Steca Solarix
Alpha, Gamma, Sigma, Omega
Steca’s Solarix series is the world’s most sold PV charge
controller for the use in medium sized solar home systems
and PV power supplies in the range of 8 to 30 A (up to
900 Wp). The heart of the controller is the integrated cir-
cuit called ATONIC
®
, which contains the regulation soft-
ware based on a self learning algorithm. The result is an
accurate state of charge (SOC) metering of the battery,
the best insurance for a long battery lifetime.

Steca Solarix PRS
The simplicity and high performance of the new Steca
Solarix PRS solar charge controller make it particularly at-
tractive. 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 charge status of the bat-
tery. Here, Steca’s latest algorithms are employed in order
to guarantee optimal battery maintenance. The Solarix
PRS charge controllers are equipped with an electronic fu-
se, 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, which means 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. These include the night
light function, selectable charging plateau and deep-
discharge protection voltages.
