  • Windmax HY-2000 2kW Wind Turbine

    I've had a HY-2000 2kW wind turbine up for about 1 month now, and I am happy with it so far. The power output has been better than expected and better than the charts posted by the company. The quality seems very good. Time will tell how it holds up. I read about others with Windmax wind turbines that were happy, so I decided to give it a try. So far I am happy with it.

    I was embarrassed to share pictures of my system and setup, because I'm a bit of a "redneck" and my system is not professional by far. If I have trouble with the HY-2000 wind turbine then I'll plan to let you know. I know that much of the stuff coming out of China is junk. I've been burned by that fact more than once. However, I will honestly say that this seems to be well made. I've got a mechanical engineering background and so I can usually get an impression of overall build quality. Of course, time will tell how it holds up.

    So far, so good.

    PS. I will say this... in my opinion, it's probably best for most do-it-yourselfers to stick with the HY-1000 1kW or smaller turbines. I like the larger HY-2000 and HY-3000 units, but they are bigger, heavier and harder to set up.

    Re: Windmax HY-2000 2kW Wind Turbine

    So far, I'm happy with my 500 watt Windmax H5. The deciding factor when I bought it was the CE approval--wind is big in Europe right now and European code is stricter in some aspects than US code. They seem to be solid well designed units. A simple basic wind turbine with no electronics in the turbine itself, just a 3 phase alternernator and all control electronics on the ground in a seperate box. My Windmax turbine replaced one of Southwest Windpowers earliest products, a Windseeker 250 which was certainly well built and produced power for around 20 years and could easily be rebuilt even after 20 years of constant use but the built in controller in the turbine never worked and I had to buy another controller for it and install it on my power panel and Southwest Windpower continues with this design folly to this day. Nothing like putting the most delicate and fragil part of the system where it will be subject to weather, constant vibration, mechanical stress and lightning. And when the controller fails, you are forced to lower the tower and remove the turbine to service it.

    The Windmax turbines have a much simpler and better design.

    The one thing I don't like about the Windmax is the quality of the electrical connecters on the controller box which aren't designed for the types of cable available in the US and they will never get UL approval until they put better quality connectors on the controller box with strain reliefs positioned properly for them.

      Re: Windmax HY-2000 2kW Wind Turbine

      After a couple weeks of generally calm winds, we had some windy weather today. Wind was blowing around 20-30mph for a while. I was seeing peaks of 3000 watts at different times. Quite a few times it was cranking out 2500 watts. And now the winds are averaging in the teens and I'm seeing 500-1000w.

      The interesting thing is that the HY-2000 wind turbine is rated at 2000 watts at 26mph. Peak output on the HY-2000 power output chart shows around 2400-2500 watts. It is a case where the HY-2000 actually puts out what they rate it for (and more). Almost surprising to me that a Chinese company is probably more honest than many American companies in the rating of their wind turbine output.

        Re: Windmax HY-2000 2kW Wind Turbine

        I have a 400 watt WindMax which I bought solely to augment our system. We have 2kw in solar panels running through a pair of Xantrex MPPT controllers charging our 1200 amp hour battery bank at 24 volts. The solar panels work great down here in our part of Baja, Mexico but I wanted to try the wind turbine to see how well it could provide additional charging at night. Our part of the peninsula is very windy facing the Pacific ocean and we have been very happy with the performance so far. In fact we have purchased another turbine and will be installing it in the next couple of weeks.

        One suggestion - Throw out the stock controller and buy a good rectifier and diversion controller from Coleman Air to operate your WindMax...

          Re: Windmax HY-2000 2kW Wind Turbine

          I agree the controllers are often not the greatest on Chinese wind turbines. The controller on my HY-2000 is not bad. My biggest complaint would be that it came with a 62AMP fuse on the DC output circuit going to the battery bank. This does not have enough of a safety buffer to accomodate power surges. I was seeing 60AMPS at times yesterday during strong gusts! That's way too close for comfort with a 62A fuse. The last thing you want to have is the fuse burn out and inadvertently disconnect the wind turbine from the battery bank in high wind gusts!

