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-AtonIC state-of-charge determination result in optimal battery care and control of up to 900 Wp module power that can be connected. A large display informs the user about all operating states using symbols. The charge level is visually represented like 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.
