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 provide optimal battery care and control for up to 900 Wp of 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 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.
