The Steca PR 20-20-charge controller series is the highlight of the solar charge controllers.
The latest charging technologies, combined with a significantly improved Steca-AtonIC state-of-charge determination result in optimum battery maintenance and control of the module output of up to 900 Wp which can be connected. A large display informs the user about all operating modes with the help of symbols. The state of charge is represented visually in the form of a tank display. Data such as voltage, current, and charge can also be displayed digitally as figures on the display. In addition, the controller has an energy meter that can be reset by the user.
