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.

Cable is Where an Off-Grid Build Gets Hot.

A run that is one size too small does not fail loudly. It warms up. The terminations warm up with it, the voltage drop eats the charge your turbine worked for, and the controller never quite sees a full bank. Left long enough it ends at a discoloured lug behind a panel nobody has opened in months, and by then the damage is to the gear either side of it.

This is plain single core flexible wire — the stuff that connects a controller to a bus bar, a breaker to a battery, a switch panel to a load. Stranded pure copper in PVC, in eight sizes from 10 AWG down to 22 AWG, four colours, cut to 5, 10 or 20 metres.

The honest part, up front. The supplier publishes the nominal cross-section in mm², the strand count, the strand diameter and the overall diameter for every size — all of it is in the specification table below. It does not publish a current rating, and we are not going to invent one. Safe current depends on your run length, whether the cable is bundled or in conduit, the ambient temperature under an Australian roof, and the voltage drop you can live with. That is a number your install has, not a number a product page has.

What it Does
  • Controller to Bus Bar: the short runs between a hybrid controller, a breaker, a bus bar and the bank, where fine strands make a lug or a ferrule easy to land properly.
  • Van, Ute & Camper Builds: 12V and 24V accessory circuits behind panels, where solid core will not take the bend and work-hardens on corrugated road.
  • Earth & Bonding Runs: green with a yellow stripe is the earth colour, so the run reads correctly to whoever opens the enclosure after you.
  • Switch Panels & Enclosures: fine strands crimp cleanly into a bootlace ferrule instead of splaying out and half-clamping under a screw terminal.
  • Colour Coding a Whole System: black, red and blue in the same size, so polarity is obvious next time the panel is open instead of a guessing game with a multimeter.
Key Features
  • Pure Copper, Not CCA: the supplier states oxygen-free pure copper. Copper-clad aluminium looks identical at the end of a strip and carries far less current for the same size.
  • Fine Stranded Conductor: 28 to 84 strands depending on size, so it routes around a corner instead of fighting you.
  • Strand Count Published: the supplier gives the number of strands and the diameter of each one for every size, which is what lets you check the conductor yourself with a magnifier and a micrometer.
  • Nominal Size in mm²: 0.5 mm² up to 6 mm² across 20 AWG to 10 AWG — the figure an Australian or New Zealand sparky will actually ask you for.
  • Overall Diameter Stated: 2.25 mm to 5.5 mm, so you can work out gland size and conduit fill before the cable turns up.
  • Single Core PVC: one insulated conductor. No outer sheath over the top, no shield, no second core.
  • Four Colours: black, red, blue, and green with a yellow stripe.
  • Three Cut Lengths: 5, 10 or 20 metres, though not every length is offered in every size — the specification table sets out which.
Limits

Where this cable stops, plainly:

  • No Current Rating: the supplier does not state amps for any size, so neither do we. Size the run against your own current, run length, bundling and voltage drop, or hand the numbers to your electrician.
  • No Voltage or Temperature Rating we can Confirm: nothing legible in the supplier's photographs states either one. Both rows in the table read "Not specified by supplier" for that reason.
  • No Compliance Mark Sighted: no RCM mark and no AS/NZS 5000.1 marking is readable anywhere in the supplier's images, and no certificate was supplied. Fixed mains wiring in Australia and New Zealand is licensed work using cable that carries that mark — this is sold for low-voltage and DC work, not as a substitute for it.
  • The 22 AWG Size is Undocumented: the supplier's own size chart runs from 21 AWG to 10 AWG and does not include the 22 AWG option sold here, so its cross-section, strand count and diameter are all unstated.
  • Not for Burying or Open Weather: the supplier's artwork calls the PVC waterproof. There is no IP rating, no UV rating and no immersion figure behind that word, so we are not repeating it. Single insulated wire like this belongs in conduit, a loom or an enclosure.
  • Nominal is Not Measured: the mm² figure is the supplier's nominal size, the one printed on the sheath. We have not put a sample under a micrometer, and the strand figures are published here so you can check it yourself.
What Else you'll Need

Cable is one part of the run between a turbine and a battery bank. The rest of it:

  • Breakers, Isolators, Bus Bars & Lugs: the electrical supplies range covers the hardware at both ends of a run. Every input and output wants a breaker or isolator on it so you can shut down and isolate before you touch anything.
  • Shielded Signal Cable: sensors, displays and comms runs need a shield, not a bigger conductor. That is the shielded 2 and 3 core cable, and it is not for carrying charging current.
  • Controllers: you cannot wire a turbine straight to a battery. A hybrid MPPT controller rectifies the output, manages the charge and brakes the turbine when the bank is full.
  • Turbines: the vertical axis turbine range, if you are building the system rather than repairing one.

Q & A

How Many Amps will it Carry?

Not specified by supplier, and we will not print a figure we cannot source. Someone sizing a breaker off an invented number is a fire, so the honest answer is the useful one: safe current depends on the cross-section, the run length, whether the cable is bundled or in conduit, the ambient temperature and how much voltage drop you can accept. The table below gives you the cross-section, the strand count and the strand diameter. Your sparky can do the rest with those.

Is it Real Copper, or Copper-Clad Aluminium?

The supplier states oxygen-free pure copper throughout, and repeats it across four separate panels in the product images. CCA is the usual substitution in this category and it carries a lot less for the same size, so it is worth checking on arrival — scrape a strand, and copper stays copper coloured all the way through while CCA shows silver underneath.

What is Each AWG Size in mm²?

The supplier pairs them like this: 10 AWG is 6 mm², 12 AWG is 4 mm², 14 AWG is 2.5 mm², 16 AWG is 1.5 mm², 18 AWG is 1 mm², 19 AWG is 0.75 mm² and 20 AWG is 0.5 mm². The 22 AWG option is not on the supplier's chart at all, so its cross-section is not specified. Those mm² figures are nominal sizes, not measured cross-sections.

Can I Use it for 240V Mains Wiring in the House or Shed?

No voltage rating is confirmed and no compliance mark is readable on it, so treat it as unsuitable for fixed mains work. In Australia and New Zealand that wiring is a licensed electrician's job using marked cable, and this is sold for low-voltage and DC work — off-grid, vehicle, van and panel wiring.

Which Colours Come in Which Sizes?

Black and red are offered in all eight sizes, 10 AWG through to 22 AWG. Blue and green-with-yellow start at 16 AWG and run down to 22 AWG. The 5 metre length is offered on 16 AWG in every colour, and on 10, 12 and 14 AWG in black and red only — everything else comes as 10 or 20 metres.

Is it One Continuous Length?

Not specified by supplier. If a continuous run matters to your install, order the next size up in length so a join is not forced on you.

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.

    • 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.
