Safety Information

Always observe the following safety precautions during installation and operation of the solar kit:

• Read all instructions in this manual before beginning installation.
• Do not disassemble or attempt to repair any components of the solar kit.
• Ensure all wiring is correctly polarized and securely connected to prevent electrical hazards.
• Wear appropriate personal protective equipment (PPE), including gloves and eye protection, during installation.
• Avoid touching live electrical connections.
• Disconnect all power sources before performing any maintenance or troubleshooting.
• Install the solar panels and charge controller in well-ventilated areas, away from flammable materials.
• Ensure the battery bank is properly sized and compatible with the charge controller.
• Do not expose the charge controller to water or excessive humidity.

Setup and Installation

Follow these steps for a proper 12V solar system setup. An inverter and battery are not included in this kit and must be acquired separately.

Installation Steps:

1. Step 1: Connect Solar Panels to a 12V (4P) Array. Connect the four 100W solar panels in parallel to form a 12V array. Use appropriate Solar Y Branch connectors for this configuration. Ensure all connections are secure and weatherproof.
2. Step 2: Set Up a 12V Battery Bank. Install your 12V battery bank (not included). Ensure the battery bank is properly charged and maintained according to its manufacturer's instructions.
3. Step 3: Link the Charge Controller to the Battery Bank. Connect the 30A Wanderer PWM Charge Controller to your 12V battery bank. Ensure the battery connections are made first to the charge controller before connecting the solar panels.
4. Step 4: Plug the Solar Panel Array Output into the Controller's PV Port. Connect the output from your solar panel array to the PV input terminals on the charge controller. The controller's terminals are compatible with solar cables up to 8 AWG. Ensure proper spacing and use pre-stripped cables for easy and quick connection.

Operating Instructions

Once the solar kit is installed, the 30A Wanderer PWM Charge Controller will automatically manage the charging process of your battery bank.

4-Stage Charging Process:

The charge controller employs a 4-stage charging algorithm to ensure efficient and safe battery charging, extending battery life:

• Bulk Charge: This initial stage delivers the maximum current to rapidly charge the battery.
• Boost Charge: Once the battery reaches a set voltage, the controller enters the absorption stage, maintaining a constant voltage to prevent overcharging and gassing. The default time for this stage is 120 minutes.
• Float Charge: After the boost charge, the voltage is reduced to a lower level to maintain the battery at full charge without overcharging.
• Equalization: This stage is an intentional overcharging for a controlled period, typically every 28 days. It helps to balance battery cell voltages and prevent sulfation, particularly beneficial for certain types of lead-acid batteries. During equalization, it is recommended to have no load on the batteries.

Monitoring and Adjustment (Optional):

• Bluetooth Module (BT-1): An optional BT-1 Bluetooth Module (not included) can be connected to the charge controller for real-time monitoring of system performance via the Renogy DC Home app. This allows for voltage tracking and tailoring of Boost Charge Voltage for Li batteries (from 12.6V to 16V).
• Temperature Sensor: An optional temperature sensor (not included) can be added to the charge controller to adjust charging voltage based on battery temperature, optimizing performance and extending the lifespan of lead-acid batteries.

Maintenance

Regular maintenance ensures optimal performance and longevity of your solar power system.

• Solar Panels: Periodically clean the surface of the solar panels with a soft cloth and mild, non-abrasive cleaner to remove dirt, dust, and debris. Ensure panels are dry before reconnecting to the system if disconnected for cleaning.
• Connections: Regularly inspect all electrical connections for tightness and corrosion. Loose or corroded connections can lead to power loss or safety hazards.
• Charge Controller: Keep the charge controller free from dust and ensure adequate ventilation around the unit.
• Battery Bank: Follow the battery manufacturer's maintenance guidelines for your specific battery type. This may include checking electrolyte levels for flooded lead-acid batteries or monitoring voltage for sealed batteries.

Troubleshooting

This section addresses common issues you might encounter with your Renogy solar kit.

Common Issues and Solutions:

• No Power Output from Solar Panels:
  • Check for shading on the solar panels.
  • Verify all connections from the panels to the charge controller are secure and correctly wired.
  • Ensure there is sufficient sunlight.
• Battery Not Charging or Charging Slowly:
  • Confirm the charge controller is correctly connected to both the solar panels and the battery.
  • Check battery voltage; if it's too low, the controller might not initiate charging.
  • Inspect for any loose or corroded battery terminals.
  • Ensure the battery type setting on the charge controller matches your battery.
• Charge Controller Displaying Warnings:
  • Over-Voltage Warning: Indicates the input voltage from the solar panels or battery voltage is too high. Check panel configuration or battery health.
  • Under-Voltage Warning: Indicates battery voltage is too low. Charge the battery or check for excessive load.
  • Over-Discharge Warning: Indicates the battery has been discharged too deeply. Reduce load or increase charging capacity.
• Equalization Mode Concerns:
  • The equalization process is an intentional overcharge. It is crucial to ensure there is no load on the batteries when this stage is active to prevent damage to connected appliances or the battery itself.
  • If charging current falls during equalization, the device may pause this mode and resume when adequate charging current is available.
