Description
The Steca PR 10-30 charge controller series is the highlight among solar charge controllers. The latest charging technologies combined with a significantly improved Steca Aton IC-Charging status determination provide optimum battery maintenance and control of up to 900 Wp panel power, which can be connected. A large display informs the user with the help of symbols about all the operating states. The charging status is visually displayed in the form of a tank display. Data such as Voltage, current and charging can also digital as a number shown on the display. In addition, the controller via an energy counter, which the user self-resetting.
