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.

DC system controls

A heat transfer unit includes housing that includes a compressor, a condenser, one or more fans, and an air duct disposed on a side of the compressor unit. The heat transfer unit is configured such that the unit may operate in a mini-split or stacked configuration.

Modular heat transfer units

A DC-powered refrigeration 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.
