Recognised as a global manufacturing leader in off-grid solar electronics, we are proud to be a direct distributor of Steca Elektronik products. All Steca controllers are able to control the entire energy flow while ensuring optimal battery maintenance in any power system. With the development, production, and testing stages conducted in their German manufacturing facility and all products supported by a 5 year warranty, Steca products are truly "100% made in Germany" to the highest European quality standards.

This StecaTM 10A PWM charge controller uses the latest charging technologies, and is suitable for 12V or 24V battery banks. State of charge determination (using Steca AtonIC technology) enables optimal battery maintenance and module power monitoring.

The controller is designed to protect batteries whilst charging them, providing automatic cut off to prevent over-charging and deep discharge. It comes with an automatic electronic fuse and a full range of electronic protection functions: overload, short circuit, high voltage, reverse polarity, high temperature, lightning and transient surges, reverse current at night, and load disconnection.

Other key features of this controller include:

Extremely high reliability, with an integrated self-test function and a long 5 year warranty
Parallel connectivity, to allow two or more controllers for large solar arrays
Multistage PWM pulse charging increases your battery life
Automatic data logging and easy to use LCD display to show operating parameters
CE and RoHS compliant, designed and manufactured in Germany

This controller can work with sealed, AGM, gel and any liquid electrolyte batteries.
