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

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

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 bought the 24 V turbine with the intent to integrate it with the existing solar system. The turbine does work and does produce electricity; under moderate winds that are not considered to be extreme in our area (<10 miles/hour), it produces ~20- 50 Wt of electricity, in agreement with the graph Pikasola has provided. This amount is small, but it is over 24 hours and a nice complimentary addition to the solar system, as when the wind blows, we do have a low solar power production in our area. The controller block is somewhat finicky as it is supposed to figure out itself if it needs to produce 12 or 24 Volts, depending on the turbine it is connected to. The first block we have gotten was locking into 12 Volts and we had to replace it with another block, that produced 24V. I have to acknowledge excellent customer support given to me in this process. I will continue experimenting with this turbine and will see if I can fully integrate it with my solar system. Again, the customer support is highly engaged, which really makes Pikasola to stand out among competition.

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!

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.
