Off Grid refrigerator – updated

A while back we wrote about the performance of our refrigerator and presented the power details.  However, one item was probably missing in the data.  That is, how much power does that thing take when its summer?

I pulled out our trusty Kill-o-watt power monitor and set up the test a couple days ago, and began recording .   Unfortunately, we are not in the middle of a hot spell which would raise the ambient temperature in in the kitchen to 80F or more.  For this test I’d say the average temperature remained between 70-72F.   This is better

What if it doesn’t work on my genverter?

Sometimes we let fear stop us from moving forward.  Here’s a good show stopper kind of question; “what if my new <insert appliance here> doesn’t work on my genverter?”  It may not be the end of the world, and often we can adapt our behavior to make it work.  Remember our motto, “Adapt, Improvise, and Overcome!!

rethinking off grid cooking [2]

Jackie continues this series with some tasty barbecue beef.  Its time to re-evaluate power assumptions about things like crock pots and determine if these  appliances are practical in the right sized genverter system.  In this recipe, we capture the power data for the crock-pot on the high setting. Next in the series, we’ll look at another common kitchen appliance.  See the first installment at; Rethinking Off Grid Cooking [1]

Rethinking Off Grid Cooking [1]

Jackie starts of this series with some tasty stew.  Its time to re-evaluate power assumptions about things like skillets and crock pots and determine if these useful appliances can be practically used in the right sized genverter system.  If so, you can move off grid sooner with less kitchen equipment? Next in the series, we’ll look at another common kitchen appliance.

One thing I miss about not having grid power is being able to cook with most electric appliances. [Marshall has the exception for his Espresso though]   I recall asking about the electric food dehydrator. about the bread maker, and about the crock pot – all No.

Keeping a refrigerator in an off grid environment is a challenge and expense.  In this series, we cover our experience with several units.  In the previous Tips 2 & 3, we spoke of the new Frigidaire unit, here I’m seriously pleased to follow up on that last bonus tip with good power news

One of the more difficult parts of creating and living within your power budget is getting good power data to use.  Yes you can “worst case it” by using UL power listed on appliances.  The result, however, will be a moderate to largely exaggerated system budget.   Yes, you will have more than enough power, yet the price tag may scare you away from your off grid move!   So realistic power numbers are crucial.
