DJI D12000i Generator Slow Charging

Cause:

1. There is an error with the DC Module on the generator.
   1. The DC Module is what sends and regulates power from the generator to the charger in the generator.
2. There is an error with the charger in the generator.
   1. The charger can have a few components that go bad including the cord or the whole charger itself that may need replacement.
3. Generator maintenance is required.
   1. The charging station tracks the running hours and at certain intervals if the maintenance has not been performed and codes have not been cleared.
4. A charger update is required for the charger in the generator to function properly.
   1. Just like the drone and controller, the generator charger has a firmware that affects the efficiency and performance of the machine.

Diagnosing:

1. While attempting to charge a battery on the side of the generator where the battery plugs in, observe the lights on the charging station.
   1. There will be a list of what different codes require above the charger on the side of the generator that will be able to tell what is potentially wrong with the generator.
2. For firmware related issues you can plug a T40 controller into the charger and see if there is an update available.
   1. There will be an option to update the firmware of the charger just like the drone or RC but under the “charging devices” section.

Solutions:

1. DC Module Issue
   1. Replace the DC Module.
2. Generator Maintenance
   1. Complete the maintenance required and clear the code with a controller
3. AC Module
   1. This is an error with the charger inside of the generator. May require replacing the charger or further inspection of components (wires, plugs, etc.)
4. Firmware Update
   1. Plug the T40 controller in and update from the device screen.
