Control and Protect your Battery from Overcharges and Deep-Discharges


The iSCC-XN™ Series of XUNZEL are sophisticated solar charge and discharge controllers for small solar systems where, charge and discharge control are required. They are equipped with a microprocessor and provide high efficiency displaying the normal operation, alarm messages, etc. in a simple way with acoustic signals and display.


The solar charge and discharge controllers iSCC-XN™ of XUNZEL are programmable and provided with negative grounding. In addition to a perfect PWM regulation with integrated temperature compensation, the controllers provide fully electronic safety functions.


Their multi-stage (4-stage) PWM charging method (Float – Main – Boost – Equalization) is adjustable for different types of batteries: GEL/AGM or Flooded (Factory setting).


These solar charge and discharge controllers also come with three deep discharge functions: Low Voltage Warning (LVW), Low Voltage Disconnect (LVD) adjustable by State of Charge (SOC) or battery voltage (up to 5 different modes), and automatic Low Voltage Recovery (LVR).

The iSCC-XN™ Series of XUNZEL are equipped with multifunctional LCD in order to display clearly the charge status, the discharge status or the state of charge of the battery with a bar graph and the loads status. Furthermore, these controllers are one of few controllers in their class that have an acoustic alarm before low voltage disconnection.


Thanks to their DC load output, there is no need of any inverter to power DC loads such as ultra-efficient low-voltage 12VDC or 24VDC LED NATURE Series lamps of XUNZEL. Consequently, savings and efficiency of the solar system are increased considerably.


These solar charge and discharge controllers are equipped with a wide range of programmable functions, such as LVD function, Nightlight function and Lock-out function. Moreover, their programming menu can configure iSCC-XN™ Series: battery type, LVD, Nightlight function (type, evening setting and morning setting), Day/Night threshold, Buzzer on/off, Serial Interface Functions and Individual/Factory settings.
