Hi. My new blades ate 81 cm and the same problem. Turning clockwise and I had to make a metal extender of the shaft. On. The end they need wind of 3-4 m/s to start turning.
hm. well, such slow start rather means - they are having not enough starting torque earlier, and that your gen is more powerful than the wind wheel. go for a bigger diameter if possible, 2.0 or maybe 2.2. My 0.81 blades hub (1.65 dia) works well with starting at 1.5 m/s already on the smaller generators.
@ in my place is a lot of buildings around and the wind is not consistent. When I move my turbine to the place where we building our new house there will be top of the hill so hope will work well. But thinking to get blades of ista breeze. What do you think ? My turbine is 1 kw 48v
no-no. Ista has got awful blades, don't even try... thin, very bendy (tend to bend on the wind heavily), very slow start (5 m/s approx). only unless you are going for their fiberglass blades used for Heli - those are the ones to be likely decent ones. what wind turbine do you have? maybe it's just better to invest in a proper wind turbine? for example, my 2 kW 3.2 diameter Chinese FT-2000L2 is matching and even outpacing the promised specifications, and I have not the best wind conditions as well.
@ I thinking of changing blades the original 55cm was performing better in the strong wind. Is so much problem to get some of good blades. I will try to take the turbine next week for testing in the lot where is on top with no obstruction
