I just want some big fridge/freezer manufacturer to build a "green fridge" with a 24-48VDC port and include a ~100W panel that anyone could wire up. Auto-switch to 120VAC as needed. Newer fridges run a variable drive motor, so the circuitry required has gone down.

These exist as camping fridges (ex: https://www.amazon.com/DOMETIC-75-Liter-Portable-Refrigerato... there are also a few different full-size deals floating around. From what I've seen, these are a terrible idea for normal home use: they're eye-wateringly expensive, and for the sake of efficiency you give up a lot of nice features like air circulation and humidity control that are commonplace in far cheaper ordinary 120v AC fridges. Great for short-term use, but if you plan on keeping food fresh for weeks instead of a few days, you're gonna be annoyed.

The heat pump version of this exists, but I'm not aware of a fridge. https://signaturesolar.com/eg4-hybrid-ac-dc-solar-air-condit...
