PikasolaWind Turbine Generator 400W 24V - 3 Blade 2.5m/s Low Speed Starting With Charge Controller, Windmill for Home

This is wind turbine number 3. We’ve had 2 Air X turbines fail in our winds and the Air X was incredibly loud. We have steady winds to 30mph and rare gusts to 100mph. We have a 40amp break switch and a rope tied to the back so we can “lock” it out of the wind when it gets to strong. Very quiet turbine. Today is gusts to 50 and I don’t hear it in my house. I’m waiting to save to buy another turbine.Update: Dec 01 had a ice storm that caused ice to hit the spinning turbine. The blades are well built and took the impact resulting in a small chip in one of blades. I emailed pikasola and they immediately sent me a new turbine blade. Well built product that handles wind better than other turbines I have purchased. Have 2 and looking to get more.

Overall this wind gen is pretty good for the price. It should really be advertised as 100 watts, since it takes over 30 knot winds to achieve anything close to 200 watts and storm force winds to exceed that. I live in a very windy area so it consistently produces decent output. I’m running 1 kw of solar as well so the wind gen pulls to help charge the batteries when it’s cloudy a few days in a row. This was the second one I’ve purchased. I ran the last one hard for three years and the output was really dropping. I replaced it with the same one so I’d have spare parts onhand.One small complaint was the sticker placed on the leeward side of the blade. It’s the annoying paper sticker that is impossible to remove and junks up the look of the product. It leaves sticker scar and does affect airflow over the blade. I hope the company ready this and stops putting stickers on the blades.

I like the design of the turbine aesthetically. However I do not enjoy that the spec. Sheet given with the turbine as well as the sticker on the housing is listed as a 12/24v product but the turbine itself only produces 12v. Its possibly still useful to me but not for the purpose that I bought it. But if you need a 12v turbine this will do the work if its windy around where you install it.

The media could not be loaded. Does it work as specified in Wyoming, "the windiest place on earth"?? In a word, NO. The maximum output power is less than HALF quoted at all wind speeds. Even at 45mph, the highest power output is only 180 watts. The fan can run all day and night at 10 to 15 mph and never generate any charge, because the output voltage never gets higher than the 24-25 volts of the battery. Also, there is also NO way to slow the fan down to keep it from blowing up in high winds. I installed an expensive dump load resistor and controller $$: no effect. I also shorted the fan output as specified- no effect when winds are over 15 mph. It will run until it blows apart- no way to control the speed.The noise from the bearings is deafening-- hearing protection inside is MANDATORY! Also, noise to the neighbors 1/4 mile away is very concerning.TIP; you MUST balance the blades by ensuring the tip-to-tip is exactly equal distance or the vibration is severe. Good idea is to weigh the blades before installation.Customer service was good but they cannot fix a really poor design, and Amazon refused a refund.Bottom line: I spent a LOT of money for nothing, but frustration. Don't waste your time or $$$ on these chinese alternators.UPDATE: After weeks of research, I found a partial fix... The original bearing (dual bearing) was so bad grinding and noisy. I was able to rebuild the turbine with new american made bearings via amazon, and a custom spacer. This reduced the grinding noise 99%. As there is no way to slow the turbine down in high winds, I have to run a line to the tail and rotate the turbine 90% to the wind, tie it down, and short out the AC input. This technique will stop the turbine from blowing itself apart in high winds. It feels like these turbines are designed for 12v systems, even tho they are marked as 24V. They don't generate any charge power until over 14 mph, usually only 0.1 watts. A 35 mph wind gives only about 140 watts. The maximum power I've measured is only 200 watts. Be sure the blade tip-to-tip distance is EXACTLY equal.UPDATE 4-6-24 Less than one year, the turbine BLEW UP today, sending blades and shrapnel all over the area and into the house. Wind was 55 mph at the time. The tail lanyard came loose in the wind so the turbine turned into the wind and was running at a terrible speed, even tho the controller and switch were shorted OFF. No way to shut it down. It sure didn't survive the 89mph specification. One partial blade was buried into the ground and might have been lethal if I had been under the turbine. The unit is destroyed- but at least I have a spare set of bearings!

Buying Chinese is usually like a bad box of chocolates. You never know what you're going to get but don't expect much. This time I was pleasantly surprised.Well-packaged double corrugated cardboard. Rigid molded Styrofoam. Assembly tools included. Directions in chinglish of course but easy to follow none the less. Quality materials.Performed about as I expected. This is where most of the reviews on this and similar products go astray. Don't expect 400W from 15 mph winds--or even 30mph. The performance chart is based on "ideal" conditions. Back down your expectations by 50% and you'll be pleased.Customer service by email is great. Response within 24 hours even though there's a significant time difference.One concern though. This is probably a knock off. In fact all the Chinese made mills look identical to other far more expensive products. Longevity? Performance? Infringement? Who knows?Updated April 7 2022Pikasola gave me a full refund 2 - 3 months ago (bad bearing)Performance: about 100w at 30mph

We mounted it late December however we’re in the slow process of building a new controller. Never got it hooked up. We did the recommended short circuit to put a brake on the blades. Mounted it At recommended height. In retrospect I would mount it much lower to allow some wind breaks. We’ve had some gale force winds and the nose cone flew off yesterday. Sounded like the bearings were out but too high and windy to do anything about it. On the ground when we got home this afternoon. Not for high wind areas.

The media could not be loaded. Works great and customer service is very helpful if something breaks or goes wrong. I live off grid and this helps keep the power on at night when the wind kicks up but my solar power is no good. I recommend pairing these with deep cycle batteries for consistent power that won't need much attending to once its up and secure.
