The functionality of the Steca PR 2020 IP is based on the Steca PR line of solar charge controllers. This is equipped with a a large display which shows the current state of charge (SOC) as a percentage and visually as a level meter. State of charge recognition forms the core of the charge controller. The auto-adaptive state of charge algorithm results in optimal battery maintenance and control. The Steca PR 2020 IP has been specially designed for operation in difficult environments with high salt, moisture and dust content.
