Once the battery reached the specified voltage range, pulse current charging mode allows the battery to react and allows for an acceptable rate of charge for the battery level. Sensed battery voltage and the specified voltage regulation set point. The duty cycle is proportional to the difference between the The charge controller uses automatic duty cycle conversion, creating pulses of current to charge the battery. For the most accurate return of capacity, and for the prevention of excessive gassing pressure, the battery is required to be controlled by specified voltage regulation set points for Absorption, Float, and Equalization charging stages. Battery charging is a current based process so controlling the current will control the battery voltage. The Wanderer utilizes Pulse Width Modulation (PWM) technology for battery charging. Charges over-discharged lithium batteries. Integrated communication port for remote monitoring.Remote temperature compensation compatible (accessory sold separately).Multiple LED indicators for easy to read charge status and battery information.Protection against: reverse current, overcharging, short-circuit and reverse polarity.Temperature compensation and correcting the charging and discharging parameters, automatically, improving battery life.Deep Cycle Sealed, Gel, Flooded, and Lithium battery options.equipped with fully omprehensive self-diagnostics and electronic protection functions to prevent damage from installation mistakes or system faults. Integrating highly efficient PWM charging, the Wanderer increases battery life and improves system performance. The Wanderer is an advanced charge controller for off-grid solar applications and can be used with a 12V battery or battery bank. NEVER connect solar panels to charge controller until the battery is connected. Warning: Connect battery terminals to the charge controller BEFORE connecting the solar panel(s) to the charge controller. Before using Wanderer to charge other types of lithium battery, set the parameters according to the suggestions from battery manufacturer. Default charging parameters in Li mode are programmed for 12.8V Lithium Iron Phosphate (LFP) Battery only.Do NOT equalize VRLA type AGM / GEL / LITHIUM batteries UNLESS permitted by battery manufacturer.Equalization is carried out only for non-sealed / vented / flooded / wet cell lead acid batteries.Please carefully review the specific requirements of the battery used in the system. Too high of an equalizing charge or too long of one may cause damage. Over-charging and excessive gas precipitation may damage the battery plates and activate material shedding on them.Wear eye protection and have fresh water available in case there is contact with the battery acid. Be careful when working with large lead acid batteries.Be certain there is enough ventilation to release the gases. Explosive battery gases may be present while charging.Use only sealed lead-acid, flooded, gel or lithium batteries which must be deep cycle.Do NOT let the positive (+) and negative (-) terminals of the battery touch each other.Do NOT allow water to enter the controller.The charge controller should be installed indoors in a well-ventilated, cool, and dry environment.Use the Open Circuit (Voc) to make sure the voltage does not exceed this value when connecting panels together in series. Ensure input voltage does not exceed 25 VDC to prevent permanent damage.This may cause a dangerous occurrence where the controller would experience a high open-circuit voltage at the terminals. NEVER connect the solar panel array to the controller without a battery.There may be sparks when making connections, therefore, make sure there are not flammable materials or gases near installation. Make sure all connections going into and from the controller are tight.Do NOT disassemble or attempt to repair the controller. There are no serviceable parts for this controller.Read all of the instructions and cautions in the manual before beginning the installation.Indicates a procedure or function that is important to the safe andproper operation of the controller Indicates a critical procedure for safe and proper operation of theController Use extreme cautionwhen performing this task Indicates a potentially dangerous condition. The following symbols are used throughout the manual: Warning This manual contains important safety, installation, and operating instructions for the charge controller.
