Summary Checklist for Your Choice
Choose the SR or ST-1200W if you want portability, low noise, and minimal investment for camping or caravans.
Choose the ST-2000, ST-3000, or ST-5000 if you have a stationary house/cabin and want to supplement solar panels at night.
Choose the ST-10kW — the largest turbine we sell — if you have heavy agricultural power needs, acreage, and a budget for proper mast engineering.
The vertical axis wind turbines listed on the BushLine Outdoor Equipment catalogue are categorised by physical design shapes, which dictate their ideal applications.

No.Wind turbines generate "wild" 3-phase AC power that changes voltage constantly with the wind speed. Connecting it directly to a battery or a standard solar inverter will instantly destroy your equipment. Youmustwire the turbine into a dedicatedWind/Solar Hybrid MPPT Controller with an integrated Dump Load Resistor. The controller converts the power to stable DC to charge your batteries safely.
-
You must match the turbine and its hybrid controller to the exact voltage of your existing battery bank:
- 12V: Best for compact mobile setups like caravans, 4WDs, and camper trailers.
- 24V: Great for medium-sized setups like off-grid sheds, cabins, and motorhomes.
- 48V: The gold standard for full off-grid home systems. Higher voltage means less energy loss through your wires and allows you to use thinner, safer cables.
-
When your battery bank becomes 100% fully charged, it stops accepting power. If a heavy wind storm hits at night when your batteries are full, a turbine with nowhere to send its power will "free-spin" out of control and physically fly apart. A hybrid controller fixes this by automatically diverting that excess power into the dump load resistor, which burns it off safely as heat and acts as an electronic brake to slow the turbine down.
-
No,that is the main benefit of the vertical design. Traditional horizontal "propeller" turbines create a high-pitched, annoying "chopping" noise. Our ST Tulip and Flower series utilise advanced omnidirectional maglev-style bearings, making them virtually silent and completely vibration-free, all you will hear is the wind. They are perfect for suburban blocks, tight caravan parks, and areas close to neighbours.
-
It will turn, but turning is not charging. The blades start rotating at about 1.5 m/s — a light breeze. Charging starts once the wind clears the cut-in speed of about 3.5 m/s, and output climbs from there — the rated figure is measured at 13 m/s (about 47 km/h). A gentle breeze keeps the turbine ticking over; it takes real wind to push real power into your batteries.
-
You should connect the wind turbine to a battery bank first, via a dedicated charge controller, rather than directly to an inverter. Connecting a wind turbine directly to a standard inverter will damage the equipment or cause the system to fail.
🔋 The Correct Wiring SequenceTo safely capture and use the power, your setup must follow this exact order:
- Wind Turbine: Generates wild, fluctuating 3-phase AC power as wind speeds change.
- Hybrid/Wind Charge Controller: Converts the unstable AC power into steady DC power. It also protects the turbine from over-speeding by applying an electronic brake during high winds.
- Battery Bank (12V/24V/48V): Acts as a buffer to store the energy. It absorbs sudden power spikes from wind gusts and provides a steady source of energy.
- Off-Grid Inverter: Connects to the battery, converting the stored DC battery power into standard AC power for your household appliances.
⚠️ Why You Cannot Skip the Battery
- Unstable Voltage: Wind speeds change second by second. Without a battery to absorb and smooth out these massive fluctuations, a direct-connect inverter would constantly turn off and error out.
- Turbine Destruction: When a battery is full or disconnected, a wind turbine loses its "load" (resistance). Without that resistance, the blades can spin out of control in high winds and physically destroy the unit. The charge controller uses the battery connection to safely dump excess power and slow the turbine down.
-
Wiring & Installation Requirement:This wind turbine generates 3-phase AC power andcannotbe connected directly to a battery, solar controller, or home inverter. To operate safely, it must run through a dedicatedWind/Solar Hybrid MPPT Controller with an integrated Dump Load Resistor. The dump load prevents the turbine from over-speeding and destroying itself in high winds once your batteries are fully charged.
