These are your regular home fridges we all grew up with. They run off 120v power and are generally plugged into the grid. They invariably include a freezer unit. When plugged into a solar power system (including solar panels, batteries, a charge controller, and an inver), these AC refrigerators can be effectively used as off-grid fridges running off DC power generated by the solar system.
