Steca PR 

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.
