The simplicity and high performance of the Steca Solarix PRS solar charge controller make it particularly appealing. At the same time, it offers a modern design and a convenient display, all at an extremely attractive price.
Several LEDs in various colours emulate a tank display, which gives information on the battery‘s state of charge. Here, Steca’s latest al- gorithms are employed, resulting in optimal battery maintenance. The Solarix PRS charge controllers are equipped with an electronic fuse, thus making optimal protection possible. They operate on the serial principle, and separate the solar module from the battery in order to protect it against overcharging.
For larger projects, the charge controllers can also be equipped with special functions: e.g. with night light function and selec- table charging plateau and deep-discharge protection voltages.
