Abstract
A DC-powered system may include controls configured to switch between available DC power supplies and manage the refrigeration system in accordance with one or more methods. The one or more methods of the control system may include multiple tiers of power management, including, e.g., maximization of power usage when on a photovoltaic power supply to subcool a refrigerated load.
