![]() The protection circuit of lithium battery will typically turn the battery off and make it unusable if over-discharged. Lithium Battery Activation The Wanderer PWM charge controller has a reactivation feature to awaken a sleeping lithium battery. Boost Charge: When the battery has charged to the Boost voltage set-point, it undergoes an absorption stage which is equivalent to constant voltage regulation to prevent heating and excessive gassing in the battery. It uses 100% of available solar power to recharge the battery and is equivalent to constant current. VOLTAGE NIGHT BULK CHARGE BOOST FLOAT NIGHT TIME Bulk Charge: This algorithm is used for day to day charging. Key Features Optimized for 12 VDC system voltage 30A charging capacity. The controller comes equipped with fully comprehensive 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. General Information The Wanderer is an advanced charge controller for off-grid solar applications and can be used with a 12V battery or battery bank.

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. The following symbols are used throughout the manual: WARNING CAUTION NOTE Indicates a potentially dangerous condition.īattery Safety Do NOT let the positive (+) and negative (-) terminals of the battery touch each other. This manual contains important safety, installation, and operating instructions for the charge controller. Before using Wanderer to charge other types of lithium battery, set the parameters according to the suggestions from battery manufacturer.Important Safety Instructions Please save these instructions. ![]() Default charging parameters in Li mode are programmed for 12.8V Lithium Iron Phosphate (LFP) Battery only.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.Equalization is carried out only for non-sealed / vented / flooded / wet cell lead acid batteries.Do NOT equalize VRLA type AGM / GEL / LITHIUM batteries UNLESS permitted by battery manufacturer.Be certain there is enough ventilation to release the gases.Explosive battery gases may be present while charging.Do NOT let the positive (+) and negative (-) terminals of the battery touch each other.Tighten all terminals and inspect any loose, broken, or burnt up connections.Check wiring going into the charge controller and make sure there is no wire damage or wear.Check that controller is mounted in a clean, dry, and ventilated area.Do NOT allow water to enter the controller.įor best controller performance, it is recommended that these tasks be performed from time to time.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.User manual Energy Controllers Renogy CHARGE CONTROLLER Renogy CHARGE CONTROLLER Wanderer Li 30A 12V PWM Negative Ground Compatible - Use Manual - Use Guide PDF.
