SOLAR CHARGE CONTROLLERS
Steca Solarix PRS
PRS 1010, PRS 1515, PRS 2020, PRS 3030
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.
