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

Wireless Anemometer Weather Station
Real wind numbers, not a guess off the trees.
You can stand in the yard, watch the trees move and call it a bit breezy. That guess is worth nothing when you are working out where a turbine goes, whether the awning stays out overnight, or whether the crew keeps working. Wind is the one thing on a site that changes hour to hour, and it is the one thing almost nobody actually logs.
This is a two-piece station. A sensor head lives outside on a mast — a three-cup anemometer for speed, a vane for direction, and a louvred shield below them holding the temperature and humidity sensor out of direct sun. It sends its readings back to a small LCD receiver you keep inside, over a 433 MHz radio link. No cable to run between them, and nothing that touches the internet.
Be clear about what it is: a wind and air station, not a full meteorological set-up. The screen carries wind speed, wind direction, outdoor temperature and humidity, indoor temperature and humidity, and the time and date. There is no rain gauge on it and no barometer in it.
And the part a turbine buyer needs said plainly: the supplier prints no wind speed range and no accuracy figure on this product’s own artwork. We are not going to invent one. What we can tell you is what the display shows, how the link works and how it mounts — everything we could not source is marked “Not specified by supplier” in the Specs tab, and there are a lot of those rows.
What It Does
- Wind speed: shown on the receiver in km/h, with the reading sitting inside the compass rose.
- Wind direction: a compass rose with the eight points labelled — N, NE, E, SE, S, SW, W and NW — and a pointer that swings to the wind.
- Outdoor temperature: read from the sensor inside the louvred shield on the mast, in °C.
- Outdoor humidity: relative humidity from the same outdoor sensor, shown as %RH.
- Indoor temperature and humidity: the receiver reads its own room as well, so inside and outside sit on the screen together.
- Time, day and date: a clock line across the top, with an alarm indicator on the screen.
- Recall of recorded readings: the receiver carries buttons for stored values — one pictured unit is marked MAX-MIN and CLEAR, the other HISTORY.
Key Features
- Cup and vane head: three-cup anemometer for speed and a separate tail vane for direction, the standard arrangement rather than a single moving part doing both jobs.
- Louvred radiation shield: the temperature and humidity sensor sits inside a stacked louvre stack, so direct sun does not cook the outdoor reading.
- 433 MHz radio link: sensor to display over 433 MHz, printed on the supplier’s own artwork.
- No app, no account: nothing in the supplier material shows a phone app, a Wi-Fi setup or a cloud service. The readings go to the display in front of you and stop there.
- Metric or imperial on the screen: the display switches between °C and °F, and between km/h and mph. Every figure BushLine publishes is metric.
- Mast with a base plate: the sensor pole ends in a square base plate with fixing holes, and carries a clamp bracket on the shaft.
- Desk or wall receiver: a keyhole slot is moulded into the back of the display and a stand folds out of it.
- Battery powered at both ends: no mains lead runs to the mast and there is no solar panel on the sensor.
- Separate indoor channel: the receiver has its own temperature and humidity sensor, so you are comparing the shed to the outside, not guessing.
Limits
This is the honest list. Most of it is what the supplier does not state, and on a wind instrument that matters more than usual.
- No stated wind speed range: the supplier prints no minimum, no maximum and no start-up wind speed on this product. If you need a known measuring range, this is not the instrument to buy on trust.
- No stated accuracy: no accuracy figure is given for wind speed, temperature or humidity, and no calibration certificate comes with it. Treat it as an indication of conditions, not a reference measurement.
- No stated radio range: 433 MHz is short-range radio. The supplier does not state how far, and walls, sheds, steel and distance all cut it down.
- No rainfall: there is no rain gauge, no funnel and no tipping bucket. It does not measure rain.
- No air pressure: there is no barometer in it. Nothing on this unit forecasts or predicts weather — it reports what is happening now and what it has recorded, and that is all.
- It will not tell you turbine output: a wind reading is not a power figure. What a turbine makes from a given wind depends on the machine, the tower height, what is upwind of you and your battery bank. We publish no yield estimate off this device and you should not calculate one either.
- No weather rating printed: the sensor head is clearly built to live outdoors, but no IP rating and no water resistance figure appears on it or in the supplier data. We are not going to call it weatherproof to a number nobody has stated.
- The display is an indoor unit: it has a fold-out desk stand and a wall keyhole. It is not built to sit out in the weather.
- Two receiver layouts pictured: the supplier images show two different button sets on the display — MODE / NEXT / SET / HISTORY on one, MODE / SET / C-F / CH / CLEAR / MAX-MIN on the other. We cannot tell you which one arrives.
- Fixings are not listed: the supplier does not state what mounting hardware, mast or fasteners are in the box. Assume you are finding your own pole and bolts.
- Batteries are not stated: the type, the number and the expected life are all absent from the supplier data, at both ends.
Q & A
Will this tell me whether my block is any good for a wind turbine?
It will give you a running read of wind speed and direction at the height you mount it, which is the raw information you need and which most people never actually collect. What it will not do is tell you what a turbine will produce there — that depends on the machine, the tower height, the terrain upwind and your battery setup. Use it to find out whether the wind is genuinely there before you spend on a turbine, not to work out watts.
Does it need Wi-Fi, an app or an account?
No. The sensor talks to the display over a 433 MHz radio link, which is the frequency printed on the supplier artwork. Nothing in the supplier material shows a phone app, a login or a cloud service. The flip side is that there is no logging to your phone and no remote access — what you get is what is on the screen in front of you.
How far can the outdoor sensor sit from the display?
The supplier states no range on this product, so we will not quote one. 433 MHz is short-range radio: expect it to work across a house or a yard and expect walls, a steel shed or a long run to cut it back. Mount the display where the signal holds and be prepared to move it.
Can I read everything in metric?
Yes. The display shows °C and km/h, and one of the pictured receivers has a dedicated C-F button to switch units. It can show °F and mph if you want it that way, but it does not have to.
Does it measure rainfall or air pressure?
No to both. The screen carries wind speed, wind direction, outdoor temperature and humidity, indoor temperature and humidity, and the time and date. There is no rain gauge and no barometer, so despite the name it is a wind and air station rather than a full weather station.
Can I leave the sensor outside permanently?
That is what it is shaped for — cup anemometer, tail vane and a louvred shield on a mast with a base plate. But no IP rating or water resistance figure is printed on it or stated by the supplier, so we cannot tell you how it copes with driving rain, dust or salt air. Mount it where you can get it down again if you need to.
