M-800W Horizontal Wind Turbine — 800W at 12 m/s, 24/48V

Wind pulls its weight when solar clocks off. Running a house or a working shed off-grid means the battery bank is the whole story. Solar fills it while the sun cooperates — then comes night, then comes winter, and then comes the fortnight of weather where the panels barely wake up and the generator becomes a lifestyle. The M5-800 is the practical starting point for putting real wind into a household bank: a 2 m three-blade rotor, 26 kg, rated 800 W. It starts turning at 2 m/s, charges from 3 m/s, and it earns its keep in exactly the conditions that beat solar — night, cloud, and the blowy systems that sit on a forecast for days. Straight up about the numbers: the 800 W rating is measured at 12 m/s — a 43 km/h wind. On a decent 7 m/s coastal breeze you will see about 300 W, running around the clock. That is the honest planning number, and 300 W all night is a serious deposit into any bank. What It Actually Makes Wind speed Feels like Output 4 m/s (14 km/h) Light breeze 45 W 5 m/s (18 km/h) Flags start to lift 110 W 6 m/s (22 km/h) Steady inland breeze 200 W 7 m/s (25 km/h) Decent coastal day 300 W 8 m/s (29 km/h) Good working breeze 420 W 9 m/s (32 km/h) Strong breeze 560 W 10 m/s (36 km/h) Windy 700 W 11 m/s (40 km/h) Very windy 795 W 12 m/s (43 km/h) Rated wind speed 800 W, peaking at 830 W That is the manufacturer's own measured curve. At a steady 7 m/s this turbine makes about 300 W — not 800 W — and we would rather you knew that before you bought it. What It Solves The winter energy deficit: when solar drops to a third of its summer take, a 24-hour source keeps the household bank out of the red. The remote homestead: four hours from town is a bad place for a flat bank. A second, independent source is resilience, not luxury. The farm's always-on loads: water pumps, electric fencing, cool room monitoring — steady draws that never sleep, matched to a source that never sleeps either. The telecom or monitoring site: base stations and island outposts are this machine's home turf — constant modest load, no grid, nobody on site. Cutting generator hours: every windy night is fuel not carted and engine hours not accrued. Key Features 800 W rated at 12 m/s, peaking at 830 W — with the full measured curve published above. 24V or 48V: 48V halves the current for the same power, so long cable runs from a back-paddock mast get cheaper. 2 m three-blade rotor: reinforced nylon-fibre blades, 950 mm each, on a die-cast aluminium body. Starts early: turning at 2 m/s, charging from 3 m/s (11 km/h). Built to survive 50 m/s: 180 km/h. If your site regularly sees worse, this is the wrong machine and we would rather say so. Permanent magnet generator: 3-phase AC synchronous, NdFeB magnets, IP54, auto yaw into the wind. Two layers of protection: electromagnetic brake for overspeed, controller over-current protection plus dump load for overload. Two controller choices: the HECR wind-solar hybrid (runs panels too) or the pure-wind WCMD MPPT — pick either as a kit, or take the turbine only. Kit, Or Turbine Only The kit pairs the turbine with the manufacturer's matched hybrid controller for your voltage — LHECR0824 on 24V, LHECR1248 on 48V — plus the dump-load resistor. The hybrid part matters: the same box takes a solar array on a PWM input (up to 1000 W of PV on the 24V unit, 1200 W on the 48V), so one controller runs the turbine and the panels together. One honesty note: the HECR series is rated to 800 W of wind and this turbine can peak at 830 W. The manufacturer pairs them regardless; we have queried the headroom and will publish the answer when we have it. Never going to run solar? Pick With Pure-Wind Controller for the manufacturer's pure-wind WCMD unit instead — LWCMD800W-24V on 24V, LWCMD800W-48V on 48V, no PV input at all. Already sorted for control? Pick Turbine only. What Else You'll Need A mast in clean air, cable sized for the run, breakers and an isolator, and a bank worth feeding. Cable sizing depends on run length, voltage and current — that is your electrician's call.

Representative photos: the manufacturer supplies one set of photographs per turbine family, not per model. The M5-800 you receive is this design, at the sizes in the spec table. Limits It is not 24/7 power. It makes power when the wind blows and none when it drops. Run it alongside solar and a properly sized bank; do not plan a household around the rated wattage. The rated figure needs a 43 km/h wind. Most sites, most of the time, will see a fraction of 800 W. The output table on this page is the honest planning number. The matched controller sits at the top of its rating. The HECR series is rated to 800 W of wind; this turbine peaks at 830 W. That pairing is the manufacturer's own recommendation, but we have asked them about the headroom and will publish their answer. No charging current in amps is published for the matched controllers, and we will not invent one by dividing watts by volts. Do not size cable or breakers from the wattage in any product title. No certification claim. We have sighted no certificate that names this model, so we make no CE or RCM claim for it. It is not plug-and-play. Professional installation by a licensed electrician is a warranty condition — keep the invoice. 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. Q & A Will it really make 800 watts? In a 43 km/h wind, yes — and it peaks at 830 W. On a typical usable breeze of 5 to 8 m/s you will see roughly 110 to 420 W, day and night. Plan off the table above, not the title. Does the kit controller take solar panels? Yes. The HECR series is a wind-solar hybrid: wind charges through MPPT and a solar array connects to the same unit on PWM — up to 1000 W of PV on the 24V model, 1200 W on the 48V. Never running panels? Pick With Pure-Wind Controller — the WCMD unit has no PV input at all. Is the cable from the turbine AC or DC? AC. The turbine generates 3-phase AC; the rectifier inside the controller converts it to DC, and the DC charges the battery. The voltage on the tower cable rises with rotor speed — which is why the controller is built to take far more than the nominal battery voltage on its input. Cable selection and protection are your electrician's job. Is 800 W enough to run a house? Not on its own, and we will not pretend otherwise. It is a strong second source: several kilowatt hours on a windy day, delivered mostly at night and in weather when your solar is doing nothing. The right way to use it is wind plus solar into one bank sized for your loads. 24V or 48V — which should I run? Match your existing bank. Starting fresh, 48V moves the same power at half the current, so the long run from a mast costs less in copper and losses. There is no 12V version of this turbine. 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 50 m/s (180 km/h). If your site regularly sees more than that, this is the wrong machine for it. How long until it arrives? Built to order and sea-freighted — allow 6 to 8 weeks. Delivery is free to Australia and New Zealand. The kit arrives as separate boxes: the turbine, and the controller with its dump load.
