Green on the graph is the wind speed and yellow is the power out. You can see from the graph that high wind does not always = higher power out. It seems the sweet spot is 8 meters per second.

Windview software
People have asked about the wind view software. Originally, it didn't do very much but now that the inverters are attached it is getting more useful. You need to run it from a Opera web browser. It will not run on ie8 or ie9 but will run on an iPhone. We were able to restart the turbine when we were away on a windy weekend. After the wind turbine shuts down from over wind it needs a manual restart, which we could do from an iPhone.

November Results
This month we’ve had a few issues with the software. It has been having errors in low wind and doing a lot of extra yawing. We’ve had to unwind it twice. Not huge issues but we missed a few hours of wind here and there when we were sleeping or away. There is a new version of software that should fix these low wind issues, but we were not able to get it to load. We’re hoping a tech will come by soon to upgrade us. With the next version of software, upgrading will be able to be done remotely they say.
This month we had a total of 286KWH of power. The average wind speed for the month was only 5 miles per hour.
Other news this month – I’m glad to see that NYSERDA still has Redriven listed as a choice. The more turbines they have in NY State the more access we will have to the technicians.

October a Record Breaking Month
Another record broken. From Sept 27 to Oct. 27 We produced 408 KWH for the month. Average wind speed was 6.3 mph. The inverters recorded that they produced 529KWH for the month. Also, we have been running without an outage since July!
Last Sunday Scott from Redriven was here and upgraded our system (Nacell, long board and HMI to version 3.34.
This was not a big upgrade. You can now get live wind speed on the main screen . The new software has Internet connection capability again. The main screen now has RPM, MPS and Degrees. It also had better error handling so there will be few times when it completely shuts down based on faults alarms. We've had it for 6 days and so far it seems better than the last code.
