Steca Solarix
Description
The Steca Solarix 2525 and 4040 solar charge controllers are a further development of the globally popular Steca PR controller family. Thanks to the increased module and load current, the controllers are now also suitable for even larger systems. The units also have an integrated USB charging socket that can be used to charge smartphones and tablets.
The latest charging technologies combined with a state of charge determination result in optimal battery care and control. A large display uses symbols to inform users about all of the operating states. The state of charge is displayed visually as a level meter. Data such as voltage, current and state of charge can also be shown digitally as a number on the display. The controller also has an energy counter that users can reset themselves.
