in cloudy weather, when the light intensity is constantly changing, an extremely fast MPPT controller improves the energy yield by up to 30 % compared to PWM charging controllers.
by up to 30 % compared to PWM charge controllers and by up to 10 % compared to slower MPPT controllers.
Load output
A 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 predefined voltage value.
(48 V model: interface to a relay) 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 one day, the status of the battery
constantly switches back and forth between "partially charged" and "end of discharge". This operating mode (no regular full charging) will damage a lead-acid battery within
lead-acid battery within a few weeks or months.
The BatteryLife algorithm monitors the state of charge of the battery and, if necessary, raises the threshold for disconnecting the load on a daily basis
(i.e. the load is disconnected earlier) until the energy gained is sufficient to charge the battery to almost 100%. From this point
the threshold for disconnecting the load is modulated so that charging to almost 100% is achieved approximately once a week.

Internal temperature sensor
Equalizes constant and charge retention voltages according to temperature.
Option external battery voltage and temperature measurement via Bluetooth
A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to transmit the battery voltage and temperature data to one or more SmartSolar charge controllers.
one or more SmartSolar charge controllers.
Recovery function for fully discharged batteries
Will initiate charging even if the battery has been discharged to zero volts.
Will reconnect to a fully discharged lithium-ion battery with internal disconnect function.
