Steca PR
PR 1010, PR 1515 PR 2020, PR 3030
The Steca PR charge controllers were launched in the year 2004 as the fifth generation of charge controller technology (up to 900 Wp). This high class state of the art product upgrdes the Steca Solarix series by a customer designed LCD which shows the accurate state of charge (SOC) in percent nd as battery guage 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.
