Since your Jackery power station recharges normally via AC wall outlets, we can follow a few troubleshooting steps to narrow down whether the issue lies in the cable, the solar panel, or the connection:
1. Check Connections & Adapters
· Ensure all charging cables and connectors are firmly plugged in with no loose connections.
· If you are using a SolarSaga series panel or connecting multiple panels, please verify that you are using the correct original adapter and proper parallel setup.
2. Observe the Display Screen
When solar charging, check if the LCD screen displays the charging icon and real-time input wattage. If both are missing despite a secure connection, no voltage is entering the device.
3. Test Solar Output (If a Multimeter is Available)
· In bright, direct sunlight (unobstructed by glass, shade, or dust), measure the Open Circuit Voltage (Voc) at the end of the solar cable using a multimeter.
· Normal Voc should typically read around 25V (±5%). If the reading is 0V or significantly lower than specified, the solar panel or built-in cable may be damaged.
4. Check Environment & Temperature Symbols
· Shading: Even partial shadows from trees or windows can drastically drop solar output.
· Temperature: Check if the power station screen displays high/low-temperature protection icons, as extreme temperatures will temporarily stop solar charging.
· Error Codes: If your screen displays an "F7" code, it indicates that the solar input voltage is outside the supported high/low limits.
5. Cross-Test with Car Charger
Please try charging your power station using the 12V car charging cable. If the screen lights up and displays input power via car charging, this confirms that the power station’s DC charging port is working properly.
