Preparing For An Off-Grid Winter

Winter is here and with it, the cold. So far we’ve had some nights down in the low 30’s, and maybe even below freezing. Last year I did a post about my first winter, which you can read here. Since I do live off grid, there are quite a few steps I take to get ready. So today I thought I’d share some of those here.

Preparing For An Off Grid Winter

The biggest consideration I make is the fact that with the days getting shorter and in the winter, you tend to have more overcast skies. This means one thing: less solar gain for my panels. Now in the design of my system (I talk about my tiny house solar setup here), I calculated everything based on the winter months when solar exposure is the least. This means in the summer my system is making way more power than I can use. But in the winter, a low producing day will actually be enough to power everything I need.

With this in mind I make my preparations.

Generators:

The first thing I did was get out both of my generators and check them out. I have two generators for two very specific functions: a small super efficient and quiet one to run for real time power and a larger one that just dumps a ton of power out at 240V to refill my batteries quickly. I make sure that things look good, I start them up, and I change the oil even if it doesn’t need it. While doing this I discovered that my larger generator for whatever reason was only putting out 120V out of my 240V outlet, which is a real problem because my inverter requires 240V to trigger its power shunt to charge the batteries.

Luckily it was still under warranty and I checked this now, not when I really needed it, and was able to get it to the shop to get fixed for free. With the two generators squared away and in good working order, it was time to move onto the consumables that go with them.

Consumables For Generators:

I first checked my stock of spark plugs, oil and fuel stabilizer. As a rule I try to keep these things on hand so I can ward off “Murphy,” AKA Murphy’s Law: anything that can go wrong, will go wrong. Sometimes a spark plug just gets too gummed up, and it can be easier to replace it with a new one rather than clean it off; at $1.58 each I usually just swap it out for a new one.

The oil I just keep on hand in case there is a leak or I would need to drain it for some reason. I prefer to use a higher grade of synthetic oil which my generators can use for longer run time. I also keep fuel, gloves, a catch basin and paper towels to change when I need to. Finally I have a large bottle of Sta-bil which is a fuel stabilizer that allows you to maintain the quality of gas for a longer time; I make sure it’s the type for ethanol because gas with ethanol mixed in goes bad faster. Ideally I’d seek out non-ethanol gas, but it’s increasingly hard to find and it’s not offered near my house reliably.

GasOffSingleWipeThe last consumable I stock up on is this product I found called “Gas Off Cleaning Wipes.” Initially I thought this was a silly product, but I tried one and was completely sold. It always seems that I had to fill up my generators right before I would go to bed and no matter how careful I was, my hands would always get a little gas on them.

These little wipes remove that gas smell, which isn’t normally a big deal. I noticed that the odor was very strong because when I sleep, I curl my arm up so my hand is near my face. These wipes remove the gas smell and for a few bucks, I now keep a pack handy.

Gasoline and Propane:

Going into the winter I always start with all my tanks full. I currently have six 5-gallon tanks, four 2.5-gallon tanks, and six propane tanks. I never need this much at one time of course, but I find its easier to load it all up and do it all at once.

For gas, if I have any remaining gas in the tanks, I put it in my car. This allows me to only have gas that is at most a few months old. With empty tanks, I put Sta-bil in each tank, then fill them up. I am on the hunt for gas pour nozzles without the EPA spill free spouts because they are a royal pain and I usually end up spilling because of the nozzle being so awkward to use. I then store the gas out of sight, but still in a well ventilated space away from my house.

Propane is a reality of living off the grid. While I had really wanted to get away from fossil fuels altogether, heating water on electric is a huge power suck. Also, I love grilling out, but don’t always have time to get some charcoal going. Right now I run about 3 months on a single 20lb bottle of propane for my water heating. I also use a 20lb bottle for cooking (grilling and stove top) every 3-4 months. So I always keep 2 tanks hooked up and 4 in reserve.  I’m thinking about buying two more because I find it easier to fill up a bunch at once than do a lot of little trips. One tip for refilling your propane: getting refills is much cheaper and you get more propane for your dollars at a refill station.

Planning Redundancies:

With living off the grid, you always need to have a backup plan, and a back up to that back up. Two is one and one is none. In this case my main concerns are my ability to heat, my ability to cook, and my ability to get water.

With this in mind I went out and stocked up on 1lb propane bottles for my back up heater. The heater is a Mr. Buddy heater that costs about $35 and is straightforward to use and pretty portable. I’ve used it in the past and it’s worked well, so it’s a great back up heat source if I need it. They do sell an adapter for a big propane tank, but I find the 1lb tanks convenient in the rare instances that I do need it.

