6. Setup Instructions

Follow these steps to set up your solar power generation system. For a visual guide, please refer to the installation video below.

1. Connect Solar Panel to Charge Controller: Connect the solar panel's output cable to the designated solar panel input terminals on the solar charge controller. Ensure correct polarity (positive to positive, negative to negative).
2. Connect Battery to Charge Controller: Connect the battery to the battery terminals on the solar charge controller. Again, observe correct polarity. The controller should display battery voltage.
3. Connect Inverter to Battery: Connect the power inverter directly to the battery using the provided battery clips. Connect the red clip to the positive (+) terminal of the battery and the black clip to the negative (-) terminal. Securely tighten the connections.
4. Connect DC Load (Optional): If you have a DC load, connect it to the load terminals on the solar charge controller.
5. Power On: Once all connections are secure, turn on the power inverter using its ON/OFF switch.

7. Operating Instructions

7.1. Solar Charge Controller Operation

The LCD display on the charge controller shows real-time information such as battery voltage, charge current, and load status. Use the MENU, UP, and DOWN buttons to navigate and adjust settings.

• Browsing Interface: Press the MENU button to cycle through different display interfaces (e.g., Float voltage, Discharge reconnect, Discharge stop, Work mode, Type of battery).
• Setting Parameters: In interfaces 2-5, press and hold the UP button for five seconds to restore defaults. Press and hold the MENU button for five seconds to enter manual settings. The number will flash; use UP/DOWN to adjust values. Press MENU for 5 seconds to exit setting.

7.2. Power Inverter Operation

• Powering AC Devices: Plug your AC devices into the universal socket on the inverter. Ensure the total rated power does not exceed 500W.
• USB Charging: Use the dual USB ports to charge mobile phones, tablets, and other USB-powered devices.
• LED Indicators: The inverter has green and red LED lights. Green indicates normal operation. Red indicates a protection status (low voltage, high voltage, over temperature, over load).
• Battery Level Display: The LED Battery Level Bar shows the battery capacity (each lattice represents 20% power). It will flash when the battery is low, indicating a need for charging.

8. Maintenance

• Keep all components clean and free from dust and debris.
• Regularly check all connections for tightness and corrosion.
• Ensure the solar panel is clean for optimal sunlight absorption.
• Store the system in a dry, cool place when not in use.
• Do not expose the solar panel to extreme mechanical stress or sharp objects.

9. Troubleshooting

• Inverter Red LED Lights On: If the red LED lights on the inverter illuminate, it indicates a protection status (low voltage, high voltage, over temperature, or over load). Turn off the inverter, identify the specific protection function triggered, and resolve the issue before restarting.
• Battery Level Bar Flashing: This indicates the battery is low on power and needs to be charged.
• No Power Output: Check all connections for proper seating and polarity. Ensure the battery is charged and the inverter is switched on. Verify that the connected device's power consumption does not exceed the inverter's rated power (500W).

10. User Tips

• Plug Compatibility: The inverter is available in 110V and 220V versions. Ensure the plug type (e.g., European, AU) matches your regional requirements or use appropriate adapters.
• Power Consumption: Always check the power consumption of your devices. It is recommended to use an inverter with a capacity 10% to 20% higher than your largest load to ensure stable operation.
• Battery Selection: The system requires a 12V battery (not included). Choose a battery type suitable for solar applications, such as deep-cycle lead-acid batteries (AGM, Flooded/OPEN, GEL).
