Wind Turbine FAQs
-
Start with two questions: how much wind does your site actually get, and how much room do you have.
Vertical turbines (X-300, T-500W, and the H12 and HPRO series) start turning in about 2 m/s and take wind from any direction, so they suit rooftops, suburban blocks and anywhere the wind swirls and shifts. They run from 300 W up to 2000 W.
Horizontal turbines (S-400W, M-600W, M-800W, and the L1, L2 and G series) want cleaner, steadier wind and a clear run at it. They scale further — 400 W up to 5000 W — and most of them survive heavier weather.
Match the turbine to your battery bank, not to the biggest number. 12 V suits a camper, 4WD or tinnie; 24 V a van, cabin or boat; 48 V a shed or remote block. The largest models run at 220 V, and the L2-3000, G-3000 and G-5000 are ground-mount only — they need a 10–15 m mast and are not rooftop units.
Rated power is measured at 10–12 m/s. What you get at your place depends on your wind, your mast height and the season — not on a number on our website.

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

G-5000 Horizontal Wind Turbine — 5000 W at 11 m/s, 240 V
The biggest machine we sell, for the site that outgrew everything smaller.
Some sites simply eat power. A farm with pumps and a cool room, a small off-grid plant, a work camp where the generator never gets a day off — the loads run around the clock and every grey week the fuel bill says so. At that scale, a small turbine is a gesture. This is not a gesture.
The G-5000 is the largest unit in our range — 230 kg of die-cast aluminium and steel swinging a 5.4 m three-blade rotor on a dedicated 10–15 m ground mast. It starts turning at 2.5 m/s, begins charging at 3 m/s, and carries the G Type's signature fitting: a mechanical PGJ brake (24 V powered), specified by the manufacturer for harsh, hard-to-service sites. This is not a rooftop unit and never will be.
Straight up about the numbers: the 5000 W rating is measured at 11 m/s — a 40 km/h wind, which is a genuinely windy day. The manufacturer's curve shows 5,300 W at that speed, peaking at 5,400 W at 12 m/s. At a good steady coastal breeze of 7 m/s you will see about 2,150 W — working around the clock. This machine wants a genuinely windy, genuinely open site to be worth the money, and we would rather say that plainly than sell you the headline number.
What It Actually Makes
| Wind speed | Feels like | Output |
|---|---|---|
| 4 m/s (14 km/h) | Light breeze | 380 W |
| 5 m/s (18 km/h) | Flags start to lift | 850 W |
| 6 m/s (22 km/h) | Steady inland breeze | 1,390 W |
| 7 m/s (25 km/h) | Decent coastal day | 2,150 W |
| 8 m/s (29 km/h) | Good working breeze | 3,100 W |
| 9 m/s (32 km/h) | Strong breeze | 4,050 W |
| 10 m/s (36 km/h) | Windy | 4,800 W |
| 11 m/s (39.6 km/h) | Rated wind speed | 5,300 W |
| 12 m/s (43 km/h) | Peak output | 5,400 W |
| 14 m/s (50 km/h) | Near gale | 5,200 W |
| 16 m/s (58 km/h) | Gale — output falls away | 3,800 W |
That is the manufacturer's own measured curve, and we would rather you saw it before you bought. What the 5,000 W in the name means: that is the most this turbine makes, and only in a 40 km/h wind. On a normal breezy day — 7 m/s, about 25 km/h — it makes about 2,150 W. Work out your battery bank and cable from the table above, not from the number in the name.
What It Solves
- The generator that never stops: at farm and small-plant scale, wind is the only renewable that works nights and winters. Every windy hour is diesel not burnt and a service not booked.
- The grey winter week: the fronts that flatten solar for days at a stretch are exactly the weather a 5.4 m rotor works hardest in.
- The big battery bank: a bank sized for a working site needs kilowatts going back in, not a trickle. The matched controller pushes up to a published 105 A into 48 V.
- The remote site: off-grid work environments where a service call is an expedition — which is precisely why the manufacturer fits the serviceable mechanical brake.
- The site that outgrew its system: if the G-3000's numbers still fall short of your loads, this is the top of our range — beyond it, you are into engineered wind projects, and we will say so.
Key Features
- Largest in the range: 5.4 m three-blade rotor, 230 kg net, reinforced FRP blades on a die-cast aluminium and steel body.
- Mechanical PGJ brake: the fitted overspeed brake is the mechanical PGJ unit (24 V powered), confirmed by the manufacturer — specified for harsh, hard-to-service sites.
- Starts early for its size: turning at 2.5 m/s, charging from 3 m/s (10.8 km/h).
