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 series of solar charge controllers. It features a large display that shows the current state of charge (SOC) as a percentage and graphically in the form of a fuel gauge.
The core feature of the charge controller is the significantly improved state-of-charge determination. The self-learning state-of-charge algorithm ensures optimal battery care and control of the connected module power of up to 480 Wp. The Steca PR 2020 IP is specially designed for operation in harsh environments with high salt, moisture, and dust content.
