Wind Turbine FAQs

- Start with two questions: how much wind your site actually gets, and how much room you have.
- Vertical turbines (the X-300, H1000 and H2000) start turning at 2 to 2.5 m/s and take wind from any direction, so they keep working where the wind swirls and shifts — around buildings, trees and rooflines. They run from 300 W up to 2000 W.
- Horizontal turbines (M-400, M-600, M-800, and the L1, L2 and G series) want cleaner, steadier wind and a clear run at it. In clean, steady wind a horizontal of the same rating is usually the better harvester, and they scale further — 400 W up to 5000 W.
- 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.
1. The largest models run at mains voltage, 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.
2. Rated power is measured at 10–14 m/s, depending on the model. What you get at your place depends on your wind, your mast height and the season — not on a number on our website.
1. No. Wind turbines generate "wild" 3-phase AC power that changes voltage constantly with the wind speed.
2. Connecting it directly to a battery or a standard solar inverter will destroy your equipment.
- You must wire the turbine into a dedicated wind charge controller (pure-wind or wind-solar hybrid) with a dump-load resistor.
- The controller converts the power to stable DC to charge your batteries safely.
Match the turbine and its controller to the voltage of your existing battery bank:
- 12 V: compact mobile setups — caravans, 4WDs and camper trailers.
- 24 V: medium setups — off-grid sheds, cabins and motorhomes.
- 48 V: most of this range, and the sensible choice for a full off-grid system. Higher voltage means less current in the cable, so less loss over a long run and lighter cable.
- When your battery bank is fully charged it stops accepting power.
1. If a storm hits at night with the batteries full, a turbine with nowhere to send its power will free-spin out of control and can physically fly apart.
- The controller prevents that by diverting the excess into the dump load resistor, which burns it off safely as heat and acts as an electronic brake to slow the turbine down.
- Yes, you need one.
- Usually quieter, but not silent — no turbine is.
- Why a Horizontal is Louder: its blade tips travel several times faster than the wind, and blade noise climbs steeply with tip speed. The whoosh rises and falls as each blade comes round — a rhythmic swish that carries through wind noise more than a steady hiss does.
- Why a Vertical is Usually Quieter: its blades turn more slowly, so there is less of that whoosh.
1. What we won't Tell you: that it's silent. Every turbine gets louder as the wind picks up. The wind often covers much of it in a strong blow, but a close neighbour can still hear one in light to moderate wind.
2. The manufacturer publishes no noise figure for the turbines themselves (the "65 dB or less" on some Specs tabs is the controller's), so we don't quote one.
- On a building, use vibration isolators — a turbine bolted to a structure carries its sound into the rooms — and check your council's rules on noise, height and placement before you order a mast.
- It will turn, but turning is not charging. The blades start turning at 2 to 2.5 m/s (about 7 to 9 km/h) — a light breeze.
- Charging starts at the cut-in speed: 3 m/s (about 11 km/h) on every model except the X-300, which starts and charges from 2 m/s. Output then climbs steeply with wind speed.
1. The rated figure is measured much higher — 10 to 14 m/s depending on the model, a 36 to 50 km/h wind, not a normal afternoon. Each product page's spec table gives that model's own numbers.
- A gentle breeze keeps the turbine ticking over; it takes real wind to push real power into your batteries. Every horizontal model has its measured power curve published on its product page — work from that, not from the number in the product name.
- No — small turbines are built to spin fast. The smaller the rotor, the faster it has to turn to keep its blade tips up with the wind: the M-400's 1.35 m rotor runs at about 800 rpm, the M-600 and M-800 at about 500, the big G-series at 300.
- In the manufacturer's words, the high rpm is a design necessity, not a defect. A slower generator would need a bigger stator and more magnets and copper — heavier and dearer.
