Question about Ctek D250SE Lithium DC/DC Converter 12V

The CTEK D250SE battery charger can draw power from several sources without a mains connection:

- Alternator: it can draw power directly from the vehicle's alternator, including vehicles with smart alternators.
- Solar panel: It has a built-in MPPT solar controller that allows it to draw power from a solar panel.
- Wind generator: It can also draw power from a wind generator when connected to the solar input.

These multiple energy sources make the device particularly flexible for use in vehicles without access to mains power.
