Pulse width modulated (PWM) charge controller turn on and off very rapidly, holding
the batteries at full charge, making better use of available power

This high class 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