- They start turning at 2 to 2.5 m/s and make power right across the wind range — just less when the wind is light. What you get depends on your site and how high you mount it.
- Yes — connect the turbine to a battery bank first, through a dedicated charge controller.
1. Never straight to an inverter. Connecting a wind turbine directly to a standard inverter will damage the equipment or cause the system to fail.
The Correct Order:
- 1. Wind Turbine — generates wild, fluctuating 3-phase AC as the wind changes.
- 2. Hybrid or Wind Charge Controller — converts it to steady DC, and protects the turbine from over-speeding with an electronic brake.
- 3. Battery Bank (12 V, 24 V or 48 V) — absorbs the gusts and provides a steady source of energy.
- 4. Off-Grid Inverter — connects to the battery, converting stored DC into AC for your appliances.
Why you Cannot Skip the Battery:
1. Unstable Voltage: wind changes second by second. Without a battery to smooth it out, a direct-connected inverter would constantly cut out.
2. Turbine Damage: when a battery is full or disconnected, the turbine loses its load. Without that resistance the blades can spin out of control in high wind and destroy the unit. The controller uses the battery connection to dump excess power and slow it down.
1. This turbine generates 3-phase AC power and cannot be connected directly to a battery, a solar controller or a home inverter.
- It must run through a dedicated wind charge controller (pure-wind or wind-solar hybrid) with a dump-load resistor. The dump load stops the turbine over-speeding and destroying itself in high winds once your batteries are full.
- Installation and commissioning must be carried out by a suitably qualified and licensed electrician.
- Cable, breakers, isolators and all protective devices are selected to suit your site and are the electrician's call, not ours.
It is almost always one of three installation issues. Check them in order.
Quick Checks — Tick as You Go
- Is the Meter Set to AC Volts (V~)?
- Does it Spin Freely Once Disconnected from the Controller?
- Is the Cable from the Mast Heavy Enough for the Run?
1. The Multimeter is Set to DC — The Most Common Mistake.
1. Measuring the three turbine wires with the meter set to DC volts gives a false reading near zero.
- Wind turbines generate 3-phase AC directly from the stator. Switch the meter to AC volts (V~).
2. The Turbine is Stalling Because of a Short.
1. The blades turn heavily and slowly, or lock up: if any of the three AC output wires touch each other, or the controller's braking diodes have short-circuited, it acts as a magnetic brake — the turbine can never spin fast enough to build voltage.
- Disconnect the turbine from the controller. If it frees up and spins much faster, the problem is a short in the wiring or a faulty controller.
3. Voltage Drop from Thin Cable.
1. Thin solar or automotive cable over 20 metres or more loses the power as heat before it reaches the controller.
- Use heavy cable between the mast and the controller on long runs — minimum 8 AWG, ideally 6 AWG. Final sizing is your electrician's call.
- The number in the name is a peak rating, not a promise.
- A turbine's rated output is measured at a specific wind speed — 10 to 14 m/s depending on the model, which is about 36 to 50 km/h — and most sites see far less than that 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 as the wind changes. That is physics, not a fault.
- As an example, the L2-2500 is rated 2,500 W at 11 m/s. On a decent steady coastal breeze of 7 m/s the manufacturer's own curve gives about 813 W. That is why we publish the full power curve on every horizontal turbine's product page.
- Where these machines earn their keep is time: they keep charging through the night and through the weather that shuts solar down.
1. If the display shows 0 W while the blades are spinning, that is a different problem — see the 0 W question.
- Not necessarily — this is one of the most common questions we get, and it is rarely a faulty unit.
- It is 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 Guide for the complete walkthrough, or the Set-Up Guide — or contact us and we will help you sort it out.
- Wire your bus bar and breakers before and after the controller, then power up in the right order. Getting the sequence right prevents almost all wiring issues, including the common "spinning but 0 W" problem.
- 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.

