Steca PR 2020 IP


Available in 1 day, delivery time 2-5 days

Product number: 030401015
Product information "Steca PR 2020 IP"

Steca PR 2020 IP 65 Version

  • High End State of Charge control (SOC)
  • Professional battery care
  • Full grafical display
  • Automatic battery voltage detection
  • Full load protection

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

This is equipped with a a large display which shows the current state of charge (SOC) as a percentage and graphically in the form of a tank. State of charge recognition forms the core of the charge controller. The auto-adaptive state of charge algorithm results in optimal battery maintenance and control over the module output of up to 600 Wp which can be connected to it. The Steca PR 2020 IP has been specially designed for operation in difficult environments with high salt, moisture and dust content.

Accessory Items

Steca PA TS10
Steca PA TS10 The Steca PA TS10, Steca PA TSIP10 and Steca PA TS-S external temperature sensors are used for monitoring the battery temperature.All Steca solar charge controllers have an integrated temperature sensor that makes them capable of adjusting the charging strategy to suit the current temperature conditions. The external temperature sensors are only required when the battery must be installed in a different room to the solar charge controller.The Steca PA TS10 and Steca PA TSIP10 are supplied with a plug for connection to the solar charge controller and ring eyelets for connection to the battery screw.The external temperature sensors are suitable for use with Steca PR 10-30, Steca Solarix MPPT, Steca PR 2020 IP, Steca Tarom 4545 and Steca Tarom MPPT 6000 solar charge controllers.
