Charging failed during the test

When a device with solar panel fails to charge, diagnose step by step as follows:

Verifying Current Battery Voltage

Note: The voltage shown in Ecotopia is not the real-time volate of the device. It is the voltage when the device transmits data to the server last time. Connect the device directly with the Ecotopia App and check the live voltage on the INTELINK page.

• If you cannot connect the device, place it under sunlight (clear sky, direct sun exposure, not through glass or other transparent materials) to charge, then try connecting again. If it still fails, follow the guide to activate the “sleeping” battery, and reconnect to check the voltage.
• If the device connects successfully but the voltage shows no obvious change, proceed to the next step.

Power-off and Verifying the Charging

1. Power off the device and charge it under good sunlight (clear sky, direct sun exposure, not through glass or other transparent materials). Click here to check how long does it take to fully charge the device.

   The ideal testing environment is in regions with minimal cloud cover, strong sunlight, and more than 5~7 hours of effective daily sunlight, such as coastal Mediterranean areas or mid-latitude regions during summer.

   When testing in environments with less favorable sunlight conditions, such as high-latitude regions or mid-latitude regions in winter, please extend the testing duration accordingly.

2. After charging for a while, connect with the Ecotopia App and check the voltage on the INTELINK page.

   • If the voltage still does not increase, contact your sales representative.
   • If the voltage increases as expected, continue with the power‑on test.

Power-on Test Verification

For comparison, test the device alongside other normal devices under the same environment and settings.

1. Configure the device with the default settings:

   • Recommended default settings
     • GNSS interval: 1 hour
     • Transmission interval: 8 hours
   • For small‑battery devices (e.g., ULTRA 5G P1):
     • GNSS interval: 6 hours
     • Transmission interval: 1 day

   If you are not sure about the default settings, contact your sales representative.

2. After powering on and delivering the settings, place the device in the following environment:

   • Clear sky with direct sunlight; not through glass or other transparent materials.
   • Open area, away from high walls, metal, strong magnetic fields, and liquids (e.g., wet ground).

   Place one or more normal devices of the same or similar model for comparison. And make sure that the initial voltages of the devices are close and setting parameters and test duration is the same. Side‑by‑side comparison under identical conditions helps determine whether the test device’s charging function is abnormal.

3. After 1 ~ 2 days, review the voltage and light intensity curves in Ecotopia’s data analysis.

   • If voltage follows light with normal day/night fluctuations and rises overall, the device is operating normally.
   • If voltage does not track light normally, shows abnormal fluctuations, or fails to increase, contact your sales representative.

Notes for Non‑solar Charging Devices

For non‑solar charging devices that fail to charge, consult your sales representative for further support.
