2000 watt wind turbine grid tie inverter: still struggling

[@behappymike]

copied from the updated manual I've just got...
Set Menu: Choose the set menu icon on the main screen interface, click the confirm button to enter into the interface shown below. In this interface, the LCD backlight can be set to always on or auto turn off after 3 minutes no action.
The inverter also integrates with limit function, preventing excess power from going to the public grid. Select the limit mode, the inverter will work under limit mode. The inverter's output power will be determined by load power.
"Shortcut" option sets the input voltage point of the inverter disconnecting from the wind turbine. "Dumpload" option sets the dump load resistor shift-in input voltage point.
"Current curve adjust" option sets the P-V(power to voltage) curve of the inverter to fit the P-V curve of the wind turbine.
Actually not much use however based on the above you want the
"internal limiter" unchecked
"Shortcut" set to something like 100v as my head is saying you dont want it disconnecting until its a serious gust
"Dumpload" set to something like 90v as again my head is saying why would you want the dumpload kicking in before then?

[@stephenbuckley2186]

mine seems to have a timer once the shortcut has been activated and voltage drops to zero (when I short the turbine) maybe to let things cool a bit? I can hear it click and it all starts up again with no power to the dump load. The dump load also acts to reduce voltage so when the dumpload point is reached it will divert some power to it to keep the voltage below the shortcut setting so the settings need to be different, maybe 70 volt for dumpload and 85/90 for the shortcut when it disconnects the inverter from the mill and all power goes through the resistor. You can use a three phase switch to shut the turbine down then switch off the power to the inverter, switch it back on switch off the turbine shut down and it will all start up again, output from a turbine can increase really fast from a gust of wind and the inverter cant follow it fast enough so if the dumpload is set fairly low it has a longer time to adjust before it gets to the shortcut voltage and disconnects. It needs playing with.

I think this unit has a snag. I have the same and hoocked it up to the drillpress for a test and like youres it puts on voltage at the dump terminals same as shown in display from generator but when i connected the resistor voltage goes to zero. And heat element is cold. It only came on when I reaced the dump voltage limit. So it seems to work ok on mine.

[@stupidmonkeykev]

Have you played with the dumpload tickbox, voltage box. I wonder if "shortcut" is also brake? and that tickbox + voltage to play with?

[@ToysforWatts]

Yep I've tried both options in every combination, there was no change.

[@ismscsim]

When you opened the unit one of the 3 turbine inputs looped to the dump load directly....seems strange it does that?

[@dalerussell9075]

Have you tried feeding the turbine into a battery bank or capacitor bank just to smooth out the voltage.....I wonder wheather as well as your inverter stuggling with over voltage but also the mppt tracking might not be able to keep up with such a rapidly changing voltage and amperage.....cap bank might cure both issues....good work and good luck look forward to your next vid

[@raffaelesaccullo4212]

Hi, I would like to buy ina Istabreeze I 2000 to be connected directly to the inverter that you are testing and connect everything to the grid. Do you think this is feasible? Thanks for your attention.

[@randylenart9674]

Is there a setting for the input voltage mabe it needs raised says input voltage to hi

[@cadplast2480]

I have one of those gtil for my 1000w istabreeze, been working flawless for 2 years. I use the same resistor no problem. One must understand the settings in the menu. Use custom power curve and max out the last voltage-step

[@cadplast2480]

I can also confirm the resistor is way underpowered even for my smaller turbine, but i havent come to change it yet.

[@gerbenstok2428]

Can you send me an screenshot of your settings? bought last week one for my 1kw too. thx!

[@raffaelesaccullo4212]

Hello Cadplas24, I would like to buy ina Istabreeze I 2000 to be connected directly to the inverter that is testing Toys for watt and connect everything to the grid. Do you think this is feasible? Thanks for your attention.

[@liambyrne8248]

@@raffaelesaccullo4212 I also buy I2000 48v istabreeze and this inverter, I have yet to test it as I am waiting for the blades to arrive
I did test it with a power drill got 500watt but burnt out my drill in seconds:(
I would love to know what settings work best also before I do some damage ;(

[@pgfox2002]

Could you please post your settings for the power curve? Really appreciate this as would be a good starting point for many on here Maybe we can combine our knowledge on here to get the ideal settings for the istabreeze 1000, 1500 and 2000. I’ve found so far that using small settings at the low voltages has already helped. But struggling to get any good power from the unit. My max is around 700w briefly for the i2000

[@thebrokenpallet2557]

Send that unit back. Dont get the wind turbine version. Grab the other one. Continue to feed the power to your batteries and then run the inverter from the batteries.

[@paramax55]

Do like The Broken Pallet said... use the other version. Mine has been awesome for the money. But I like solar to produce power, charge controllers to charge, batteries to buffer, and inverters to invert. My setup is solar->charge controller->batteries->inverter->grid. Your charge controller(s) is/are working to charge the batteries... try hooking the inverter to the batteries and operate it that way.

[@stephenbuckley2186]

the resistor that came with mine is 10 ohms and istabreaze recomended 4 ohms for the i 2000 48 volt that I bought.

