Steca PR 2020

High End State of Charge control (SOC)
Professional battery care
Full grafical display
Automatic battery voltage detection
Full load protection

The Steca PR 10-30 series of charge controllers is the highlight in the range.

Use of the latest charging technologies combined with state of charge determination enable optimal battery maintenance and module power monitoring for up to 900 Wp of connected power. A large display informs the user about all operating modes with the aid of symbols. The state of charge is represented visually in the form of a tank display. Data such as voltage, current and state of charge can also be displayed digitally as figures on the display. In addition, the controller has an energy meter which can be reset by the user.