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 how much rain actually landed on the tank catchment last week. Wind and rain are the two things on a property that change hour to hour, and they are the two things almost nobody actually logs.

This is a two-piece Wi-Fi weather station. One sensor array bolts to a pole outside: three cups for wind speed, a vane for direction, a rain funnel, a louvred shield holding the temperature and humidity sensor out of direct sun, and a light and UV sensor. A small solar panel on top is its main power, with two AA batteries as backup. Every 16 seconds it radios its readings to a backlit console you keep inside. Plug the console into its 5 V adapter, join it to your 2.4 GHz Wi-Fi with the maker’s phone app, and it can also send the readings to an online weather service such as Ecowitt or Weather Underground.

And the part a turbine buyer needs said plainly: this time the maker does print a wind range and an accuracy figure. The manual gives 0 to 50 m/s, accurate to ±1 m/s below 5 m/s and ±10 % above that. That is a weather-station figure, not a calibrated reference anemometer. It is good enough to show whether your site has wind worth chasing. It is not good enough to promise yourself a number of watts.

Some things the supplier does not say, and we are not going to fill the gaps for them. The seller has told us the sensor talks to the console on 433 MHz, but we still don’t know the water rating or the adapter’s plug type. The mounting pole is not in the box either. Every one of those is in the Limits tab and marked “Not Specified by Supplier” in Specs.

What it Does

Wind Speed & Gust: wind speed and gusts from the three-cup anemometer, shown in km/h, m/s, knots or Beaufort (imperial too, if you want it).
Wind Direction: the vane reads through 360 degrees, shown on a compass display with the eight main points marked.
Rainfall: the funnel feeds a rain gauge in the sensor body; the console shows rain rate plus totals for the event, day, week, month, year and all time, in millimetres.
Outdoor Temperature & Humidity: read inside the louvred shield under the rain funnel, in °C and %.
Indoor Temperature & Humidity: the console reads the room it sits in, so inside and outside are on the screen together.
Air Pressure: a barometer in the console, in hPa, with a 24-hour bar graph and a weather-forecast icon.
UV & Light: a UV index and a light level in lux, both from the sensor array.
Time, Date & Moon Phase: the clock sets itself from internet time once the console is on Wi-Fi.
Stored Readings: highs and lows with time stamps, plus a history log the manual puts at 3,552 records. You set the recording interval on the console.

Key Features

Seven Readings Off One Pole: wind speed, wind direction, rain, temperature, humidity, UV and light all come from one sensor array, so there’s one thing to mount and one thing to level.
Solar Powered Sensor: the manual says the solar panel is the sensor’s main power. The two AA batteries only carry it when there isn’t enough sun.
Uploads Over Wi-Fi: the manual lists Ecowitt.net, Weather Underground, Weathercloud and the UK Met Office’s WOW. It can also send to your own site if that site uses the Weather Underground or Ecowitt format. You register with the service to get a station ID and password.
Set Up from your Phone: Wi-Fi setup uses the maker’s “WS View” app for iOS or Android.
PC Software: the manual points to “WeatherSmartIP” from Ecowitt’s download site, connected over the same Wi-Fi network. Its screenshots are from Windows.
High & Low Alarms: you can set alarms for indoor and outdoor temperature and humidity, pressure, wind, gust, rain rate, daily rain, dew point, heat index and wind chill, plus a time alarm.
Wind Chill, Dew Point & Heat Index: worked out by the console and shown with the live readings.
Bubble Level & U-Bolt Mount: two U-bolts and clamps hold the array on a pole, and a bubble level beside the rain funnel shows when it sits level.
Backlit Screen: Off, Low or High. The backlight only works with the adapter plugged in.
Readings Kept Through a Battery Change: the manual says the console keeps its data when you swap the batteries.

Free Standard Delivery. Allow 5 to 10 working days from the day you order. Allow 1–2 days for fulfilment. Regional and remote addresses can take longer.

Limits

This is the honest list. Some of it is what the supplier does not state, and on a wind instrument that matters more than usual.

Mounting Pole Not Included: the box has the U-bolts and clamps, not the pole. One page of the manual says a pole is included, but its own box list and the supplier’s photos say it isn’t, so plan on finding your own. The manual sizes the clamp for a pole about 25 to 50 mm across (our conversion of the manual’s imperial figure).
Batteries Not Included: the sensor takes 2 × AA as backup to its solar panel, and the console takes 3 × AA 1.5 V alkaline. The manual says never to use rechargeables, to use lithium in cold weather, and not to use alkaline below −20 °C.
Wi-Fi is 2.4 GHz Only: if your router runs 2.4 GHz and 5 GHz, the console has to join the 2.4 GHz network or setup fails.
Wi-Fi Needs the Adapter Plugged in: on batteries alone the console still shows the readings, but it won’t use Wi-Fi and the backlight won’t work. The supplier doesn’t state the adapter’s plug type.
Radio Frequency is the Seller’s Word: the seller has told us this station runs on 433 MHz. The manual also lists 868 and 915 MHz versions, and the console shows its frequency when it first powers up. We are not claiming it is approved for use in Australia or anywhere else.
Range Falls Away Through Walls & Steel: the manual gives up to 100 m in open air. Its own table also says metal blocks 90 to 100 % of the signal, so a steel shed or steel cladding between the pole and the console can cut the link.
Wind Accuracy is a Band, Not a Point: ±1 m/s below 5 m/s and ±10 % above, per the manual. No start-up wind speed is given and no calibration certificate comes with it. Treat it as a good indication, not a reference measurement.
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 IP Rating Printed: the sensor array is built to live outside, but the manual gives no IP rating or water resistance figure, for the sensor or the console. We are not going to call it weatherproof to a number nobody has stated.
No Approvals Listed: the manual names no RCM, CE or other approval mark.
No Model Number in the Manual: the supplier’s listing sells it as the A6-WS2320 and the console carries the “misol” logo, but the manual itself prints no model number.

