Lights, refrigerators for "off the grid" lot trait

I am not sure what the specific item name is, but when you hover over an item it tells you if it works with the off the grid trait. There is one fridge I think that works. Theres a good amount of lights that work, mostly candles or anything with a flame.

There are some things that don't say they work off-the-grid, but they still function a little. I thought refrigerators wouldn't work at all, but apparently you can still put things in them and get food out of them. Grills and candles work, but the lamps that look like oil lamps are actually electric. I haven't gone through and tested everything, but these were the things I was most interested in!

Thanks for the replies ☺. Decided the off-the-grid lot trait wasn't for my sim after all; can only cook two things & the water is brackish & tepid, which gives my sim tense/uncomfortable moodlets. May try again sometime in the future.....
