Enair 70 power curve

[John Szegda]

Hello Rob,

I installed a new Enair 70 Pro Turbine to replace a chinese 2kw. Do you have experience
tabulating a good power curve for this unit?

John Szegda

[Rob Beckers]

John, alas, that's one I've not heard of before. Could be the same as another one, the Chinese are really good at copying a design and selling it under another name...

In any event, with more info we may still be able to come up with a good power curve. Is this originally a grid-tie or off-grid turbine? Depending on the answer I'll have some more questions. If you have a link to a spec sheet that would be good too.

Hi John, do you have any photos? Was your old one an Emorok?

Hello Rob

The Turbine is the revised version of the Windspot. Enair is the Company that produced
Windspot, now build and sold direct. I did manage to get power curve from Enair (see attachment). To me it looks like allot of points to fit in the Aurora table.

The other issue I have is with the Aurora Installer and Usb Drivers I've downloaded, do not work with Windows 8.

Hello Andy,

How are your projects going. The turbines are Exmork 2Kw. If your interested, you can have free, if you pay shipping.

Hi John,

that looks like a good starting point and you will be able to miss out a few of those points and still come up with a good 16 point table. Can't help with Windoze 8 I'm afraid, I'm still using 7, which works just fine.

Good luck, Paul

Hello Paul,

Today, when you buy computer your forced to except a new Windows program.

Thanks for your reply,

The MPPT table? Just want to make sure before I delete it, it looks like a decent table (and no, you don't need all those points, especially on the straight sections all you need is a point at the beginning and end).

Regarding AuroraInstaller and Windows: There may be newer versions of the Texas Instruments USB drivers around, but the version on the Aurora inverter CD is for 32-bit Windows. The last version that worked on is XP.

The quickest way around it is by getting a simple RS485 interface for your PC. I've been using this one (http://www.robotshop.com/ca/en/devantech-usb-rs-485-interface.html), but there are many others that would work equally well (unfortunately not all USB-to-RS485 converters work with the AuroraInstaller program, it depends on the chipset that's used, so look for one what is known to work).

Rob,
I'm sorry Rob. I checked the attachment on another computer and it shows the correct curve. When I open attachment on my computer, it went back to my documents folder.
Can you edit the power curve when you have time. I do not grasp (beginning and end)

John

[Paul Camilli]

Yes, as RoB says it depends on the chipset, I've come across this a lot with RS485 to USB converters, the cheap ones simply do not work. Or they work intermittently then fail, I believe an FTDI chip is what you need, dunno where you are John but I got mine off eBay from a guy in Romania. Stick with it cos these Aurora inverters are brilliant if you're grid feeding.

Good luck, Paul

I use the digitus after trying a lot of others
this one works like a charme

And for the enair turbine
the "hands" are changed and also the pitch controll is totaly revised
The hood can open now so you can reach the generator
the brushes can be reached on the outsite now
the generator is 5000 watts
the blades are on the setting made round so they are stronger as they where flat

the set is delivered with a brake switch
choose between 3 phase or single phase ginlong inverter

in this tread we have discussed allready

How are your projects going.

Solar Great!

Windmill bad!...........Power One inverter blew in January. Windmill broke in March. Couldn't get up there until June. Got windmill to a 1st class motor repair place. Problem was slip ring wire rubbed while turning and shorted out. Not a big deal. Since it was down I asked them to put new bearings in. They kept it 3 month. Got it back and it wouldn't turn on the slip ring axis. Now they have kept it 3 more months so I probably won't get it back up this winter. Very Angry! They're in control, not me.

Nice of you to ask anyway John, LOL!

[Rob Beckers]

John, not knowing anything about your turbine's characteristics all I can do is follow the MPPT table as listed in your attachment. I'm assuming the listed values are DC Voltages, if not you need to multiply them by about 1.35 to convert to DC. So you'd get:

1: Power= 0, Voltage = 210
2: P = 300, V = 230
3: P = 780, V = 240
4: P = 1500, V = 250
5: P = 2790, V = 260
6: P = 3600, V = 280
7: P = 4200, V = 320
8: P = 5010, V = 460

Vstart = 210
Tprot = 300
Pramp = 5000

Rob,

Thank you very much for your time calculating the numbers. I will let you know what happens tomorrow.

Hello Rob,

I finally got all the kinks out from the Enair 70 Pro installation and it is flying beautifully in today's high winds. The power curve you compiled is perfect. The Turbine is producing an average 4253 watts. As I mentioned in previous post I purchased a Ginlong Wind Inverter, but could not get more then 172 watts. There is no logic to To Ginlong power curve setting. Luckily I found and fixed the ground issue in the PVI6000, so it's working. Thanks again for the power curve.

Hello Cor,

The setup you have is exactly the same as mine. It is amazing the power these units produce.

in Januar we visit the factory
looking forward to it

Good to hear it's working John!

The Ginlong inverters use a table with fixed Voltage increments, and you have to set a power value for each of the points in this table. It works the same way as the ABB/Power-One Aurora inverters, but is much more of a hassle to set up. IMO a bad decision on their part to this route; that's typical of inverter (hardware) manufacturers, they are really good at designing the electronics, and really bad at designing a decent user interface. I've seen that over and over (my background is in user interface design for software, so I tend to notice).

Aye RoB,

the Aurora software takes some beating for ease of use. The SMA 'Windy Boy Set up Tool' is a nightmare by comparison and doesn't even work with some of their wind inverters!!!!! I've been using an SMA WB6000 for some years now and could never get the tool to work so I phoned them up. They said "take off the cover and check the chip to see what version it is" if it's V? or below it won't work with the WBST!!! but if you send us the inverter we can upgrade it for £78!!!! then of course there is the delivery of a 60kg inverter to consider!!! I just make alterations using 'Sunny Data Control' but of course you cannot actually see the curve.

Cheers, Paul

Hello John,
Is your turbine still working? I am considering the latest version of the Enair-now a E-5 from Ryse energy in UK I think. I have a Windspot 3.5 that is suffering some bearing issues. I am not sure it is repairable. Where did you get the Enair? I am up in Ontario near Trenton.
Thanks
Pete

[Cor van Houtum]

Hello Peter
this are skf bearings and it is possible to replace

kind regards
Cor

[Ralph Day]

Hey Peter
Have you ever figured out how much of your power comes from wind? With our Bergey XL 1kw turbine (Midnite solar Classic 250 and Midnite Clipper for control) our wind component is always between 20 and 25% or our renewable energy generated/used.

Do you think it's worthwhile gambling on another bigger turbine (with all the problems you've had so far) if it's contribution is not that great? Still thinking of grid connecting? Our Hydro one bills are generally $50 (summer) to $90 (winter with some heat pump running).

Ralph

[Peter Klaassen]

Hi Ralph,
You are probably right that the wind production is not a big part of the total power bill. If it was only about cost we would be on the grid still and maybe with electric cars in our future the grid is the way to go. I am still interested in wind power but maybe I will make it more of a hobby and work on repairs to our existing equipment. When we are on a fixed income this will be more important.

[Cor van Houtum]

the numbers of the bearings

[Cor van Houtum]

It is magnetic so you need to set it in a workbench
make a clamp to make sure the positioning stays the same without the bearing

i find out if we have foto's
