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

M-600W Horizontal Wind Turbine 24/48V
The cabin battery's night shift.
An off-grid cabin runs on sunlight and arithmetic. The panels fill the bank by mid-afternoon, and from then on everything — fridge, pump, lights, chargers — is spending. In summer the sums work. In winter, with short days and a week of cloud, they stop working, and the generator ends up doing the night shift.
The M4-600 is the step up from a caravan-sized turbine: a 1.85 m three-blade rotor on a 20 kg machine, rated 600 W. It starts turning at 2 m/s and begins charging at 3 m/s, and it works when the panels cannot — through the night, and through exactly the windy grey systems that flatten solar for days.
Straight up about the numbers: the 600 W rating is measured at 12 m/s — a 43 km/h wind. On a decent 7 m/s breeze you will see about 230 W, running around the clock. That is the honest arithmetic, and it is still a lot of amp hours by morning.
What It Actually Makes
| Wind speed | Feels like | Output |
|---|---|---|
| 4 m/s (14 km/h) | Light breeze | 35 W |
| 5 m/s (18 km/h) | Flags start to lift | 85 W |
| 6 m/s (22 km/h) | Steady inland breeze | 153 W |
| 7 m/s (25 km/h) | Decent coastal day | 231 W |
| 8 m/s (29 km/h) | Good working breeze | 323 W |
| 9 m/s (32 km/h) | Strong breeze | 430 W |
| 10 m/s (36 km/h) | Windy | 538 W |
| 11 m/s (40 km/h) | Very windy | 600 W |
| 12 m/s (43 km/h) | Rated wind speed | 620 W |
| 13 m/s (47 km/h) | Peak output | 625 W |
That is the manufacturer's own measured curve. At a steady 7 m/s this turbine makes about 231 W — not 600 W — and we would rather you knew that before you bought it.
What It Solves
- The winter deficit: short days and long nights flip the cabin's energy budget negative. Wind keeps depositing while the panels are dark.
- The week of grey: a slow front can sit on your solar for days — and blow the whole time. This is the machine for that week.
- The hobby farm shed: pressure pump, tools, a fridge and lighting on a bank that has to survive the weekend you are not there.
- The telecom hut problem: repeaters and monitoring gear draw day and night; a 24-hour source suits a 24-hour load.
- Less generator time: every windy night is diesel not burnt and a service pushed further out.
Key Features
- 600 W rated at 12 m/s, peaking at 625 W — with the full measured curve published above.
- 24V or 48V: 48V halves the current of 24V for the same power, so longer cable runs get cheaper.
- 1.85 m three-blade rotor: reinforced nylon-fibre blades, 900 mm each, on a die-cast aluminium body.
- Starts early: turning at 2 m/s, charging from 3 m/s (11 km/h).
- Built to survive 50 m/s: 180 km/h — genuine cyclone-belt figures. If your site sees worse, tell us and we will say so.
- Permanent magnet generator: 3-phase AC synchronous, NdFeB magnets, IP54, auto yaw into the wind.
- Two layers of protection: electromagnetic brake for overspeed, controller over-current protection plus dump load for overload.
- Two controller choices: the HECR wind-solar hybrid (runs panels too) or the pure-wind WCMD MPPT — pick either as a kit, or take the turbine only.
Kit, Or Turbine Only
The kit pairs the turbine with the manufacturer's matched hybrid controller for your voltage — LHECR0824 on 24V, LHECR1248 on 48V — plus the dump-load resistor. The hybrid part matters: the same box takes a solar array on a PWM input (up to 1000 W of PV on the 24V unit, 1200 W on the 48V), so one controller runs the turbine and the panels together. Never going to run solar? Pick With Pure-Wind Controller for the manufacturer's pure-wind WCMD unit instead — LWCMD800W-24V on 24V, LWCMD800W-48V on 48V, no PV input at all. Already sorted for control? Pick Turbine only.
What Else You'll Need
A mast in clean air, cable sized for the run, breakers and an isolator, and a battery bank to feed. Cable sizing depends on run length, voltage and current — that is your electrician's call. Browse bus bars, breakers and wiring in the Electrical Supplies collection, and the full controller range here.
Representative photos: the manufacturer supplies one set of photographs per turbine family, not per model. The M4-600 you receive is this design, at the sizes in the spec table.
Limits
It is not 24/7 power. It makes power when the wind blows and none when it drops. Pair it with solar and a properly sized bank; do not plan a household around the rated wattage.
The rated figure needs a 43 km/h wind. Most sites, most of the time, will see a fraction of 600 W. The output table on this page is the honest planning number.
We stock the 3-blade version only — 1.85 m rotor, 900 mm blades, confirmed by the manufacturer. If you have seen a 5-blade M4-600 elsewhere, that is a different build we do not sell.
No charging current in amps is published for the matched controllers, and we will not invent one by dividing watts by volts. Do not size cable or breakers from the wattage in any product title.
No certification claim. We have sighted no certificate that names this model, so we make no CE or RCM claim for it.
It is not plug-and-play. Professional installation by a licensed electrician is a warranty condition — keep the invoice. And be aware the manufacturer treats blade damage from consistently extreme wind, and motor burnout after prolonged high-speed running, as case-by-case assessments rather than automatic cover.
Q & A
Will it really make 600 watts?
In a 43 km/h wind, yes — the measured curve crosses 600 W at about 11 m/s and peaks at 625 W. On a typical usable breeze of 5 to 8 m/s you will see roughly 85 to 320 W, day and night. Plan off the table above, not the title.
Does the kit controller take solar panels?
Yes. The HECR series is a wind-solar hybrid: wind charges through MPPT and a solar array connects to the same unit on PWM — up to 1000 W of PV on the 24V model, 1200 W on the 48V. Never running panels? Pick With Pure-Wind Controller — the WCMD unit has no PV input at all.
Is the cable from the turbine AC or DC?
AC. The turbine generates 3-phase AC; the rectifier inside the controller converts it to DC, and the DC charges the battery. The voltage on the tower cable rises with rotor speed — which is why the controller is built to take far more than the nominal battery voltage on its input. Cable selection and protection are your electrician's job.
24V or 48V — which should I run?
Match the battery bank you already have. Starting fresh with a longer cable run, 48V moves the same power at half the current of 24V, which means thinner, cheaper cable and less loss. There is no 12V version of this turbine.
Can I mount it on the roof?
Yes — 3 to 6 m above the roofline, or 6 to 10 m on a ground mast. Clean air is output: every metre above the turbulence pays for itself.
What happens to it in a storm?
The electromagnetic brake and the controller's overspeed protection wind it back, and the machine is built to survive 50 m/s (180 km/h). If your site regularly sees more than that, this is the wrong machine for it.
How long until it arrives?
Built to order — allow 6 to 8 weeks. Delivery is free to Australia and New Zealand. The kit arrives as separate boxes: the turbine, and the controller with its dump load.