          I bypassed the 62A fuse assembly because there was no larger amp rated fuse in that size available. I just used a more appropriately sized circuit breaker.

          I do have a Coleman air diversion controller that diverts power to an auxillary hot water heater in my home. If the hot water heater thermostat shuts off, then the HY-2000 controller dump loads the 3 phase AC turbine output directly to a set of heating coils that heats air.

            You might want to look at picking up a good rectifier and just buy another diversion controller for your application. I bought this one from ColemanAir and it seems to work great - the specs should fit your turbine based on what you described:

              Re: Windmax HY-2000 2kW Wind Turbine

              BajaGringo, That would be another viable option. I actually prefer the the HY-2000 controller because it is programmed with safety features that I would not get with a separate rectifier and generic diversion/dump controller. The HY-2000 controller is programmed to automatically apply electromagnetic braking when turbine RPM exceeds certain limits. This continual monitoring of turbine speed is important to me. Sure, I could manually shut down the wind turbine during a really bad windstorm, but I would not be able to react fast enough under all conditions around here. We get some powerful wind storms around here that some times come up very quickly. One year, we had a nasty wind storm that snapped off around 100 big utility poles like they were flimsy toothpicks.

              I've also inspected the controller and the rectifier assembly is mounted to a nice, big aluminum heat sink. The dump load from the HY-2000 controller is a separate unit that can be mounted away from the main control unit to prevent heat from the dumpload affecting the rectifier and other circuitry. Looks to be a decent design. I can't comment on the controllers from smaller Windmax wind turbines, and they might not be as good a design.

                  Re: Windmax HY-2000 2kW Wind Turbine

                  This thread has been inactive for a few weeks, so Iíll revive it with some info from another Windmax Turbine user here --- an HY-1000 1KW unit.

                  Itís an off grid --- pheasant and deer hunting camp site, I have here in central South Dakota feeding an RV (5th wheel trailer).

                  Last month it made it through a pretty severe stress test. We had a major high wind system go thru this area with continuous 45 to 55 mph winds and gusts to over 60 mph --- lasted over 3 days.

                  I have it set up as a 24 volt system and had steady output readings on the TriMetric TM-2020 in the 50 to 55 amps and at times over 60 amps at 29 volts --- that is about 1.8 KW --- almost double the rated spec. When the output gets into the over 50 amp range you can hear the blades flutter and moan as the tips bend to flex / feather and control the over speed. Normally, it is an amazingly quiet unit.

                  This unit has 5 blades and is rated at 1Kw at about 825 rpm with about a 28 mph wind driving it. Interpolating from their output charts --- it looks like a 1.8 Kw output from a 50 to 55 mph wind is turning the blades at over 1400 rpm, no wonder they were fluttering and moaning.

                  I also did not use the controller that came with this unit, but went with a Xantrex C60 set up as a diversion controller and built my own load dump unit.
                  The load dump unit is made up of 12 -- ten ohm -- 100 watt resistors in parallel and also a couple of 24 volt box fans controlled by a 120 F thermal switch --- works well.

                  This site in Central South Dakota has 15 to 20 mph winds about 3 or 4 days out of each week and works well on a 24 volt system. In a relatively lower wind speed area --- it may be better to set it up as a 12 volt system though. A 10 to 12 mph wind will turn at what looks like pretty good rpmís but not high enough to get the voltage up to the 27 volts or so to charge a 24 volt system.

                  Itís all a trade off though and there would be pros and cons --- and in the real world, there is very little energy available in a 10 mph wind until you get into really long blades.

