H12-2000 Vertical Wind Turbine — 2000 W at 12 m/s, 48 V

Two kilowatts that don't care which way the wind blows. On a working property the wind rarely arrives clean. Sheds, silos, tree lines and machinery all chop it into gusts that swing through every point of the compass — and a conventional turbine wastes half of that weather swinging around trying to face it. Meanwhile the battery bank behind the workshop keeps sagging, and the generator burns another jerry can. The H12-2000 is the bigger of our two H-type vertical axis wind turbines — five aluminium alloy blades standing upright around a central generator on a die-cast aluminium body, with a printed rotor size of 1.55 m / 2.4 m. Because the rotor is vertical it takes wind from any direction, with no yaw mechanism to swing or wear: 360° auto windward, in the manufacturer's words. It starts working at 2.5 m/s and is built for properties, farms and off-grid work sites. Unlike the smaller H12-1000, this model runs a 3-phase AC external-rotor generator — a different machine inside, not just a scaled-up one. Straight up about the numbers: the 2000 W rating is measured at 12 m/s — a 43 km/h wind, not a normal afternoon breeze. The manufacturer publishes no power curve for any of its vertical-axis machines, so we cannot show you an output table for this one. We could calculate one and present it as measured — plenty of sellers do exactly that — but we would rather tell you it is missing. What the maker does publish: 2000 W at 12 m/s, a maximum of 2,100 W, charging from 2.5 m/s. On a normal usable breeze expect a fraction of the rated figure, working around the clock. Treat it as a serious charging assist for a big battery bank, not a stand-alone power station. What It Solves The chopped-up farmyard wind: sheds and tree lines gust wind from every direction. A vertical rotor takes all of it without turning to face any of it. The bank that never quite recovers: a 48 V shed or homestead bank that solar alone can't hold up through winter gets fed day and night, in any weather with wind in it. The grey winter week: the fronts that flatten your solar for days are exactly the weather this machine works hardest in. The diesel bill: every hour of breeze is fuel you have not hauled to the block and a generator service you have not done. The site nobody visits: telecom and monitoring installations that need real charging capacity without anyone there to point, adjust or maintain a yaw system. Key Features Takes wind from any direction: 360° auto windward — no yaw mechanism to hunt in shifting gusts or wear out. Five-blade H-type rotor: aluminium alloy blades on a die-cast aluminium body, printed rotor size 1.55 m / 2.4 m. External-rotor generator: 3-phase AC external-rotor build with NdFeB magnets, IP54 protected — a different generator from the H12-1000's synchronous unit, as the maker specifies it. Starts at 2.5 m/s: the maker publishes a single combined start-up / cut-in figure of 2.5 m/s (9 km/h). Built to survive 45 m/s: that is 162 km/h. If your site regularly sees worse, this is the wrong machine for it and we would rather say so. Two layers of protection: electromagnetic brake for overspeed, controller over-current protection plus dump load for overload. 48 V system: made for a 48 V battery bank — the voltage most serious off-grid banks now run. Two controller choices: the HCM wind-solar hybrid (runs panels too) or the heavy-duty pure-wind WW20-48-48 MPPT with a real, published 42 A output rating — pick either as a kit, or take the turbine only. Kit, Or Turbine Only The hybrid kit pairs the turbine with the manufacturer's matched wind-solar hybrid controller, the LHCM2-1/48V. The hybrid part matters: wind charges through MPPT, and the same box takes a solar array on a PWM input — one controller runs both. One honest caveat: the manufacturer publishes only series-level figures for this controller, not model-level ones — which is why there is no LHCM spec table on this page. Never going to run solar? Pick With Pure-Wind Controller and the kit ships the manufacturer's heavy-duty pure-wind MPPT unit instead — the WW20-48-48, with a separate dump-load box. Wind only, no PV input at all — and it is the one controller in this range with a genuinely published current rating: 42 A maximum output. Full details in the Specs tab. Odd but true: the manufacturer prices the pure-wind unit above the hybrid for this model. That is their pricing, published as printed — not a mistake on our page. 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 controllers) 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 H12-2000 you receive is this five-blade design, at the sizes in the spec table. Q & A Will it really make 2000 watts? At 12 m/s — a 43 km/h wind — that is the manufacturer's rating, with a published maximum of 2,100 W. On a normal usable breeze you will see a fraction of that, working day and night. The manufacturer publishes no power curve for its vertical machines, so we will not print an output table we cannot source — size your expectations conservatively and treat the machine as an around-the-clock assist for a solar bank. Why a vertical axis turbine instead of a normal one? A horizontal turbine must face the wind, so on a turbulent site it spends its time swinging back and forth chasing gusts. An H-type vertical rotor takes wind from any direction without moving anything — no yaw mechanism, nothing to hunt, nothing to wear. In clean, steady, open-country wind a horizontal machine of the same rating is usually the better harvester; in the chopped-up wind around sheds, trees and buildings, the vertical layout earns its keep. If your site is open and laminar, look at our L-series horizontals instead — honestly. What charging current do the controllers handle? The pure-wind WW20-48-48 has a genuinely published figure: 42 A maximum output current, printed by the manufacturer for this exact model. The hybrid LHCM2-1/48V does not — no charging current is published anywhere for the HCM series, and we will not calculate one by dividing watts by volts. Either way, do not size cable or breakers from the wattage in any product title — that is your electrician's job, from the real figures. Why is the pure-wind controller dearer than the hybrid? We noticed it too — for this turbine the manufacturer prices the WW20-48-48 pure-wind unit above the LHCM2-1/48V hybrid, the reverse of the smaller H12-1000. The WW20 is a heavier-duty box from their 2–5 kW controller series with a published 42 A rating; the hybrid buys you the solar input. We publish their prices as printed and leave the choice with you. 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 built to take more than the nominal battery voltage on its input. Cable selection and protection are your electrician's job. Can I mount it on the roof? The maker rates it for 3 to 6 m above the roofline, or 6 to 10 m on a ground mast. Be aware this is a substantial machine — it ships at 170 kg gross, and the manufacturer has not published the bare net weight — so have your installer confirm the structure can carry it before committing to a rooftop mount. On a working property, a ground mast in clean air is usually the better installation anyway. 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 45 m/s (162 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.
