STECA SOLARIX PRS
1010 | 1515 | 2020 | 3030
The Steca Solsum F-Line continues the huge success of one of the most
used SHS controllers. With a power range of up to 10 A at automatically
recognized 12 V or 24 V it fits to a system sizes of maximum 240 W.
Full circuit board protection with LED display for simple recognition of battery
status. Various connections make it possible to connect easily to solar
panels, battery and load. The Steca Solsum F works on PWM as a low loss
series controller.

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 give information on the battery‘s state of
charge. Here, Steca’s latest algorithms 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 selectable
charging plateau and deep-discharge protection voltages.
