No, nyt kävi niin, että pitkällisen harkinnan jälkeen tilasin tämän:

Tuosta vehkeestä kannattaa pysytellä erossa. Turkkilaista *askaa.

Eli turhaa korotat mastoa. Et tule koskaan saamaan yhtään ampeerituntia akkuihin. Mutta tämä taisi olla jo tiedossa kun vehkeen ostit.
"Dear Ista Breeze UK,
I am writing to you regarding the 24v Ista Breeze wind gen that I purchased from you a few weeks ago. To be honest I'm very disappointed with it's performance.
I have it mounted on a 6.5m pole, on the roof of my narrow boat which is approximately 2m high; 8.5m in total. the power curve and promotional material that relates to the generator states that it it's start up speed is 3.5 ms or 6.8 knots. In fact the blades don't even begin to turn below 15 knots, nearly twice the figures given.
The power output is also way off, The unit claims to produce 100w at 5m/s and just above 500w at 15m/s; this is nonsense. I have observed a maximum amp input into my 24v system of just 6 amps, and that at the point at which the blades stall. Even when the blades have been turning rapidly I have recorded voltages at much less than 24v, that's not going to add anything to a 24v system and only watched the volts rise to 30v, briefly, at blade stall. I connected the generator to a 12v system, temporarily, to see if I'd been sent a 12v model by mistake but still saw only 10 amps recorded at stall speed. That's just 144w, nowhere near the 500w that the generator is 'rated' at.
During some pretty strong winds here a couple of weeks ago the generator clocked up just 3.7ah into my system over the course of the night and next morning with batteries at only half charge, which is woeful.
I have had a Rutland 913 wind generator fitted to my yacht for the last 6 years and always had good results and no trouble from it. The blades fitted to your Ista Breeze unit, when stalling, make the most horrendous concussive roar, like nothing I've heard from a wind gen before, and as a cruising yachtsman I've seen many. It is so bad in fact that I've had to take the unit down for fear of upsetting my neighbors.
One of the knurled knobs on the rectifier/controller fell off the brass nut when being tightened, finger tight. I am not impressed with the build quality of that piece of equipment either.
I have tried to contact you on the number given on the sticker that was fixed to the controller but that got me through to a wire stripper supply company. Eventually I was able to contact your company by telephone, and did so twice with the promise that someone, when available, would get back to me but this offer was not forthcoming on either occasion.
I don't believe that the product information or claims about it's performance or output are true or correct. The unit is therefore useless to me and I respectfully ask that I may return it to you for a full refund.
Please advise......"
