The simplicity and high performance of the new Steca Solarix PRS solar charge controller make it particularly attractive. Steca have used their latest algorithms to achieve optimal battery maintenance.

The Solarix PRS charge controllers are equipped with an electronic fuse, ensuring optimal protection. They operate on the serial principle, and separate the solar module from the battery to protect it against overcharging.

The Solarix PRS charge controllers are universal: they can be used with lead-acid batteries or gel batteries without the need for complex configuration settings. For larger projects, special functions can be added to the charge controllers: night light function, selectable charging plateau, and deep discharge protection voltages.
