Steca Solarix PRS Solar Charge Controllers:

The simplicity and high performance of the Steca Solarix PRS solar charge controller make it particularly attractive. Here, Steca’s latest algorithms are employed in order to guarantee optimal battery maintenance. The Solarix PRS charge controllers are equipped with an electronic fuse, thus ensuring the optimal protection. They operate on the serial principle, and separate the solar module from the battery in order to protect it against overcharging. The Solarix PRS charge controllers are universal charge controllers: they can be used with lead-acid batteries or gel batteries without the need for complex configuration settings. For larger projects, the charge controllers can also be equipped with special functions: night light function, selectable charging plateau and deep discharge protection voltages. The Steca Solarix PRS works on PWM as a low loss series controller.
