Frequently asked questions

Can I connect a DC/DC converter directly to a solar panel?

Our DC/DC converters do not have MPPT control. With a direct connection,
the optimal operating point of the solar module is therefore not tracked automatically.

Important: The DC/DC converter must not be connected between the solar module and the MPPT controller.

For stable and efficient operation, we recommend a suitable solar or MPPT controller or power supply via a battery with an upstream solar controller.

Why must the entire input voltage range be considered?

The input voltage must not at any time exceed the permissible range of the converter. Therefore, take into account not only the nominal voltage, but also voltage peaks, charging voltages, and potential open-circuit voltages.

For solar modules, the maximum open-circuit voltage at low temperatures is particularly critical.

Which DC/DC voltage converter do I need?

For the selection, we require:

  • the full input voltage range,
  • the desired output voltage,
  • the maximum current or power requirement,
  • information on whether galvanic isolation is required,
  • a brief description of the application.

Please send this information along with the desired quantity to info@bauer-united.com. We will be happy to assist you with your selection.

How must a voltage converter be fused?

The positive lead should be fused as close as possible to the power source or the vehicle's electrical system tap. The fuse and cable cross-section must be appropriate for the maximum input power, cable length, and installation.

If you are uncertain, please send us the item number along with details regarding input and output voltage, power, and cable length.

Why does my device charge slowly when connected to a 5V converter without a USB charging controller?

A 5V converter only provides the output voltage. Even a high current rating only means that the converter can supply this current as a maximum. Without a USB charge controller and supported charging protocols, the connected device may not recognize the available charging power and will therefore limit the charging current.

For fast and reliable charging, we recommend a 5V converter with integrated USB charging electronics and suitable charging protocols.
