Sunway Solar Panel Combiner 3 to 1 Extension Wire Instruction Manual

1. Product Overview

The Sunway Solar Panel Combiner 3 to 1 Extension Wire with SAE Adapters is designed to connect up to three individual solar panels to a single 12-volt battery charger or maintainer. This allows for increased power input to a single battery system, optimizing charging efficiency. It is compatible with various solar battery trickle chargers and maintainers, including Suner Power, Powoxi, SOLPERK, OYMSAE, Eco-worthy, Battery Tender, Sunforce, and Renogy.

• Function: Combines output from three solar panels into one SAE connection.
• System Compatibility: Designed for 12-volt DC systems.
• Cable Gauge: 18 AWG.
• Maximum Panel Output: Each connected solar panel should have a maximum output power of 30W and a voltage of 15-18V.
• Important Note: This adapter is for connecting multiple panels to one battery, not one panel to multiple batteries.

2. Setup and Connection

Proper connection is crucial for safe and efficient operation. Always ensure correct polarity before making final connections.

2.1 Polarity Verification

Different brands of solar panels or battery chargers may have varying polarity configurations. It is essential to verify the polarity of your solar panel connectors before connecting them to the combiner cable.

• Normally, the positive (+) terminal is indicated by a red cable and the negative (-) by a black cable. However, this can vary.
• Use a voltmeter to confirm the positive and negative terminals of each solar panel's SAE connector.
• Ensure the combiner cable's SAE inputs match the polarity of your solar panels.

2.2 Connection Steps

1. Prepare Solar Panels: Ensure each solar panel is positioned to receive adequate sunlight. Verify that each panel's output does not exceed 30W and its voltage is within 15-18V.
2. Connect Panels to Combiner: Connect the SAE output connectors from up to three solar panels to the three input SAE connectors of the Sunway Solar Panel Combiner. Ensure a secure fit for each connection.
3. Connect Combiner to Charger/Maintainer: Connect the single output SAE connector of the combiner cable to the input SAE connector of your 12V battery charger or maintainer.
4. Connect Charger/Maintainer to Battery: Follow the instructions for your specific battery charger/maintainer to connect it to your 12V battery.

3. Operating Instructions

Once all connections are securely made and polarity is verified, the solar panels will begin to supply power through the combiner cable to your battery charger/maintainer. The charger/maintainer will then regulate the power flow to your 12V battery.

• Ensure solar panels are exposed to direct sunlight for optimal performance.
• Monitor your battery charger/maintainer for charging status indicators.
• This cable is designed for parallel connection of solar panels to increase current, not voltage.

4. Maintenance

The Sunway Solar Panel Combiner cable requires minimal maintenance. Follow these guidelines to ensure longevity and reliable performance:

• Regular Inspection: Periodically check the cable and connectors for any signs of wear, damage, or corrosion.
• Cleaning: Keep connectors clean and free from dirt, dust, and moisture. Use a dry cloth to wipe them if necessary.
• Storage: When not in use, store the cable in a dry, cool place away from direct sunlight and extreme temperatures.
• Avoid Stress: Do not bend or pull the cable excessively, especially near the connectors, to prevent internal wire damage.

5. Troubleshooting

If you encounter issues, consider the following common troubleshooting steps:

• No Power Output:
  • Ensure all SAE connections are secure and fully seated.
  • Verify solar panel exposure to adequate sunlight.
  • Check the polarity of all connections. Incorrect polarity will prevent power flow.
  • Confirm that each solar panel is functioning correctly individually.
• Low Power Output:
  • Ensure each connected solar panel meets the 30W maximum output and 15-18V voltage requirement. Overpowering a panel may lead to reduced efficiency or damage.
  • Check for any shading on the solar panels.
  • Inspect the cable for any visible damage or kinks that might impede current flow.
• Polarity Issues:
  • If you suspect reverse polarity, immediately disconnect all components.
  • Use a voltmeter to re-verify the polarity of each solar panel and the combiner cable.
  • If a polarity mismatch is confirmed, a SAE Polarity Reverse Adapter may be required for compatibility with certain solar panel brands.
