Steca PR
Description
The Steca PR 10-30 charge controller series stands out among solar charge controllers. 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.
