G-3000 Horizontal Wind Turbine — 3000 W at 10 m/s, 240 V

Property-scale power that doesn't clock off at sunset. A cabin gets by on a few hundred watts. A working property does not. Pumps, a cool room, workshop tools, the house itself — the loads run day and night, and every grey week the generator becomes a daily fixture and the diesel run into town becomes routine. Panels alone can't carry a site like that through winter. The G-3000 is the smaller of our two G Type heavy-duty machines — 215 kg of die-cast aluminium and steel swinging a 4.8 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 3000 W rating is measured at 10 m/s — a 36 km/h wind, not a normal afternoon. On the manufacturer's own curve it makes about 2,880 W at that rated speed and peaks at 3,120 W at 11 m/s. At a good steady coastal breeze of 7 m/s you will see about 1,180 W — working around the clock. This is a big machine and it wants a genuinely open, genuinely windy site to earn its money. What It Actually Makes Wind speed Feels like Output 3 m/s (10.8 km/h) Cut-in — just starting to turn 0 W 4 m/s (14 km/h) Light breeze 210 W 5 m/s (18 km/h) Flags start to lift 450 W 6 m/s (22 km/h) Steady inland breeze 780 W 7 m/s (25 km/h) Decent coastal day 1,180 W 8 m/s (29 km/h) Good working breeze 1,720 W 9 m/s (32 km/h) Strong breeze 2,350 W 10 m/s (36 km/h) Rated wind speed 2,880 W 11 m/s (40 km/h) Peak output 3,120 W 12 m/s (43 km/h) Very windy 3,070 W 14 m/s (50 km/h) Near gale — output falls away 2,350 W 16 m/s (58 km/h) Gale 1,200 W That is the manufacturer's own measured curve, and we would rather you saw it before you bought. What the 3,000 W in the name means: that is the most this turbine makes, and only in a 36 km/h wind. On a normal breezy day — 7 m/s, about 25 km/h — it makes about 1,180 W. Work out your battery bank and cable from the table above, not from the number in the name. What It Solves The diesel habit: a property generator that runs every day is fuel hauled, services logged and hours you never get back. Every windy hour is load the genset doesn't carry. The grey winter week: the fronts that flatten solar for days at a stretch are exactly the weather a 4.8 m rotor works hardest in. The night shift: cool rooms, pumps and house loads pull all night while panels do nothing. Wind charges the bank around the clock. The remote site: telecom bases, island installations and out-stations where a service call is an expedition — which is precisely why the manufacturer fits the serviceable mechanical brake. The undersized system: if a small turbine and a few panels never quite carry your site, this is the scale where wind starts doing real work — kilowatts in a working breeze, not watts. Key Features Heavy-duty build: 215 kg net, die-cast aluminium and steel body, reinforced FRP blades on a 4.8 m three-blade rotor. 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 — 63 A. Kit, Or Turbine Only The kit pairs the turbine with the manufacturer's matched controller: the WW30-48-240, 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 3 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-3000 you receive is this design, at the sizes in the spec table. Q & A Will it really make 3000 watts? At its rated 10 m/s — a 36 km/h wind — the manufacturer's curve shows about 2,880 W, peaking at 3,120 W at 11 m/s. On a typical usable breeze of 5 to 8 m/s you will see roughly 450 to 1,720 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 WW30-48-240 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 63 A into the 48 V bank, printed by the manufacturer for this exact model. Be careful with the other number on its sheet — the 13 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 is still 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 215 kg machine with a 4.8 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 2.6 m blade-and-mast crate, 250 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 (38.6 kg) with the dump-load box inside.
