The Steca PR 1010-3030 series of charge controllers are top of the range, small solar charge controllers.
The latest charging technologies, combined with a Steca-AtonIC state of charge determination result in optimal battery chaging, maintenance and control of the solar panel outputs. A large, clear LCD display shows operating status and values using icons. The state of charge is represented visually in the format of fuel guage.
Information about the voltage, current and state of charge can also be displayed digitally as figures. The controller also has an energy meter which can be reset by the user.
