The STECA PR Solar Charge Controllers have been specially designed for operation in difficult environments with high salt, moisture and dust contents.

The PR 2020 IP is equipped with a large LCD display that shows the current state of charge (SOC) as a percentage and graphically in the form of a tank. This visual representation also provides operating parameters, failure messages and self-test.

The “auto-adaptive” state of charge algorithm results in optimal battery maintenance and control over the module output of up to 480 Wp, which can be connected to it.

Manufactured according to ISO 9001 and 14001, RoHS, European Standards and DIN IEC 68 part 2-30 (use in tropical areas).
