Wife is recovering from 2 surgeries, we're having a wind and ice storm. No power for 2 days. Generator dying, heading to town to get a new one.
Question: My fridge shows a power rating of 120v/6A, = 720W. Is this likely the starting surge rating, or the running rating? It's a samsung side by side with bottom freezer for reference. Want to get a small genny but big enough to run that fridge and maybe one other. (not necessarily at the same time) |

Usually rated for running. Starting will be higher, usually.

get at least an 8kw and you should be fine. for summer put a soft start on your air conditioning then you wont need to worry about start up current.
Im also recommending without knowing your loads. |

Good rule of thumb is 3x to start. So figure 18a/2160 to start. Remember that generators are usually rated the same way - two numbers are quoted, surge and running watts. You want to make sure the generator surge rating meets your start requirements.

Im also recommending without knowing your loads. I've got a 6KW generac I use for my well pump, but hauling it all over the property for the various fridges/freezers isn't working well for me. It much better suited to staying in the well house and running 30 min/day |

Ended up getting a predator 1400w before I'd seen the responses here. Thankfully it runs both of my fridges, though I haven't tested both at once yet. We'll see. It uses ~12% the fuel of the old generac, so that's a bonus

That is definitely not running watts of the compressor. Most modern fridge compressors draw less than 100 watts and they are inverter driven so no starting surge. 720 watts is the total power consumption of the entire system when everything is powered up including defrost heaters and door seal heaters. Heaters don't have a starting surge. I would plan on a running watt of 150 with occasional jumps to 400-500 with defrost heaters on. Very rarely would both heat sources be on at the same time as the compressor so it's very unlikely you would ever see a full 720 watts.
ETA, I'm not surprised it's running 2 fridges. |

Wind and ice storm? Any possible better options for food storage? Ice chests?

Awesome, thanks for this response |

Quote HistoryOriginally Posted By VoodooChile: Wind and ice storm? Any possible better options for food storage? Ice chests? Yes, but also no. I can transfer more stuff to the outdoor fridge and some ice chests, but I'm also taking care of my wife just a little removed from 2 major surgeries and our 3 kids so the less labor added to my day, the better. Not to mention that this is a somewhat recurring issue (we're living somewhat remote, power grid reliability wise anyways) so I want to have a long term solution that doesn't involve me wrenching on or dragging this aging generac all over the homestead |

Hope everything non-generator works out for you, OP.
