Steca Solarix 4040 Charge Controller | 12/24 Vdc | 40A | LCD

The Steca Solarix Series (2525 and 4040) represents the advanced evolution of the well-known Steca PR family, now optimized for larger solar installations with higher current requirements. These professional charge controllers feature a large digital display that provides real-time data on voltage, current, and battery state of charge (SoC) through intuitive symbols. Additionally, they incorporate a modern USB charging port for mobile devices, combining high-performance battery management with everyday practical utility.

The system uses the sophisticated Steca-AtonIC algorithm for precise state-of-charge determination and includes an integrated energy logger that allows users to track their solar production and consumption accurately.
