Steca Solarix PRS

Description

The Steca Solarix PRS solar charge controller offers impressive simplicity and performance while also boasting a modern design with a convenient display at an extremely attractive price.

Multiple LEDs in different colours provide information about the battery's state of charge at a glance. Modern Steca algorithms are used to ensure optimal battery maintenance. The Steca Solarix PRS charge controllers are equipped with an electronic fuse, offering ideal protection. They operate according to the serial principle and separate the solar module from the battery to protect against overcharging.

For larger projects, charge controllers can also be equipped with special functions, e.g. a night light function and selectable charge termination and deep discharge protection voltages.
