Wiring Sequence:
Follow this sequence carefully to prevent damage to the controller or other components:
- Connect the Battery: Connect the positive (+) and negative (-) battery cables to the BATT terminals on the charge controller. Ensure correct polarity. The controller will power on.
- Connect the Solar Panel: Connect the positive (+) and negative (-) solar panel cables to the PV terminals on the charge controller. Ensure correct polarity.
- Connect the Load (Optional): If using the load terminals, connect your DC load to the LOAD terminals. (Note: This model does not feature dedicated load terminals for direct connection, but rather manages battery charging for external loads connected directly to the battery.)
- Connect Temperature Sensor (Optional): Plug the temperature sensor into the Temp. Sensor port. This allows for accurate temperature compensation.
- Connect Bluetooth Module (Optional): Plug the BT-1 Bluetooth module into the RS232 port for wireless monitoring via the Renogy DC Home App.
6. Operating Instructions
LED Indicators:
The LED indicators on the controller provide visual feedback on the charging status and selected battery type:
- PV LED: Indicates solar panel activity.
- BATT LED: Indicates battery charging status and battery type.
Battery Type Selection:
The controller automatically detects 12V systems. To select the battery type, press the button on the controller. The BATT LED will change color to indicate the selected battery type:
- Green: Sealed Battery
- Orange: GEL Battery
- Red: Flooded Battery
- Blue: Lithium (LiFePO4) Battery

4-Stage PWM Charging:
The controller employs an intelligent 4-stage charging algorithm to maximize battery lifespan and performance:

- Bulk Charge: Rapidly charges the battery to approximately 80% capacity.
- Boost Charge: Continues charging at a higher voltage to ensure full charge absorption.
- Float Charge: Maintains the battery at a full charge by providing a small, constant current.
- Equalization Charge: (For Flooded batteries only) Periodically overcharges the battery to balance cell voltages and prevent sulfation.
Lithium Battery Activation:
The Wanderer Li 30A can activate dormant lithium batteries by sending a low current to trigger the Battery Management System (BMS).

7. Advanced Features
Accurate Temperature Compensation:
When the optional temperature sensor is connected, the controller precisely measures battery temperature and adjusts charging parameters automatically. This extends battery lifespan by preventing undercharge in cold conditions and overcharge in hot conditions.

Wireless Monitoring (with BT-1 Module):
For enhanced control and monitoring, connect the optional Renogy BT-1 Bluetooth module to the RS232 port. This allows you to wirelessly monitor your solar system's performance, including solar input, battery State of Charge (SOC), and fault alerts, directly from your smartphone via the Renogy DC Home App.
