WORTH Buying? Powerful Wind Turbine IstaBreeze i2000 Windsafe with controller . 

I bought the IstaBreeze Heli 4.0, wish I didn't. Quality wise not good and lasted a year without never producing power as promised, and now it isn't working any more.

@@ToKa.Cyprus what's wrong with it?

@@ToKa.Cyprus Plz tell why. Because of no wind in your place? 😂

Do you have any videos up or are you on any platforms where you can share more info

Germany doesn't produce reliable products for a long time.

Hallo, 10monate sind vorbei , und wie ist deine Erfahrung damit ??? Bitte antworte . Danke

How is it?

Any video data on it?

Toys for watts also got some 2 types of istabreeze and they perform the best.

I think it makes max power at 30mph so this gust has to be like 40-50 to see a spike like that and yea it's crazy to hear the hardware store swear a cable can only carry so much current then you see this... wonder if he would have seen an even larger spike had his wire been thicker 😮

The meter is connected between the output of the controller and the batteries www.windofkeltia.com/eagles-view.org/solar/images/bayite-display-2.png instead of the displayed battery, connect the output from the controller and instead of the displayed load, connect your batteries

@@kukomio Thank you very much !!!

@@kukomio Hello Sir, I need to get back to you with another question about the VOLT/AMP meter. I connected the meter to the wind turbine controller. I have the simpler version of the controller, not the one you present in the video. It is the model with the red big rottary button for the brake on the front panel. So my question is, the voltage displayed on the left upper corner by the voltmeter's display is the voltage produced by the wind turbine ? Because my meter currently shows the battery voltage, when the wind turbine is not spinning. I just need to confirm that I connected the meter correctly. Inside the wind turbine controller I only have access to the 3 phases wires from the turbine, the solar panels connector, and the battery terminals connector. Thank you in advance.

yes, it is connected correctly, the meter shows the battery voltage

@@kukomio Thank you for confirmation, much appreciated Sir !!!

Use Omni calculator (HAWT) to back calculate the likely windspeed based on the blade diameter..... you can't generate more power than is available at any given wind speed, based on it's claimed rating I'd say about 14/ms which is gale force and will only be available about 2% of the year 🤔

Okay

If you have steady 11m/s or 25 mph winds then you can estimate how many kWHrs you will generate. KWHrs = Hours x 1.5 kW

Come along or hand winch

I'm trying to figure out the same thing only with eg4 inverter/charge controller all-in-one

I have Ista Brezze - 2000w 48v, without any problems www.ebay.com/itm/153658953614

@@kukomio Hi. I noticed you used different controller in the video (HWS2KW-48V), did it fail? Is this controller better?

This regulator is set for 48v lead acid batteries, but if your battery has a BMS system, you don't have to worry and you can connect it to li-ion/lifepo4 batteries as well

A 48 V battery bank has to go to at least 14.5 V per battery For the bulk charging cycle, so that’s 58 V then sure when it gets too float mode 54.4 is good but one thing I have learned by installing solar systems is that every single system I have tested even the ones I have not installed we all have the same problem, The specific gravity of the electrolyte in a flooded cell battery slowly diminishes within a year it drops a lot eventually the batteries go bad because of this. Why? Because it seems that none of the charge controllers even though some of them say they do a equalization charge once a month or so does not gas the batteries at a higher voltage for a long enough time to get there battery acid concentration level up to the 1.275 fully charged level. The controllers will see the voltage and stop charging the batteries based on voltage they don’t see the acid concentration level so when the voltage reaches the correct voltage it stops charging the batteries and goes to float mode and the acid never gets to the correct concentration level. The acid concentration level gives you your reserve capacity of the battery battery voltage is almost meaningless it’s the acid level that tells you how much power is in the battery so what I have to do is like once a month or so I have to manually charge the batteries for a longer period of time at A voltage where the battery is gassing until the acid level gets back up to the 1.275 level. I have found if I don’t do this eventually the capacity of the battery diminishes the voltage will always say the battery is fine but if you do a reserve capacity test On it it will not go the minutes that it is rated to go

So what do you suggest ? Is there a good solution ? I had lead acid batteries and now I switched to LiFePo4 , which are better ? In my amateur observation lead acid were good but they took a lot of space , I never had any problems in 7 years. Now i have lifepo for 1,5year only had problem one time when they lost voltage rapidly because there wasnt sun for period of 2 weeks . Now i have ista breeze with this controller and step up converter . The turbine is really good but i think there should be a constant converter inside controler that should deliver constant voltage , what do you think ? Oh , should mention that the system is off grid? I am considering to switch to rack batteries in about a year.

@@rmendes2mendes915 Why are you still using lead acid? Get LiFePO4 with a proper BMS. Problem solved.

I'd say if you had the inverter close the to wind turbine you can run long distances l. Less losses with AC over distance

turbine puts out AC power so you can run it a long distance with minimal losses over the correct gauge of wire. You need the charge controller to turn it into dc power suitable for the batteries.

Ahoj, táto turbína je konkrétne na off-grid systém, čo mi aj veľmi vyhovuje. V zime silnejšom vetre a náhodou výpadku elektriny bude v dome fungovať elektrina, nakoľko mám k tomuto systému (3kW solárne panely + 2kW veterná turbína a menič 4kW) batérie 10kW. Ale konkrétne čísla o úspore a efektivite budem môcť povedať až o rok. Skúšal som už tri veterné turbíny, ale zatiaľ tato jediná neklame o výkone.

@@kukomio co máte za měnič? Jakým způsobem nabíjíte baterie? Mohl by jste prosím zahrnout do sumárního videa výhodnosti, také komplet vaší instalace? Díky

In colder weather, the generator cools more so that offsets its extra heat from running over spec. But the gauge of your wires may be a concern, as that heat may not be so readily removed depending on how the wires are routed to your house, and your wires may potentially be underrated for the current. Another concern is the voltage of the wires, as the RPM increases so too does the voltage, so your voltage is above spec and that may be an issue for the rectifiers (check their rated voltage) and in general safety since higher voltage can arc further, heat may also be an issue for the rectifiers if they are indoors but gusts are probably short. And lastly running faster than design may cause excessive wear on the bearings in the generator, but that's hard to quantify. Theoretically the system should protect itself by swiveling like it does during a storm, but this movement may not happen quick enough in a gust to mitigate any risk of damage. Unfortunately I can't give a definitive answer as to whether gusting to 3 kW will damage any electronics or start a fire, as there's just too many variables.

I made the mast where the winch is by myself Hand winch amzn.to/3SkjRID profile 100 x 60 x 3000m stavex.sk/produkt/profil-joklovy-100x60

I think both are good, it depends on what power you need, I have 2000w and I'm satisfied.

2000w is best

the problem with the controller is what you have

The generator is a 3 phase alternator, therefore 3 wires. When you connect 2 wires, only one phase is connected and puts a small load on the generator. When the third wire is connected, all three phases are now putting a load on the generator and would require a wind speed 3 times as much to spin the generator at the same speed.

Never buy chinese stuff. All fake and made from slavery

You did not see the PRICE at the ISTA-BREEZE website ???

istabreeze.us/40-kg-mast-tower-set/

It's not grounding, I just used such a cable

It's a single-phase AC-cable used for three-phase.

@@kukomio Thanks! Can you also tell me which screws you use for mounting the flange on the top of the Mast? My Set doesnt include any screws... @3:07

Mine was also without screws, this is what I had at home. T-screw M10 x 25 www.solar-eshop.sk/p/sroub-m10-x-50/
