-Dumb converters output a single voltage (see above).
+"Dumb" converters output a single voltage and work fine when solar charging is present (see above).  In this scenario the 12v power supply can is set to ~13.x voltages to provide "float" support while on shore power.

+If loads are run off the converter in the daytime the converter will just be supporting the solar yield and can be rather small.  If used at night the converter will be carrying the whole burdern should be sized to your expected loads ([[https://amzn.to/2WNSIDL|20A]], [[https://amzn.to/3jwQGBO|40A]], whatever).

   * secondary use of charge controller as a spare if needed
-If you do not need smart charging an adjustable voltage power supply could do the trick.  Since by definition the batteries aren't cycling when on shore power you could adjust it to something like 13.2v and let it "float" charge over time.