                    Re: Windmax HY-2000 2kW Wind Turbine

                    Interesting. It looks like the owners of the 5 blade Windmax turbines are getting much better performance than with the 3 blade models. I haven't gotten nearly the performance of some of the 5 blade HY-400s I've seen on Youtube. So far my 3 blade HY5 hasn't put out anything like it's rated wattage at higher wind speeds but it's low speed performance has been totally up to spec. I was getting about a 8-10 amp average with peaks at around 16-17amps the other night when we had some winds but nothing in the 20 plus amp range. This indicates I might have some voltage drop in the wiring but I haven't found anything significant so far. One thing I've noticed is that the turbine will shift back and forth a few degrees at higher wind speeds which immediately drops the current a few amps. I didn't have this problem with my old turbine. It might mean the tail should be a bit bigger and longer. My site is not perfect and I am likely to get turbulence from one direction but this seems to be happening in winds coming from all directions. In any case, until I put up some sort of anemometer, I won't have any real data on wattage vs wind speed.

                    The controller works very well. At the amperages I'm getting, it is not stressed at all and I have been doing temperature readings when the turbine is really cranking and the rectifier heat sink is only a couple of degrees above ambient temperature and when the controller is dumping, the dump load is, at most, around 10 degrees above ambient temperature. The one thing I don't like is that it just starts dumping when the voltage reaches 14.1 volts and stops when it drops below this point. It would be better to have 2 adjustable trip points that would hold the contoller in dump mode until the battery voltage dropped to a settable low voltage. What happens when the batteries are charged is that the controller will dump for a few seconds and then the battery voltage will drop below 14.1v and it will charge again for a few seconds until the battery voltage reaches 14.1v and then the cycle will repeat. I have 2 solar arrays on 2 separete controllers that I have to integrate with the wind controller and this one doesn't give me much flexibility.

                    @Wally. You live in one of the better wind energy areas of the US. If you check out a wind energy map of the North America, anywhere in the great plains is good with some places really good. I live on a desert mesa in Northern New Mexico where wind energy is a good supplement to solar but you could never live on wind alone. I'm at around 7000' altitude with the Rocky Mountians to the east and some smaller mountains west of me. Once you get east of the Rockies, wind energy potential goes up dramatically.

                      Re: Windmax HY-2000 2kW Wind Turbine

                      Wally,

                      That is some serious power out of that HY-1000! I've also seen 3.5kW surges out of my HY-2000. The HY Energy factory rates these wind turbines conservatively.

                      You are braver than I am... with those kind of high winds, I probably would have tried to shut down during a lull in the wind gusts. If the power output gets too high (too many amps), then the stator winding could burn out. I don't know how much factor of safety they design into these HY wind turbines. This time of year, with the colder temperatures, then turbine might be able to cool sufficiently during sustained high power output. At some point though, there will be too many amps flowing through the windings in the stator and it will get too hot and melt down (short out). Then you have a ruined turbine and a runaway turbine that is free to spin out of control with no electrical load to try to slow it. It could then throw a blade. Perhaps the blade deformation and stalling will not allow it to get that high in power output to melt down the stator. Not knowing the limits is what would make me nervous.

                      My perspecitve is based on having a different brand 2kW wind turbine that had the stator burn out and run out of control for about 1 hour. Talk about LOUD. Sounded like a helicopter was landing on my house. Thank God that it didn't throw a blade. Almost. There was cracking around the attaching holes on one of the fiberglass blades. That bad experience is permanently etched in my mind!

                      I'm now in the process of trying to figure out how to limit power output (RPM) on my wind turbine for long term safety and reliability. In my case, 2.8kW equates to around 650 RPM. That's about where I'd like to limit it.

The guy I talked to was just rude!

                        All I really need is a big rubber bushing that is used on the tail. I'm about to put this thing on a 38ft tower but need to replace the rubber bushing. I can't believe there are "no parts" available.

                          RZ, Based on what you wrote, it sounds like you've got a 1kW V10 or 2kW V20 wind turbine with tail furling.

                          I had the same type turbine as the V20, but I bought it somewhere else other than Windmax. In any case, it's the same turbine design.

                          The rubber bump stop for my tail also disintegrated, so I cut a piece of rubber out of a small scrap radial car tire I had laying around here. I used this as my new bump stop. I'll attach a picture here.

