The Steca PR 10-30 charge controller series is the highlight among solar charge controllers. The charging technologies, combined with a significantly improved Steca-AtonIC state of charge determination, provide optimal battery maintenance and monitoring of up to 900 Wp module power that can be connected. A large display informs the user about all operating states using symbols. The state of charge is visually represented in the style of a fuel gauge. Data such as voltage, current, and state of charge can also be displayed digitally as numbers on the screen. Additionally, the controller features an energy meter that the user can reset themselves.