-
It is almost always one of three common installation issues. Check them in order:
1. Your multimeter is set to DC (the most common mistake).
- The issue: measuring the three turbine wires with the meter set to DC volts.
- The reality: wind turbines generate 3-phase AC power directly from the stator.
- The fix: switch your multimeter to AC volts (V~). Testing these wires on a DC setting gives a false reading near zero.
2. The turbine is stalling because of a short.
- The issue: the blades turn heavily and slowly, or lock up.
- The reality: if any of the three AC output wires touch each other, or the controller’s internal braking diodes have short-circuited, it acts as a magnetic brake — the turbine can never spin fast enough to build voltage.
- The fix: completely disconnect the turbine from the controller. If it suddenly frees up and spins much faster, the problem is a short in the wiring or a faulty controller.
3. Voltage drop from thin cables.
- The issue: thin wire run a long way from the tower to the battery shed.
- The reality: thin solar or automotive cable over a long run (20 metres or more) loses the power as heat in the wire before it reaches the controller.
- The fix: use heavy cable between the mast and the controller on long runs — minimum 8 AWG, ideally 6 AWG.
-
Because the number on the box is a peak rating, not a promise. A turbine’s rated output is measured at a specific wind speed — for these models that is 13 m/s, about 47 km/h — and most sites see far less most of the time. Your display shows what the wind is delivering right now, so it will sit well below the rated figure and move second by second with the wind. That is physics, not a fault.
Where these turbines earn their keep is time: they keep charging through the night and through weather that shuts solar down. If the display shows 0 W while the blades are spinning, that is a different issue — see the 0 W question below.
-
Not necessarily — this is one of the most common questions we get, and it's rarely a faulty unit. It's usually a quick settings check, or (on a first-time install) how the wiring and start-up sequence were done. See our full Wind Turbine 0W Troubleshooting & Installation Guide for the complete walkthrough, or contact us and we'll help you sort it out.
-
Short answer: wire your bus bar and breakers before and after the controller, then power up in the right order — battery first, then solar, then wind. Getting the sequence right prevents almost all wiring issues, including the common “spinning but 0 W” problem.
Correct installation comes down to isolation and the right sequence:
- Fit a breaker before the controller (turbine/solar side) and after it (battery side), landing on a DC bus bar
- Keep the turbine-to-controller cable run to 2–10 metres to limit voltage drop
- Power up in this order: battery breaker first, then solar, then wind turbine last

66W Super Fast Charge 1-to-3 Power to USB
One socket. Four things that need power.
The ute has one cigarette socket and everything wants it. The fridge is already in there. Then it is the dash cam, the handheld GPS, your phone and whoever is in the passenger seat. Something gets unplugged, and out on a remote track the thing that gets unplugged is usually the phone — which is your map, your camera and your only way of raising anyone. Flat phone, no navigation, no way to raise help, and a small problem turns into a long walk.
This is an OZIO DY48TC. It goes into the one socket you have, hands you a full-size socket back on top for the fridge lead, and adds three USB ports down the front with a voltage readout so you can see what the cranking battery is actually sitting at. The head swivels so your cables are not fouling the gear lever.
The honest part first, because the name on this listing will mislead you otherwise. The 66 W is one port’s headline number, not a total across the unit, and not every phone will ever see it. It is a specific high-current profile. A handset that does not speak that profile drops back to the ordinary fast-charge steps on the same port. The Limits tab spells out exactly what that means for you.
What It Does
- Turns one socket into four: three USB ports on the front and a replacement cigarette socket on top, so the fridge lead keeps its home.
- Charges three at once: the supplier states the three USB ports can be used together. It does not state what the combined output falls to when they are.
- Shows system voltage: an LED readout of what is actually at the socket, so you are not guessing how hard you have flogged the cranking battery.
- Angles to the console: the head swivels 60° left and right on the supplier artwork, which is enough to point cables away from the gear lever.
- Runs on 12 V or 24 V: supplier stated across every listing of this unit, so it suits a ute, a 4x4 and a 24 V truck.
Key Features
- 12 V and 24 V input: the supplier states DC 12 V to 24 V, and its own artwork panel reads universal 12/24 V automotive.
