Hi, folks. Does anyone have any insights regarding sizing a portable generator for home backup? My electrician is prepared to set me up with a (legitimate, up-to-code) method for backfeeding my panel in the case of a power outage. I'm barely a novice in terms of electrical work/home wiring and so please don't ask me to provide details regarding his methods or materials.. just know that he is a licensed electrician!
That being said, any recommendations regarding what'd be an adequately sized portable generator to provide backup power for my home? In terms of usage/load, my goal would be to maintain power to the pumps/computer associated with my propane boiler (home heat + hot water), well pump, freezers (one chest, one upright), refrigerator, air exchange system, and then I guess some lights and probably a laptop/phone charger. I don't own air conditioners nor would I plan on running power tools during a power outage. Additionally, I think I could handle the responsibility/"burden" of unplugging my freezers once they got to temp (just meaning that some stuff wouldn't have to stay plugged in/operational constantly). My primary concern would be to keep my boiler functioning (as this will provide my home heat in addition to my woodstove) and my well pump operational.. as well as my fridge and some lights I suppose.
In light of all this, would a 4,000W generator suffice? Or is that cutting it close? Is something like 6,500W more appropriate?
I should also mention (perhaps very important) that my power doesn't go out very regularly. Furthermore, if and when it does go out it rarely lasts more than a few hours. And again, this is perhaps twice a year. I just happen to live in a very cold part of the country (Northern Minnesota) and a modestly priced generator seems like reasonable "insurance" against frozen pipes!
I'm really happy I joined this site not too long ago. As such, I look forward to hearing what some of you have to say.. Thanks!