                          Unfortunately, the whole turbine failed a short time later (stator burned out). You will find that it is almost impossible to get parts or help after the sale. Even if you could get another rubber bump stop, it would fail in a short time anyway because of the inferior materials that they use.

                            It looks like the HY turbines are generally good and well made but due to this lack of support, I find it hard to recommend buying one from magnets4less. I'm a bit dispointed in the real world power output of my turbine which is turning out to be a 300 watt turbine with it's stock 3 blade rotor. In checking out the possibility of of an upgrade to a 5 blade rotor, there are none available from magnets4less but I found this company makes 5 and 7 blade upgrades with a hub adaptor specifially for Windmax turbines:

                            http://cgi.ebay.com/7-Wind-Turbine-G...item3f04f5dabb

                            http://cgi.ebay.com/Windmax-wind-tur...item3f04c81c4a

                            I just found these ebay listings but I knew about the raptor blades for the HY turbine from the Youtube video they put up about it and checked out the company website. I'm thinking about buying a 5 blade rotor from them but I'm not going to do it until I've seen how the turbine performs under really high wind conditions which hasn't happened so far this year. Last year at this time, there was was a winter storm that had such severe winds that after the storm cleared out, all the east-west roads were snow free because the wind had pushed the snow into huge banks on the side of the road while the north-south roads had around 8 inches of snow. This year, the weather has been unusually mild and the snowfall so far has been around 1/4".

                            I also looked at Missouri Wind and Solar's turbines and they are actually cheaper than the Windmax turbines and it looks like you have a lot better chance of getting replacement parts. If anyone has tried one of their turbines out and dealt with them, I would be interested in hearing about it.


                            @keyturbocars

                            I've been reading your posts with interest and have been thinking about ways to brake a 3 phase turbine in high wind conditions. Unfortunately, I haven't seen any winds so far that have given me a good high wind test and some serious motivation and my problems with my HY turbine are in the opposite extreme. My thoughts so far are that a progressively increasing load between the the 3 phase lines until the the rpm slows down enough to put a dead short between the lines would be one approach. There are all kinds of ways to do this. If you could get big enough variable resistor and gang 3 of them together and put them across the 3 phase lines, you would have tapered load that could be controlled manually. The only variable resistors that I've ever seen like that were WW2 era airplane controls and I don't think you could find anything like that on the market today. A power mosfet circuit might be a modern alternative. This is really a controller design idea. A quick and dirty trick would be to put a high current spdt switch between the controller and the dump load which could bypase the controller and force the DC output into the dump load and then put another dump load in parallel with another switch which in theory would progressively load the turbine output and slow it down in stages. If 2 stages weren't enough, another switched dump load could be added easily. High current DC switches and dump loads are easy to come by and not very expensive in comparison to even the most basic 3 phase high current equipment.

                              Mister B,

                              Those are good ideas about braking. I've got some similar ideas on ways to load down the turbine and then after the rotor has slowed down sufficiently, flip the 3 pole switch to short out the 3 phases. Right now, I have the old controller from my previous 2kW wind turbine hooked up to my HY-2000 turbine.

                              Even though that other turbine that failed was inferior in quality, oddly enough the controller appears to be a much better design. It's a MOSFET controller that uses PWM to dump the load. I can flip a switch on the controller to manually trigger the MOSFETs to dump the turbine output to a 4kW resistive load. Then, once the turbine slows down under the heavy load, I can short out the 3 phases. The other reason I like this MOSFET controller is because it was also programmed to pulse the 4kW load under higher wind speeds to try to keep rotor RPM under control. The circuit must have monitored the freqency of the incoming 3 phase AC and applied PWM dump at a set frequency that was to ensure safe turbine RPM. What I don't know for sure yet is if this controller's RPM limit will be too low for the HY-2000 turbine. In other words, it might try to reduce RPM too early and chop off the top end of the power curve prematurely. I'll have to wait and see what it does when we have some high winds again. We are in a seasonal lull of winds now.

                              I'm doing all this while I wait to see how the Midnite Classic/Clipper ends up working.
