Smart Battery Sense is a wireless battery voltage and temperature sensor for Victron MPPT solar chargers.
With a voltage and temperature sensor, the batteries are charged better, the charging capacity is improved and the battery life is extended.
Charging the battery is improved
Measurement of the voltage directly on the battery bank terminals avoids errors due to voltage flow due to cable resistance. This ensures the correct charging voltage.
For lead batteries, the battery temperature data is used to adjust the charge voltage: cold batteries require a higher charging voltage, while hot batteries require a lower charge voltage. For lithium batteries, the temperature data is used to interrupt the charging when the batteries are too cold: Charging lithium batteries at temperatures around or during freezing permanently damages the cells
