Getting ready for your first time living off-grid in winter? It can be a bit daunting heading into it, so in this article we list some recommended tasks to complete before winter really sets in. We've compiled advice from our customers, colleagues, and Facebook group members to try and cover off as much as possible. 

Check your generator:

You’re probably going to need your generator a fair bit over winter, so take a moment now to do some maintenance or go get it serviced. It’s always nicer to be messing about with your gene on a clear autumn day than a wet winter day!  If you haven’t used it before, be sure to test it now too.

Check your oil and fuel levels, top them up if needed, and consider getting some extra to have on hand when you run low. If your generator didn’t get much use over summer, the fuel might be reaching its shelf life and need to be replaced. Check the owner’s manual for any other maintenance that’s required - it might be a warranty condition too.

If you don't have a generator, we highly recommend getting one if you plan to live off-grid full time (and don't already have a power contingency plan). We've got an article all about generators for beginners here

Prep your solar panels.

You probably haven’t been too worried about your solar output over summer, but as the sun-hours get shorter, now’s the time to make sure they’re as efficient as possible! Before it gets too nasty outside, give them a good clean to get any accumulated dust and debris off them – we have an article all about how to do that here. If you live in an area that gets snow, it’s good practice for clearing off the snow!

While you’re up there, give all the connections a quick check to make sure they’re all secure and undamaged.

If you’ve got an adjustable mount (and some help), you might consider adjusting the tilt of your panels to optimise the amount of sun you catch. If not, there’s no harm in leaving them in their original position, especially if it’s already a compromise of winter and summer angles. Learn more about positioning.

Revisit your power use habits.

As the days get shorter and your solar power generation is less, you might need to reduce your power usage if you increased it over summer. Average daily sun hours in winter are less than half that of peak summer, so you’ll have a lot less power generation to work with than what you may have gotten used to using.

Living off grid in winter means any of those high power-draw appliances, such as induction cooktops and corded tools, should go back in storage.

You may also have to cut down on how long you’re running certain appliances or plan them for sunny mornings – keep a closer eye on the battery voltage throughout the day so you have warning if you’re getting close to running out of power.

You’re also far more likely to have multiple poor weather days in a row, meaning you will struggle to recharge your batteries fully, on solar, and might not be able to maintain normal power use. This means the most important task is keeping an eye on the weather, as knowing when these periods are coming is crucial in allowing you to prepare for them by reducing your power usage or getting the generator going. Read more about how long periods of poor weather affect power here.

Replenish your LPG reserves.

If you rely on LPG for cooking, heating, and showers, you’ll start going through it a bit quicker as the weather cools down and your usage increase. Check how much you’ve got left in your tanks and book a refill or swap your cylinders in town before you run out. The last thing you want in the middle of winter is your shower suddenly going cold! Take a second to check all your lines for damage while you’re out there too.

Be prepared for complete power outages.

Just in case something goes completely wrong, like your batteries are flat and you can’t use the generator etc, think about how you could get by for a couple days with no power. Non-perishable food stocks, and power banks for your phone are two of the best things to have on hand to help you get by without having to leave your property unnecessarily – especially important if you live somewhere at risk of having the roads closed.

Prep your woodstove.

If your woodstove hasn’t been used much over the warmer months, take some time to inspect it before you need it again. You’ll want to sweep the chimney, empty out all the ash, and check the flue, firebricks, damper, and door glass for any damage. Then, check your dry wood reserves to ensure you’ve got enough to last a while! If you’re chopping down the trees yourself, doing it at least 6 months ahead gives it time to dry out properly.

Protect your building from weather

If you’ve got a new building or have just relocated one, you might have a few chores to do to ensure the coming weather won’t damage anything. Things like sealing the exterior and painting the cladding to prevent premature degrading might be needed. 

And the most recommended tips when we asked off-gridders:


Thick merino socks, winter sheets, and a good thick duvet, plus thermal curtains, double glazing, and insultation batts are all good ways to keep your body temp up, and your home’s.

Don’t stress the mud too much

For most places in New Zealand, winter means rain rather than snow, so off-grid properties tend to get a bit muddy – and so will you.

One recommended prep is covering in your deck to create a hybrid indoor/outdoor space for hanging washing in or keeping muddy clothes/boots somewhere they won’t get wetter but won’t clog up the living space.

Another is creating dry pathways, using leftover pallets to create a boardwalk for example, so you can minimise the amount of mud you have to walk through. Of course, living off-grid means living outside more, and getting wet and muddy is just part of it!