[@solarandwind9442]

hey deh am from the caribbean an i watch all your videos i see u have problems with your inverter working together with the wind turbinne i guess u can contact dave collier from 2019 he has that inverter working with his wind turbine an he knows how to set it up u can watch his videos as well

[@alessioat]

for a 2 kw turbine you need two grid inverters, since that type of grid inverter is 1.8kw of effective power. The dunpload power resistor must be replaced with a higher quality one

[@garys-half-baked-offgrid-dream]

Excuse my naivety but If this is grid tied I would of been thought the dump load only kicked in if the grid went down?
When I was shopping for mine there is an older version with no export limit function and a newer one with a export limit function.
Have you got a newer one with the limit function activated? Those setting screens look confusing as hell, I am not looking forward to this now.
Failing that, turn everything up to 11 and let her fly! 🤣

[@margusten1]

I have similar device in use only 1500w IstaBreeze 24V feeding it. Grid tie inverter factory settings, I believe , Shortcut and Dumpload not ticked 52V last setting 19A. 23V first setting 0A, I have. One day in high wind this resistor was glowing and inverter not producing electricity. I set brake to wind generator and it went normal soon. Then it started to work again when wind generator brake removed. This device brake seems to work only when grid goes off. And usually it makes 0-200W, in high winds up to 900W but average wattage is low. Solar panels a lot better. Actually it is same device as solar inverter, may be it is working better with battery setup.

[@Safris1989]

Hi @margusten1 - I plan to buy Istabreez i-1500 as well - in case of similar inverter, would you recommend 24V or 48V version of I-1500? Do you have 1kW or 2kW inverter?

[@margusten1]

@@Safris1989 Hi, I have 1kW inverter. There is written input voltage 22V - 65V. I am using windgenerator 24V nominal. I am afraid that 48V windgenerator exeeding this voltage easily and not working well. Here 4 months no solar and that's why I am using wind.

[@Safris1989]

@@margusten1 same hear in Latvia - short of sun in winter period. I have ordered 24V of I-1500 (0-80VAC output) and was thinking to take the same 1kW inverter, but based on this video it seems that inverter does not like extra V, therefore decided to take 2kW inverter with input 45-90V. Let see how it will go. Thank you for sharing!

[@arjendewaard1352]

I have a gti 2000g-wal connected to a tesup zeus 3.0 (looks the same as insta2000) and have the same problems overvoltage at wind peaks, dumpload switches on. Max output i never seen above 1400watts. Above 7 bft i short the turbine to prevent it will break. In menu i switch dumpload and shortcut off but it still switch to dumpload 🤔. How i connect capacitors to this to buffer overvoltage ? Regards from Holland, cheers Arjen

[@ToysforWatts]

Unfortunately I do not know how to make capacitors work in these systems. I've gotten a lot suggestions to try capacitors, particularly for working as battery banks, but I've never seen a working example.
Mine the dump load is on all the time. There's never any shorting or anything else, the selections in the menu do nothing :/

[@arjendewaard1352]

Dumpload should not be on all the time, mine only switch on at windgust (dumpload is not set on in menu, but still switches above about 100v) . Voltage is fluctuating fast and inverter is not fast enough, so need a bigger buffer capacitor or battery

[@behappymike]

I've sent you a screen shot of my settings, looks like the same inverter. I've also sent you a screenshot of the software version, might be worth checking to see if it's on the latest firmware?

[@ToysforWatts]

I will check it out!

[@liambyrne8248]

Can I have a screenshot shot also please ??

[@pgfox2002]

Mike - I’d really appreciate the same info please. I think if everyone on her combines their findings and knowledge we should be able to get the istabreeze producing properly!! Many thanks

[@tonythoreson]

Seems like a relay is stuck or something and the resistor is too small.

[@ToysforWatts]

I'm pretty sure the relay is stuck/damaged. I'm going to have to open it back up to sort it out.

[@solarandwind9442]

{dave collier} thats his youtube name

[@sundancer442]

Hook it up the batts, not a resistor.

[@ToysforWatts]

If I hook it up to the battery bank it backfeeds.

[@dloman77]

not sure where your water is in relation to this inverter, but this is screaming "make hot water " to me!

[@ToysforWatts]

It's been mentioned a few times...but my house is 120 yards away from my shop. I'm probably going to have to make a large water tank with resistors in it, though, to sit out in the shop...if my plans pan out I'll have close to 10kw worth of turbines up by the end of next year and I'll need a way to dump them all.

[@dloman77]

@@ToysforWatts that could make a very nice thermal battery for the winter! Good thinking!

[@solarandwindinsouthtexasda1473]

No, Chinese company Deye made the original, now it's probably been copied by others. Deye make good quality inverters

[@davidpotter9462]

I would either get my money back or somebody would get bitch slapped down the block. All the way down the block. When it comes to wind generators, I've seen more crap than a sewer plant operator.

[@RC-wu6gm]

Your screen shown at time 13:00 needs to configured properly to match your wind turbine specs.
Your dumpload is triggered when turbine output voltage goes over 60V.
Your shortcut setting of 75V will short-circuit your 3 turbine inputs to stop the turbine from spinning for turbine voltages in excess of 75V.
Your wind curve current settings also appear to be too aggressive for the wind turbine. This video on programming midnite classic wind curves should help explain since your controller seems to work similar ua-cam.com/video/7SRKDaXDZaI/v-deo.html

[@ToysforWatts]

I've tried moving those settings all over the place and it has no effect. The dump load circuit is closed even when the power is off.

[@RC-wu6gm]

@@ToysforWatts It might be designed to be connected to the dumpload with no power to prevent free spin but you might also have a faulty device or stuck relay as you commented elsewhere.

[@RC-wu6gm]

@@ToysforWatts Contacting the wind turbine manufacturers to get the correct power curve would confirm faulty device or bad settings as the cause of your problems.

Does the display come on at all? What's it say?

If you can't see the display then you can't confirm any of the settings...unfortunately there's not much that can be done. If you recently bought it I would take the matter up with the vendor you bought it from.

[@ardehshir4590]

My friend ,when I wiring to my fuse box it show message same as your now even in Heavy wind now my turbine will not run .do you know what I must do with this dam Chinese stuff LOL?

[@ToysforWatts]

So now when it's connected to your grid the display lights up? That's where we should start, once we can see what's going on in the thing's brain then we can start trying to sort out what's wrong with it.
