Steca PR Night
PR 0606N, PR 1010N
The Steca PR Night is designed for operating automatic night
light systems and is suitable for solar systems of up to 300
Wp module output.
This controller is thus especially suitable for streetlights, bus
stops, advertising lighting and other similar applications. The
charge controller determines the actual solar time via the so-
lar module. This integrated clock can be used to define how
long after sunset, or before sunrise, the light is to be switched
on or off.

Steca PR
PR 1010, PR 1515, PR 2020, PR 3030
The Steca PR 10-30 series of charge controllers is the high-
light in the range.
The latest charging technologies, combined with a Steca-
AtonIC state of charge determination which has been signi-
ficantly improved once again, result in optimal battery main-
tenance and control of the module output of up to 900 Wp
which can be connected to it. A large display informs the
user about all operating modes with the aid of symbols. The
state of charge is represented visually in the form of a tank
display. Data such as voltage, current and state of charge can
also be displayed digitally as figures on the display. In addi-
tion, the controller has an energy meter which can be reset
by the user.
