The functionality of the Steca PR 2020 IP is based on the series of solar charge controllers Steca PR.

This series features a large display that shows the state of charge (SOC) Current in percentage and graphically in the form of a gauge tank. The centerpiece of the charge controller is a device for determining the state of charge which has been the subject of considerable optimization.

The status of self-adaptive charging algorithm allows optimal battery maintenance and control of a power panel connected up 480 Wc. The Steca PR 2020 IP has been specially designed for use in harsh environments with high salt content, moisture and dust.
