A direct-current (DC) solid-fuel grill comprises a direct-current power source and a direct-current auger motor receiving power from the direct-current power source. The DC solid-fuel grill may also comprise a solid-fuel grill component configured to be driven by the direct-current auger motor. A direct-current controller or processor is in communication with the direct-current auger motor. The direct-current controller or processor is configured to provide at least a first signal to the direct-current auger motor causing the solid-fuel grill component to actuate at a first velocity, and a second signal to the direct-current auger motor causing the solid-fuel grill component to actuate at a second velocity.
