Can Wind Damage Portable Generators?
Ever had the wind rip your gazebo out of the ground? Now imagine what it could do to your generator. One big gust is all it takes to knock it over, soak the electrics, or send deadly fumes in the wrong direction — but don’t worry, we’ve got the fix.
How Long Can Wind Damage Portable Generators?
It doesn’t take much — one solid storm can be enough to knock out your generator for good. A sudden gust, a flying branch, or a burst of sideways rain can damage critical parts in minutes.
And here’s the kicker — some damage doesn’t show up until weeks later, like internal corrosion or engine wear. If your generator’s knocked over or left exposed, it could be out of action right when you need it most.
The key? Get ahead of the storm. A few small adjustments now can save a costly replacement later.
The Physical Dangers of Wind to Your Generator
Wind doesn’t just blow things over — it throws stuff around and finds every gap in your gear. Portable generators, especially the smaller or cheaper ones, aren’t built to cop a beating.
If they’re not secured properly, the results can be messy.
Debris and Flying Objects
During a storm, your backyard turns into a battlefield. Branches snap off trees, patio chairs take flight, even bits of roofing can come crashing down.
When one of those hits your generator, it can break the exhaust system, pierce fuel lines, or smash the control panel. Even small stuff like mulch or leaves can clog your air vents and mess with airflow.
The worst part? You often won’t notice until the generator stops mid-use. Not exactly ideal when you're trying to keep the fridge or lights on.
The Risk of Your Generator Tipping Over
Some portable generators are pretty top-heavy. Add a slick surface or uneven patch of lawn and a bit of wind, and suddenly you’ve got a tip-over hazard.
When that happens, you risk spilling fuel, leaking oil, or damaging internal components. A knocked-over generator might not start again — or worse, it might become a fire hazard.
A level surface and some simple anchoring gear can make a world of difference here.
The Hidden Damage Wind Can Cause to a Generator
Not all wind damage looks like something out of a disaster movie. Some of it is subtle — and that’s exactly what makes it dangerous.
Moisture and dust are sneaky culprits. They sneak into tiny openings and slowly wear down your generator from the inside out.
Moisture and Water Ingress
Rain driven by strong wind has a nasty way of getting where it doesn’t belong. That includes your generator’s plugs, switches, vents, and internal wiring.
Even a small amount of water can cause corrosion, short circuits, or electrical faults. And if the unit’s running when it gets wet, you could fry the system entirely.
That’s why elevated bases, breathable covers, and proper drainage matter — especially in flood-prone or coastal areas.
Clogging from Dust and Debris
Live in a dry or rural area? Wind can whip up dust, bark chips, grass cuttings, even gravel. All of that can clog your air filter, jam your cooling fan, or choke your exhaust.
Once airflow is restricted, your generator runs hotter. That can trigger automatic shutdowns or long-term engine wear.
The solution? A clean, open space with regular maintenance. Don’t let your generator breathe in rubbish.
Protecting Your Generators from Storm Threats
Your generator might be rugged, but it’s not invincible. If you live somewhere prone to wild weather — especially in northern QLD, coastal NSW, or anywhere with open paddocks — you need a storm-ready setup.
With the right protection, your generator will handle the rough stuff like a champ.
Do Generators Attract Lightning?
Not usually — they’re not tall or made to conduct electricity like metal poles. But that doesn’t mean they’re off the hook.
Lightning doesn’t need a direct hit to cause chaos. If it strikes a tree, fence, or power lead nearby, the surge can fry your generator’s electronics. Even plugged-in appliances can be affected.
So during lightning storms, disconnect unnecessary loads and avoid running your unit unless absolutely essential. Surge protectors are also a smart move.
What Should You Do First If You Suspect Carbon Monoxide Poisoning?
If anyone near the generator starts feeling dizzy, light-headed, or nauseous — switch it off straight away and get everyone outside into fresh air.
Carbon monoxide is invisible and odourless, but deadly. It builds up fast, especially when wind redirects fumes back into your home.
Call emergency services and don’t re-enter until it’s safe. And always use a battery-powered CO alarm near bedrooms. It’s a $30 life-saver.
Securing a Portable Generator for High Winds
You don’t need to concrete it into the backyard, but you do need to secure it properly. Start with these:
-
Anchor lightweight units with sandbags, screw-in stakes, or tie-down straps
-
Keep it elevated on gravel or blocks to avoid water pooling
-
Use proper covers — not plastic tarps that trap heat
-
Keep a 3-metre safety zone around the generator, free from leaves and clutter
-
Always check the wind direction — fumes should blow away from your home, not towards it
If the storm gets particularly hairy — gusts above your generator’s safety spec, or lightning nearby — shut it down until conditions improve.
Final thoughts
Wind might not seem like a big deal, but for your generator, it can cause serious drama. Whether it’s physical damage from flying junk, internal wear from dust or water, or safety risks from fumes and sparks — a storm can knock out your power and your backup.
But the good news? It’s easy to protect your gear. With the right cover, a solid anchor, and smart positioning, your generator will be ready when the power grid gives up.
Get ahead of the weather, prep properly, and you’ll stay switched on — even when the skies are doing their worst.
