General Information The Wanderer is an advanced charge controller for off-grid solar applications. Integrating highly efficient PWM charging, this controller increases battery life and improved system performance. It is exclusively designed for 12V battery banks. The controller is embedded with self-diagnostics and electronic protection functions that prevent damages from installation mistakes or system faults.

Bulk Charge: This algorithm is used for day to day charging. It uses 100% of available solar power to recharge the battery and is equivalent to constant current. 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.
Optional Components *The Wanderer is shipped with by itself with no additional components. Optional components that require a separate purchase: Remote Temperature Sensor (TS-R): Measures the temperature at the battery and uses this data for very accurate temperature compensation. The sensor is supplied with a 6.6ft cable length that connects to the charge controller.
Key Parts 1. Battery Select Button 2. Battery Select Indicator 3. Battery Indicator 4. PV Indicator 5. Remote Temperature Sensor Adapter (Requires separate purchase) 6. PV Terminals 7. Battery Terminals Installation WARNING: Connect battery terminal wires to the charge controller FIRST then connect the solar panel(s) to the charge controller.
3. Insert temperature sensor block terminal and connect wires (POLARITY SENSITIVITY DOES NOT MATTER) Operation After connecting the battery to the charge controller, the controller will turn on automatically. Operation of this controller is very simply. Users set the battery type, and leave the rest of the work to the charge controller.
coded) and simply leave the controller alone until the flashing stops (this should take approximately 10 seconds). This indicates the parameter has been set. NOTE: If the LED lights do not flash, hold the gray button for 7 seconds again, release, and immediately press the gray button again to enable the flashing Set Battery Type Sealed...
System Status Troubleshooting Description Troubleshoot Use a multi-meter to verify the rated battery voltage. Disconnect any loads connected to the battery to allow it to Battery is low-voltage charge. Use a multi-meter to check the voltage of the battery. Make sure the battery voltage is not exceeding the rated Battery is over-voltage specification of the charge controller.
Maintenance For best controller performance, it is recommended that these tasks be performed from time to time. 1. Check that controller is mounted in a clean, dry, and ventilated area. 2. Check wiring going into the charge controller and make sure there is no wire damage or wear.
