These solar charge controllers have a Bluetooth function included to monitor the working status of the controller and its whole system. The BT-1 and BT-2 Bluetooth adapter is used to extend Bluetooth communication function of the Bluetooth module. Mobile phone app can be used for wireless monitoring, parameters setting, and data view.

digital power technology, with circuit energy conversion efficiency as high as
charging mode. When the power of a solar panel is too large, and the charging
current is greater than rated current, the solar charge controller
automatically reduces charging power, thereby making the solar panel work at
rated charging current.

mechanism for over-temperature protection. When the temperature exceeds the
preset value, the charging current falls linearly with temperature, therefore
slowing down the rise of controller temperature and avoiding controller damage
from high temperatures.