Q & A

Will This Tell Me Whether my Block is Any Good for a Wind Turbine?

It gives you a running record of wind speed, gusts and direction where you mount it. That is the raw information you need, and most people never collect it. Upload it to a weather service and you get graphs as well, not just what you happened to see on the screen. What it will not do is tell you what a turbine will produce. That depends on the machine, the tower height, the terrain upwind and your battery setup. Wind at gutter height can also differ a lot from wind at the top of a tower, so mount the sensor as close to the turbine’s likely spot and height as you safely can.

Will it Work on a Property with No Internet?

Yes, for the screen. The sensor talks to the console by its own radio link, not by Wi-Fi, so the console shows the live readings and keeps its own highs, lows and history log with no internet at all. Wi-Fi is only needed to upload to a weather service and to set the clock from internet time.

Do I Need an App or an Account?

Only for the Wi-Fi side. Setup is done with the maker’s “WS View” app on iOS or Android, and to upload you register with the service you choose (Ecowitt, Weather Underground and so on) to get a station ID and password. The console works without any of that.

How Far can the Sensor Sit from the Console?

Up to 100 m in open air, per the manual. The same manual says to expect far less in a real installation where the signal passes through walls, and that metal blocks it almost entirely. Set it up with both parts close together first, as the manual says, then move the sensor out and check the signal holds before you bolt it up.

Which Radio Frequency does it Use?

433 MHz, according to the seller. The manual also lists 868 and 915 MHz versions (915 MHz for North America), and the console shows its frequency when it first powers up. We make no claim about its approval for use in Australia.

Can I Read Everything in Metric?

Yes. The console switches to °C, hPa, millimetres and km/h or m/s, and can also show knots or the Beaufort scale for wind. It can show imperial units too, but it doesn’t have to.

Can I Leave the Sensor Outside Permanently?

That is what it is built for: solar panel, rain funnel, louvred shield and a bubble level for mounting it upright on a pole. But no IP rating or water resistance figure is printed for it, so we cannot tell you how it copes with driving rain, dust or salt air. In cold country, use lithium batteries as the backup. The manual says alkaline should not be used below −20 °C.

Specs

Sourced from the maker’s manual and the supplier’s photos. The manual prints some conversions to imperial wrongly, so only its metric figures are used here. Anything the supplier does not state is marked as such rather than guessed. On a wind instrument, an invented figure is worse than a blank.

Wind Turbine FAQs

- Start with two questions: how much wind your site actually gets, and how much room you have.

- As an example, the L2-2500 is rated 2,500 W at 11 m/s. On a decent steady coastal breeze of 7 m/s the manufacturer's own curve gives about 813 W. That is why we publish the full power curve on every horizontal turbine's product page.
- Where these machines earn their keep is time: they keep charging through the night and through the weather that shuts solar down.
1. If the display shows 0 W while the blades are spinning, that is a different problem — see the 0 W question.
- Not necessarily — this is one of the most common questions we get, and it is rarely a faulty unit.
- It is 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 Guide for the complete walkthrough, or the Set-Up Guide — or contact us and we will help you sort it out.
- Wire your bus bar and breakers before and after the controller, then power up in the right order. Getting the sequence right prevents almost all wiring issues, including the common "spinning but 0 W" problem.
- 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.