- Built to survive 50 m/s: that is 180 km/h. If your site sees worse than that, this is the wrong machine for it and we would rather say so.
- Permanent magnet generator: 3-phase AC synchronous with NdFeB magnets, IP54 protection — no brushes to wear, no exciter current to waste.
- Ground-mast machine, full stop: 10–15 m dedicated mast. Not a rooftop unit — at this weight it has no business on a building.
- Controller with published amps: the matched MWM-series controller is one of the few in the range with a real, manufacturer-printed output current figure — 105 A.
Kit, Or Turbine Only
The kit pairs the turbine with the manufacturer's matched controller: the WW50-48-240, a heavy-duty pure-wind MPPT unit that ships in its own wooden crate with the dump-load box included. It rectifies the turbine's three-phase output and steps it down to charge a 48 V battery bank, with a manual brake button, lightning protection and an LCD display. Pure-wind means exactly that — no PV input at all, and the catalogue lists no wind-solar hybrid option for this turbine. If your plan needs solar on the same controller, this machine does not have that option and we would rather tell you now.
Sourcing your own controller rated for a 5 kW, 220 V machine? Pick Turbine only.
What Else You'll Need
A turbine on a pole is half a system. The other half is a 10–15 m mast in clean air with proper footings, cable sized for the run, breakers and an isolator, a dump load (included with the kit controller) and a battery bank to feed. Cable sizing depends on run length, voltage and current — that is your electrician's call, not a line on a product page. 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 G-5000 you receive is this design, at the sizes in the spec table.
Q & A
Will it really make 5000 watts?
At its rated 11 m/s — a 40 km/h wind — the manufacturer's curve shows 5,300 W, peaking at 5,400 W at 12 m/s. On a typical usable breeze of 5 to 8 m/s you will see roughly 850 to 3,100 W, all day and all night. Work out what you will actually get from the output table above, not from the number in the product name.
Can I run solar panels into the kit controller?
No. The WW50-48-240 is a pure-wind MPPT unit with no PV input at all, and the manufacturer's catalogue lists no wind-solar hybrid controller for this turbine. Solar on the same site needs its own charge controller running alongside — talk to us before you order and we will say plainly whether this machine fits your plan.
What charging current does the kit controller deliver?
This is one of the few controllers in the range with a real published figure: maximum output current 105 A into the 48 V bank, printed by the manufacturer for this exact model. Be careful with the other number on its sheet — the 21 A rated input current sits on the 280 V DC side of the converter, and input and output currents must never be mixed up. Cable and breaker sizing at 105 A is serious business and strictly your electrician's job.
Is the cable from the turbine AC or DC?
AC. The turbine generates 3-phase AC at a nominal 220 V, rising to 242 V maximum, and the controller rectifies it to DC before stepping it down to charge the battery. A generator is not a battery: the voltage on that cable rises with rotor speed, which is exactly why the matched controller accepts 60 to 320 V DC on its wind side. Cable selection and protection at these voltages are strictly your electrician's job.
Why does a 220 V turbine charge a 48 V battery bank?
Because the matched controller is a step-down MPPT: high voltage from the turbine side is converted down to battery voltage, which keeps the current in the long mast cable low. On paper the pairing lines up — the turbine tops out at 242 V and the controller's wind side is rated 280 V DC — and it is the manufacturer's own catalogue pairing. We have still asked the factory to confirm the combination in writing, because their page prints the two voltages side by side without explaining it. When their answer lands, it goes here.
Can I mount it on the roof?
No. The manufacturer specifies a dedicated ground mast of 10 to 15 m, and nothing else. A 230 kg machine with a 5.4 m rotor has no business on a building — if a rooftop turbine is what your site needs, look at the smaller horizontals in our range instead.
What happens to it in a storm?
The mechanical PGJ brake handles overspeed, the controller adds over-current protection with its dump load, and the machine is built to survive 50 m/s (180 km/h). If your site regularly sees more than that, do not put this turbine on it.
What is the warranty position?
Twelve months. Professional installation by a licensed electrician is a condition of it — keep the electrician's invoice with your paperwork. 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.
How long until it arrives?
Built to order and sea-freighted — allow 6 to 8 weeks. Freight is quoted per order — this is a sea-freight machine and the cost depends on your delivery address. Email us before you order and we will confirm it. The turbine arrives as two packages — a nacelle crate and a 2.74 m blade-and-mast crate, 265 kg gross between them — so plan for machinery assistance at your end, not a hand unload. The kit adds the controller's own wooden crate (46.5 kg) with the dump-load box inside.