- Keeps your socket: a full-size cigarette socket sits on top, stated by the supplier at 90 W.
- USB-C, marked PD3.0: stated at 20 W, with steps of 5 V/3.4 A, 9 V/2.22 A and 12 V/1.67 A.
- USB-A, marked Super: stated steps of 4.5 V/5 A, 9 V/2 A, 12 V/1.5 A and 11 V/6 A. That last step is where the 66 W figure comes from.
- USB-A, marked 2.4 A: the plain port, moulded 2.4 A on the housing itself.
- Voltage readout: a lit LED display across the front face, visible at a glance from the driver’s seat.
- 130 mm long: 40 mm across the head, per the supplier’s own dimension panel.
- ABS housing: supplier stated, with a bright trim ring that we have not confirmed is metal.
- Protection circuit: over-current, short circuit and over-temperature, all supplier stated with no test data behind them.
Limits
- 66 W is one port: it belongs to the middle USB-A port alone and it needs a handset that supports that exact 11 V/6 A profile, plus a cable rated to carry it. Anything else falls back to the ordinary steps on that port and charges a lot slower. An iPhone will never use it — it takes the USB-C port at 20 W instead.
- Not on both options: the supplier builds this body with more than one port set. The code behind our cheaper option is B, which the supplier lists as PD 20 W + QC3.0 + 2.4 A — no 66 W port at all. The dearer option is code C, which has it. The two options are a different port set, not a different cable.
- No combined figure published: supplier sources quote 90 W, 180 W and 188 W for the same charger. Those are sums of what each port can do on its own, which is not what you get with everything plugged in at once. We are not going to publish a total we cannot stand behind.
- The spare socket is 90 W: that is the supplier’s figure for the socket on top. Check what your fridge, compressor or inverter lead actually draws against it before you rely on it.
- No certificate sighted: supplier listings mention a CE mark. We have not sighted a certificate for any electrical safety or EMC standard, and no Australian approval mark has been sighted either. A mark printed on artwork is not a certificate and we will not publish it as one.
- No fuse rating stated: the supplier does not say what protection is inside the plug barrel. Treat it like any other socket accessory and pull it out when the vehicle is parked up for a long stretch.
- Not a sealed unit: this is a dash accessory. Nothing is stated about dust or moisture ingress, so it does not belong in the spray on an open boat or anywhere it will get wet.
- The display is an indicator: it reads what is at the socket, not a battery state of charge, and the number moves around while the engine is running. It is a useful glance, not a battery monitor.
Q & A
Will my phone actually charge at 66 W?
Almost certainly not. That figure is the top step of one port and it needs a handset built for that exact 11 V/6 A profile, on a cable rated to carry 6 A. Every other phone drops back to the ordinary fast-charge steps on that port. If you are on an iPhone, it will use the USB-C PD port at 20 W no matter which option you pick.
Will it survive in a 24 V truck?
Yes. The supplier states a DC 12 V to 24 V input on every listing of this unit and its own artwork panel says universal 12/24 V automotive. That is a stated figure rather than one we have put on a bench, but it is stated consistently in four separate places.
Can I still run the fridge?
That is the whole point of the socket on top — you do not lose the original one to plug this in. The supplier states 90 W for that socket. Check what your fridge draws against that figure first, because 90 W is not a lot of headroom for anything bigger.
What is the difference between the two options?
The middle USB-A port. The supplier’s code behind the cheaper option is B, which its own listing defines as PD 20 W + QC3.0 + 2.4 A. The dearer one is code C: PD 20 W + 66 W + 2.4 A. The photographs on this page show the code C port set — PD3.0, Super and 2.4 A. The option names on the buy box do not describe that difference, so go by the Specs tab.
Does a cable come with it?
Not stated. The supplier’s product code carries the words “with Type-c”, but nothing in its listing says a cable is in the box and we have not sighted one. Buy on the basis that you are getting the charger only.
Has it been certified for use here?
No certificate has been sighted for any standard. Supplier listings mention a CE mark, and there is no Australian approval mark on anything we have seen. We list what the supplier states and nothing more.
