Steca PR 2020 IP

Description

The functionality of the Steca PR 2020 IP is based on the Steca PR solar charge controller series. It is equipped with a large display that visually shows the current state of charge (SOC) as a percentage and as a level meter. The core of the charge controller is the state of charge determination. The self-learning state of charge algorithm results in optimal battery care and control. The Steca PR 2020 IP is specially designed for operation in difficult environments with high levels of salt, moisture and dust.
