Product information "Steca PR 2020"

Steca PR 2020

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

The Steca PR 10-30 series of charge controllers is the highlight in the range.

Use of the latest charging technologies combined with state of charge determination enable optimal battery maintenance and module power monitoring for up to 900 Wp of connected power. A large display informs the user about all operating modes with the aid of symbols. The state of charge is represented visually in the form of a tank display. Data such as voltage, current and state of charge can also be displayed digitally as figures on the display. In addition, the controller has an energy meter which can be reset by the user.

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.
