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 or 20kW 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 catalog are categorized 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.
-
Yes.These turbines have an incredibly low startup wind speed of just 2.0 m/s, meaning the blades will begin rotating in a very gentle breeze. However, please note that physical power generation only starts accumulating once wind speeds consistently clear 4 to 5 m/s.
-
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 caused by one of three common installation errors. Check these variables in order: Checking the Multi-Meter Setting (Most Common Mistake)
- The Issue: The customer is likely measuring the three wires coming out of the turbine using a DC voltage setting on their multimeter.
- The Reality: Wind turbines generate 3-Phase AC power directly from the stator.
- The Fix: Instruct them to switch their multi-meter to AC Voltage (V~). Testing the wires under a DC setting will provide a false, completely inaccurate reading near zero.
2. The Turbine is Stalling Due to Incorrect Wiring
- The Issue: The turbine blades are spinning heavily but turning very slowly or locking up because of an electrical short.
- The Reality: If any of the three AC output wires are accidentally touching each other, or if the controller's internal braking diodes have short-circuited, it creates a magnetic brake. This bogs down the turbine, physically stopping it from spinning fast enough to build voltage.
- The Fix: Have them completely disconnect the turbine from the controller. If the turbine suddenly unbogs and spins much faster when disconnected, the problem is a short circuit in the wiring or a faulty controller.
3. Voltage Drop Caused by Thin Cables
- The Issue: The customer ran thin wiring over a long distance from the tower down to the battery shed.
- The Reality: If they used standard thin solar cables or thin automotive wire over a long distance (e.g., 20+ metres), the natural resistance of the copper wire will choke out the electricity. The energy is lost as heat inside the wire before it ever reaches the meter.
- The Fix: Ensure they are using heavy-duty, minimum 8 AWG or 6 AWG thick cable lines between the mast and the controller house
-
Wind turbines are rated byCumulative Daily Capacity, not instantaneous hourly peak output. Because wind speeds fluctuate constantly second-by-second, a 1200W turbine is designed to yield up to 1200W of total poweraccumulated over a 24-hour periodin optimal conditions (averaging roughly 50W per hour). This constant, steady trickle is exactly what makes vertical turbines perfect for maintaining batteries overnight when solar panels are offline.
-
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 this sequence right prevents almost all wiring issues, including the common "spinning but 0W" problem. Answer (rich text field, with the link placeholder): 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 See our full How to Install & Start Up guide for the complete step-by-step walkthrough and wiring diagram.

- Tracking: You will get a Shipping Confirmation email with your tracking number as soon as your order ships.
If Your Order Is Running Late
Ring 0400 333 898 or email Support@BushLine.com.au and we will chase the tracking ourselves rather than sending you off to do it. You will get a straight answer on where it is, including if it has not moved.
Need A Large Turbine Sooner?
Expedited freight is available on the big units at extra cost, which brings delivery down to roughly a fortnight. It is quoted per order because it depends on the size of the unit and where it is going. Get in touch before you order and we will price it for you.
Your turbine can spin fine on two phases.
A vertical axis turbine sends three-phase AC down the tower on its U, V and W leads, and it only becomes DC once the controller rectifies it. Lose one of those three phases — a failed winding, a corroded joint in the slip ring, a conductor chafed through inside the tower drop — and the turbine keeps turning exactly as it always did. From the ground nothing looks wrong. What actually happens is that charge quietly falls away, week after week, and the first you know about it is the bank going flat during a still spell when you were counting on what the turbine put in earlier.
This is an AC meter for the turbine side of the system. It clips onto the DIN rail in the enclosure between the tower and the controller and reads the three phases coming down, so you can see whether all three are actually generating instead of assuming it. The supplier lists a measuring voltage range of 80–500V at 50–60Hz and a current display range of 0–100A, which is the wild, unregulated output range a vertical axis wind turbine actually produces before anything downstream tidies it up. It also tells you what the turbine is really making in a given wind, which is the number most people want and almost nobody has.
Three things to know before you order. It reads AC only, so it goes on the turbine side — wire it to the DC output of your controller and you will get nothing, and that is the meter working correctly, not a fault. It is IP20, which is finger protection and no water rating at all, so it must live inside an enclosure — worth thinking about, because the AC side is often terminated at the base of the tower. And the supplier gives 0–100A as a display range without ever stating a CT ratio, so whether that 0–100A is measured directly through the meter or through current transformers is not confirmed. On a turbine drop that difference matters. If it is the deciding factor for you, email us before ordering and we will get it in writing rather than guess at it here.
