Issue Description:

The display of the DJI Power indicates "ERR66", and the DJI Home app prompts "Communication error between main board and inverter".

Solution

1. If the power supply is currently connected to the mains, disconnect it from the mains power.
2. Power off the power station by pressing and holding the power button. Then press and hold the button again to power it on after 30 minutes.

3. Check if the power supply firmware is the latest version. If not, connect the power supply to DJI Assistant 2 (Power Series) or the Home app (except for DJI Power 500) to update to the latest firmware.

4. If the above solution does not resolve your issue, please contact DJI Support.