For water I always keep a few gallons on hand for drinking, cleaning and cooking. In a pinch I can heat some of it on the stove and do a sponge bath if the hot water heater were to go down. The heating of the water can be done on my portable stove top which runs on butane cartridges. All of this is just handy to have ready to go if I ever were to need it, but it isn’t for the everyday; anything to help keep Murphy away.

Keeping Your Solar Panels Clean:

With the fall and the winter, it’s like Mother Nature is out to get you sometimes, and coming up with ways to cover your panels happens a good bit. Whenever your solar panels get covered, even partially, your power production can start dropping. In the fall it’s leaves, and in the winter it’s snow. It’s also a good time to clean the panels of dust and grime.

Food and Home Provisions:

Since I’ve been doing so much preparation for nesting I also took the chance to clean out my house and then stock up stuff for the house. I got extra tissues, paper towels, trash bags, soaps, shampoo, and other stuff like that. I also started building out my pantry a little bit more by picking up general cooking ingredients, soups, snacks, and warm drink options.

Heating A Tiny House:

Things have changed a good bit with the installation of of my solar and mini split system. I am happy to report that the mini split has been able to cool and heat my house very effectively, to the point that I was able to keep my house at 64 degrees on a 98 degree day easily and with the cold nights dipping down to freezing I was able to keep my place very toasty.

The beauty of the mini split is that I have a lot of control over the temperature, including the ability to set a range so it automatically heats when it gets too cold and cools when it gets too hot. I can set schedules, have it be motion activated, and all is done with just a simple press of the button. Compared to wood heat, this is a much more superior way because often wood heat get too hot and many times you find yourself waking up in the morning to a cold stove. Since it’s solar, I don’t have much guilt about setting it to my ideal preferences and there’s no chopping wood. I feel like the tiny house mini split evangelist here, but I love this thing.

Wrapping Up:

So all in all I have just been trying to get a lot of last minute things done so I can head into winter with everything in place, the house cleaned and well stocked. Between it dropping temperatures and holiday parties, seeing friends and other things filling up this busy time of year, I’m glad to get ahead of things. Living off the grid certainly does come with its own set of considerations, but I’ve found it to be a very comfortable life and some simple preparation makes it pretty easy to do too.

Your Turn!

My First Winter In A Tiny House

After getting back from Croatia I’ve been learning a good bit about living in my tiny house in the winter. This December in Charlotte has been breaking records left and right for how cold it has been. Most mornings when I wake up it’s been in the 20’s which is very cold for this time of year.

The real issue for me has been right now I’m running off a generator and propane heater for my heat. Soon my solar panels will be installed and I can shift to my mini split. The generator has been working well, but because of how energy intensive the heater is and how cold it is, a full tank will only last about 3-4 hours. The propane heater works great too, a 1 lb propane tank will last about three hours.

First Winter in a Tiny Home: How to prepare

My strategy has been mainly to heat the house up for about an hour while I get ready for bed and then shut things off. With the propane heater, its a “catalytic” heater that while is technically a flame, it is more efficient and doesn’t use up as much oxygen as a open flame would. I don’t want to leave it running when I sleep because of it being a flame and also the danger of low oxygen. The heater has a low oxygen detector that will shut it off if it comes to that, but I don’t want to chance it regardless. Once I fall asleep, I’m fine until I wake up anyway.

One thing that I’ve learned is that the floor is always cold. Being on a trailer there is obviously an air gap below the trailer. I know a lot of people have used skirts for their house, but I’m not a fan of the look and its not windy in my location, so I’m not sure how effective it would be. It may come to be installing a skirt of a sort, but I think I’d like to start with trying an area rug. I think this might be an easy way because I noticed that when I stepped on a piece of cardboard that I happened to have on the floor, it seemed to do a pretty good job of feeling warm on my bare feet.

So far it’s been a pretty cold winter in my tiny house. That’s about to change.

First Winter in a Tiny Home: Preparations

Very soon a solar panel system is going in that will change my heating situation drastically. I will have a huge battery bank that will let me run my mini split and keep my space heated and on a timer, without the danger of an open flame or running the generator. The timer will be really helpful because I can drop the temperature when I’m asleep nestled under my covers, but then ramp back up right before I wake up and have to get out of bed. I’ll also be able to set it to maintain a minimum temperature, which will be nice because I can keep it a reasonable temperature, but not draw a ton of power.

The other thing I’ve noticed is since its been so cold outside, I’ve been inside my house more and wanting to go outside. Nothing really bad, but I’ve been so used to be going for long walks and just enjoying the weather since its so much warmer in Croatia, right now it’s a little too cold to just spend time outside. I have been spending some time at the gym, at cafes and I also went out and bought an outdoor fire place to have a fire pit at my tiny house. All of these have been great for handling this need to get up and do something. I think this will subside when I get power set up because I can then get Internet hooked up and set up my desk. That will help a lot.
