Steca PR2020 solar charge controller 12/24V 20A with LCD
The Steca PR series solar regulators are a complete system control and monitoring product designed for use on small to medium solar power systems. An easy to read LCD screen shows an accurate state of charge (SOC) in percent and as battery gauge symbol (provide all load is run through the load terminal). The heart of the controller is the integrated circuit called ATONIC II, which contains the regulation software based on a self-learning algorithm.
