Solarix SIGMA Charge Controller

SunWize-Steca newest, and fourth, generation of solar charge controllers sets new standards in solar technology. For the first time a solar charge controller is offered in the market which is equipped with an integrated circuit ( ASIC ) specially designed for solar charging. This integrated circuit, called Atonic , provides a charge controller with new functions. Atonic is more than a protective device for your battery, and contains the most recent and innovative technology. It contains a self-learning algorithm which gives detailed information on the battery’s state of charge ( SOC ). It adjusts itself to the battery’s age and capacity. The SOC provides a basis for all control and regulatory functions. This new type of hybrid regulator is much more efficient than conventional series and shunt regulators. The newly introduced displays give information about the SOC, and faults. A combination of electronic and electro-mechanical protection increase the safety of the charge controller.

At the same time Prices for Solarix Charge Controllers are lower than before!

Overcharge Protection:
• Temperature-adjusted SOC and final voltage
• Optimised fast, medium and trickle charging
• The varied charging rate provide complete use of the battery capacity, and maximum life
• The controller adapts itself to 12V or 24V systems automatically on installation

Options:
• 6 character LCD Display
• Long term data collection PC interface
• External temperature sensor

Overdischarge Protection:
• The SOC provides load disconnect
• Warning of imminent load disconnect

Displays:
• Two LEDs, fixed/flashing, different colours, provide
SOC with 10 different colours and warning of load disconnect
Operation status and faults

Safety Features:
• Protection from overcurrent, overvoltage and overtemperaturer
• Protection from wrong polarity and short circuit
• Electronic overcurrent protection avoids blowing the fuse except in case of wrong polarity
• Extremly low electromagnetic emission
