Product description
Steca PR (IP65 series) charge controller with LCD display
The functionality of the Steca PR 2020 IP is based on the Steca PR solar charge controller series. This controller features a large display that shows the current state of charge (SOC) as a percentage and graphically as a fuel gauge.
The core of the charge controller is the significantly improved state of charge determination. The self-learning state of charge algorithm ensures optimal battery maintenance and control of the up to 480 Wp module output that can be connected. The Steca PR 2020 IP is specially designed for operation in challenging environments with high salt, moisture, and dust content.
