Solar Controller Steca Solarix 4040

The Solar charge controllers Steca Solarix 4040 is a version Improved from the successful family of regulators Steca PR. Thanks to the highest module and load current, regulators are now also suitable for larger installations. They also have the equipment of a USB charging connector, in which smartphones and tablets can be loaded.

Steca Solarix 4040

  • High quality load State algorithm
  • Professional Battery Charging strategy
  • Graphic Display
  • Automatic Battery voltage detection
  • Professional load Monitoring

With the Steca Solarix 4040  You will enjoy the most modern charging technologies coupled with the determination of the state of charge form the perfect unit for the care and control of the battery.

Using symbols, a large display informs the user about operating states. The state of charge is represented visually as if of level indicators are treated. Data such as voltage, current and state of charge can also be displayed on the display with digital numbers. In addition, the controller has an energy meter that the user can reset.
