The Steca PR charge controllers were launched in 2004 as
the fifth generation of charge controller technology (up
to 900 Wp). This state of the art product upgrades the
Steca Solarix series by a customer designed LCD which
shows the accurate state of charge (SOC) in percent and
as battery gauge symbol. The heart of the controller is
the integrated circuit called ATONIC®II, which contains
the improved regulation software based on a self learning
algorithm.

Steca PR 2020-IP
IP 65 Version
The PR 2020-IP design is based on Steca’s PR charge con-
troller series with a customer designed LCD which shows
the accurate state of charge (SOC) in percent and as bat-
tery gauge symbol. The heart of the controller is the in-
tegrated circuit called ATONIC® II, which contains the
improved regulation software based on a self learning
algorithm. The PR 2020-IP controller operates in harsh
environments like salt, moisture and dust.
