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