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 4 to 6 weeks (up to 7 for WA and regional addresses).

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.
