Wind Turbine FAQs

  • 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:

    1. Wind Turbine: Generates wild, fluctuating 3-phase AC power as wind speeds change.
    2. 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.
    3. 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.
    4. 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

Find out if you have the wind, before you buy the turbine.

Everyone thinks their place is windy. Standing on a ridge with your hat coming off feels like proof. It isn't — a turbine runs on the average across a week, not the gust that got your attention, and the difference between those two numbers is what decides how well a turbine performs for you.

This is a cup anemometer that talks to your phone. Peg it where the turbine would go, leave it, and read the actual numbers: current, maximum, minimum and average wind speed, logged to an app so you have a record instead of an impression.

It is also a pocket weather station — barometric pressure, altitude, temperature, humidity, dew point and wind chill. Useful for long-range shooting, for knowing what is coming at a remote camp, and for working out why the turbine had a quiet week.

What it will not do: it will not tell you which turbine to buy, and one afternoon of readings proves nothing. Wind varies by season. Leave it running across a few weeks in different conditions before you make a decision on the strength of it.

What It Solves
  • Size the turbine to the site: check your measured average against the cut-in speed listed in the turbine's specification table, so you choose the right model first time.
  • Pick the right spot on the block: move it around over a few days. Ten metres and a bit of height often separate a good position from a sheltered one, and the shed roof is rarely the answer.
  • Work out a quiet week: when output drops, the first question is always whether it was the wind or the gear. Logged data answers it without pulling anything apart.
  • Call the weather at camp: a falling barometer and a shifting wind give you an hour or two of warning to get the awning down.
  • Long-range shooting: wind speed, altitude, pressure and temperature are the four numbers a ballistic solver wants, and this reads all of them.
Key Features
  • Omnidirectional cup head: registers wind from any angle, so it does not need aiming into the breeze like a fan-style meter.
  • Reads 0.7 to 42 m/s: that is 2.5 to 151 km/h, or 1.4 to 81.6 knots.
  • Current, max, min and average: the average is the number that matters for siting a turbine.
  • Bluetooth to your phone: live readings and logging through the app, so you keep a record rather than a memory.
  • Six more measurements: atmospheric pressure, altitude, temperature, humidity, dew point and wind chill.
  • Backlit LCD: readable at dusk without getting the phone out.
  • 150 grams with batteries in: light enough to live in a pack or a glovebox permanently.
  • Runs on 2 x AAA: standard cells, with a low battery indicator and auto or manual shutdown.
What Else You'll Need

Once you know what your site does, these are the parts that go with a turbine:

  • A turbine matched to your wind: the vertical axis wind turbine range lists a cut-in speed on every spec table. Compare it against the average you measured and pick accordingly.
  • A hybrid controller: a turbine cannot charge a battery bank on its own. The wind and solar hybrid controllers handle the wild AC coming down the pole and give the turbine somewhere to dump surplus.
  • Breakers, bus bars and cable: 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. The electrical supplies range covers it.

Q & A

How long should I leave it running before I trust the numbers?
Longer than feels necessary. Wind is seasonal, and a single still week or one windy afternoon will both mislead you. Take readings across several weeks and in different conditions. If you are deciding on a purchase worth thousands, a month of data is cheap.

Where should I put it to get a useful reading?
As close as you can to where the turbine head would actually sit — same spot, same height if you can manage it. Wind speed changes a lot with height and with anything upwind of it. A reading taken at head height next to a shed will not match a turbine on a pole in the open.

Will it tell me how much power a turbine would make?
No, and be wary of anything that claims it will. It gives you wind speed. You then compare that against the power curve and cut-in speed on the turbine's own specification table. Those two numbers together give you a realistic idea; the anemometer alone does not.

Does it need the phone to work?
No. It reads on its own backlit LCD. The Bluetooth app adds logging and history, which is the part that makes it useful for siting a turbine rather than just checking the breeze.

Is it waterproof?
Not specified by supplier. No IP rating is given, so treat it as a shower-and-retrieve instrument rather than something to leave pegged out through a storm.

What is the accuracy?
Temperature is stated at ±2°C. A wind speed accuracy figure is not specified by supplier. For siting a turbine that is generally fine, because you are looking at averages and trends rather than a certified measurement.

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
