We seem to have the power curve pretty well dialed in now.
I might of known that was premature. I don't know if anyone else has gotten the winds we have in the last few days, but it has been wild
here. Yesterday the temps were -17F in the morning and never got above 4 to 5F all day. I mostly watched, and tweaked our turbine when I wasn't feeding the wood stove. Then there was the wind. Steady in the 15-20 mph range all day yesterday and last night; gusts around 45 mph. Today they were a bit less, but steady all day long.
On Thursday we logged a high output of 3,760 w on one controller and 1,064 w on the second. The Classic 250's have a max current rating of 62A at 25C; derated current is 52A at 40C. The fans are non-programmable and go ON at 48C; Off at 45C. I had the current limit set at 42A on the fist unit. I know it is only briefly at the 'max output', but it is just too close for my liking. It comes up fast with the right gust (unfurl, yaw..and bam). I loaded yet another power curve (I'm on MEM6 now), this one has the current limit at 40A, and the second unit is set to 'wake' earlier, and load more.
I'm anxious to see what it recorded today - which won't post until midnight - but yesterday we had similar overall output, but the first unit held at about 2.8 kW, and the second one grabbed just short of 2 kW. I wish they allowed the two controllers to share equally, but they never pursued this firmware option.
The furling performed really, really well. This was probably the roughest sustained winds that we've let'r run through. At times it will fold and stay there through a pro-longed high point, or stay at near full-furl position 'til it subsides. I'm fine with this.