What It Solves
- The silent dead phase: the turbine still spins and looks normal, but one phase has dropped and you are charging on two.
- Turbine or controller?: the bank isn't charging and you need to know which side of the rectifier the fault is on before you climb anything.
- What it makes in real wind: a readout at the tower base so you can match actual output against the wind you are standing in.
- Remote station or bore site: a turbine running unattended for months, where slow output loss goes unnoticed until the batteries are down.
- Shack, hut or off-grid cabin: you visit every few weeks and want a permanent readout instead of pulling a clamp meter out of the ute each time.
Key Features
- Three-phase AC measurement: reads the U, V and W legs coming off the turbine, before the controller rectifies them to DC.
- 80–500V measuring range: covers the swing a turbine puts out between light air and a good blow, at 50–60Hz.
- Current display range: supplier lists 0–100A on the display, with no CT ratio and no direct-measure input rating given — read the Specs tab before you order.
- LED digital display: lit readout you can take in from a step back, with no backlight to wake up and no menu to navigate.
- 35mm DIN rail mount: clips onto standard top-hat rail, taking one 18mm module of width beside your breakers and isolators.
- IP20 protection: finger protection only, no water or dust rating, so it belongs inside a sealed enclosure and out of the weather.
- Temperature range: -5°C to +40°C stated by the supplier — outside that band nothing is guaranteed.
- Low input burden: input circuit power consumption under 2VA, so it takes next to nothing out of what the turbine is making.
- No separate battery: supplier states the meter needs no battery of its own.
- One unit per pack: 0.167 kg, packed at 10 x 8 x 5 cm. Meter only — no current transformers, leads or enclosure.
Where This Fits
This is one part of the gear that sits between a wind turbine and your battery bank. Here's the whole picture:
- Wind turbines: vertical axis turbines from 1kW to 20kW — quiet enough to put near the house, and they charge overnight when your solar can't.
- Hybrid MPPT controllers: you can't wire a turbine straight to a battery. The controller rectifies the output, manages the charge, and brakes the turbine when the bank is full.
- The rest of the electrical range: bus bars, breakers, isolators, cable, lugs and Anderson plugs.
Every input and output wants a breaker or isolator on it, so you can safely shut down and isolate the turbine before you touch anything. That protects you, and it stops a surge damaging your new turbine or the rest of your power system. Cable sizing depends on your run length, voltage and current — if you're building 12V or 24V, check the sizing against your own run or ask your sparky.
Q & A
Where in the system does this actually go?
On the turbine side of your controller, reading the three AC phases coming down the tower. That is what the 80–500V range and the 50–60Hz frequency figure describe. It goes in an enclosure between the tower drop and the controller input, which on most installs means the box at the base of the tower or on the shed wall where those three leads land.
Will it read my battery bank or the DC side of the controller?
No, and it isn't meant to. This is an AC meter. Once your hybrid MPPT controller has rectified the turbine output there is no AC left for it to measure, so on the DC side it will show you nothing. If you want current monitoring on the bank itself that is a different instrument — email us and we'll point you at it.
How would I know a phase has dropped out?
You compare the three phases against each other while the turbine is turning. If one leg is reading well under the other two, or nothing at all, you have a problem up the tower — a winding, a slip ring joint or a damaged conductor in the drop. The turbine will keep spinning either way, which is exactly why you can't tell from the ground without a meter on the AC side.
What current range does it actually measure?
We can't tell you honestly, and we're not going to make it up. The supplier lists a 0–100A display range but has never stated whether that is measured directly through the meter or through current transformers, and no CT ratio is published anywhere in their data. On a turbine drop that decides whether you can wire it inline or need CTs, so if it matters to your install, email us before ordering and we'll get it in writing from the supplier.
Can I mount it outside at the base of the tower?
Not on its own. IP20 means finger protection against a probe of 12.5mm or larger and no protection against water at all. It needs to sit on a rail inside a sealed enclosure, away from rain, hose-down and condensation. Plenty of turbine installs terminate outdoors, so budget for a proper weatherproof box if you haven't got one.
Does it need its own power supply?
The supplier states no separate battery is required. They have not given a clean, single figure for the supply voltage it wants — their own documentation is inconsistent on this — so have your sparky confirm the supply arrangement against the unit in front of them before wiring it in.
Is it certified for Australian installation work?
No certification is stated by the supplier, so we're not claiming one. Wiring on the AC side of a turbine is licensed electrical work in Australia regardless of who owns the turbine — that's a job for your sparky, not a weekend project.
