A number of off grid cabin setups use DC distribution within the house and purely DC appliances (fridge, LED lighting, etc). Usually in the context of places that are very far from a grid, with wood heat, or tiny home size off grid setups.

Think of it something like planning the DC loads on a 55 ft sailboat.

People who do this will usually have one small 300 to 500W sized DC to ac pure sinewave inverter for laptops and chargers of small consumer electronics.
