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

L1-1000 Horizontal Wind Turbine — 1000 W at 11 m/s, 48 V
Half your power problem happens after dark.
An off-grid house bank does its hardest work when the panels are asleep. The fridge, the freezer, the water pump and the lights all keep drawing through the night, and a grey winter front can flatten solar output for a week at a stretch. That is when the generator hours pile up — and the fuel runs with them.
The L1-1000 is the smallest turbine in our L-series — a 48 kg machine with a 2.6 m three-blade rotor, built for a 48 V battery bank. It starts turning in a 2 m/s breath of wind and begins charging at 3 m/s. It works the hours and the weather that panels cannot: night, winter, and the windy fronts that kill solar for days.
Straight up about the numbers: the 1000 W rating is measured at 11 m/s — a genuinely windy 40 km/h day, not a normal afternoon. On a decent coastal breeze you will see a few hundred watts, working around the clock. Think of it as a second charging source that carries the bank through the hours solar cannot, not a replacement for your panels.
What It Actually Makes
| Wind speed | Feels like | Output |
|---|---|---|
| 3 m/s (10.8 km/h) | Leaves stirring | 5 W |
| 4 m/s (14 km/h) | Light breeze | 55 W |
| 5 m/s (18 km/h) | Flags start to lift | 130 W |
| 6 m/s (22 km/h) | Steady inland breeze | 230 W |
| 7 m/s (25 km/h) | Decent coastal day | 350 W |
| 8 m/s (29 km/h) | Good working breeze | 490 W |
| 9 m/s (32 km/h) | Strong breeze | 650 W |
| 10 m/s (36 km/h) | Windy | 840 W |
| 11 m/s (39.6 km/h) | Rated wind speed | 1,005 W |
| 12 m/s (43 km/h) | Peak output | 1,040 W |
| 14 m/s (50 km/h) | Near gale | 1,000 W |
| 16 m/s (58 km/h) | Gale — output falls away | 700 W |
That is the manufacturer's own measured curve, and we would rather you saw it before you bought. What the 1000 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 350 W. Work out your battery bank and cable from the table above, not from the number in the name.
What It Solves
- The overnight drain: the fridge, freezer and pumps pull on the house bank all night while the panels do nothing. A breeze feeds the bank the whole time you are asleep.
- The grey winter week: the fronts that flatten your solar for days are exactly the weather this machine works hardest in.
- The solar-only system that almost copes: a second charging source that peaks in the weather solar hates means a smaller battery bank doing the same job.
- The site a long way from the grid: farm sheds, telecom sites and cabins running a 48 V bank where every delivered litre of generator fuel costs real money.
- Less generator time: every hour of breeze is fuel you have not hauled and a service you have not done.
Key Features
- Household scale: the entry point to the L-series — 1 kW rated, 48 kg net, built for a 48 V bank.
- Starts early: turning at 2 m/s, charging from 3 m/s (11 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.
- Three-blade rotor, 2.6 m: reinforced FRP blades on a reinforced die-cast aluminium body, IP54 generator.
- Permanent magnet generator: 3-phase AC synchronous with NdFeB magnets — no brushes to wear, no exciter current to waste.
- Two layers of protection: electromagnetic brake for overspeed, controller over-current protection plus dump load for overload.
- Kit option: the manufacturer's matched pure-wind MPPT controller with the dump-load resistor included — or take the turbine only.
Kit, Or Turbine Only
The kit pairs the turbine with the manufacturer's matched pure-wind controller for a 48 V bank — the LWCMD1000W-48V, a wind-only MPPT unit with a built-in LCD and the dump-load resistor included. Be clear on one thing before you order: it has no solar input at all. It runs the turbine, nothing else.
Want one controller running both wind and solar? The manufacturer recommends its HCM hybrid series for the L1 range, but it has not confirmed in writing which HCM model matches this turbine — and we will not sell a pairing we cannot verify. If a hybrid setup is what you are planning, contact us first and we will confirm the matched unit with the manufacturer before you commit.
Already have a controller rated for this turbine? Pick Turbine only.
What Else You'll Need
A turbine on a pole is half a system. The other half is a mast in clean air, 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 L1-1000 you receive is this design, at the sizes in the spec table.
Q & A
Will it really make 1000 watts?
At 11 m/s — a genuinely windy 40 km/h day — yes, and the manufacturer's curve shows it. On a typical usable breeze of 5 to 8 m/s you will see roughly 130 to 490 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 LWCMD1000W-48V is a pure-wind MPPT unit — it has no PV input at all. The manufacturer recommends its HCM wind-solar hybrid series for the L1 range but has not confirmed which model pairs with this turbine, so we do not sell that pairing yet. If you want wind and solar on one controller, talk to us before you order.
Why don't you publish a charging current in amps?
Because the supplier has not published one, and we will not calculate one by dividing watts by volts — that is how people end up sizing breakers off a guess. Do not size cable or breakers from the wattage in any product title. When the manufacturer gives us the amp figure, it goes in the table.
Is the cable from the turbine AC or DC?
AC. The turbine generates 3-phase AC, and the rectifier inside the controller converts it to DC 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 is rated to take up to 180 V on its wind input — far more than the nominal 48 V. Cable selection and protection are your electrician's job.
Can I mount it on the roof?
Yes — 3 to 6 m above the roofline, or 6 to 10 m on a ground mast. Remember this is a 48 kg machine with a 2.6 m rotor: the mounting structure is an engineering job, not an afterthought. Height is output — turbulence near buildings eats the wind before the blades see it, so the extra metres of clean air pay for themselves.
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, 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. Delivery is free to Australia and New Zealand. The turbine arrives as two boxes; the kit adds the controller with its dump-load resistor.
