Hello! I've recently been helping out an individual who built the 14' Hugh Piggott Turbine model and he's been having trouble getting close to the expected power output.... It could be a range of factors but I believe the main contributor to it is the power curve settings on his inverter. His invertor is a ginlong GCI-3K-2G-W-US and from my knowledge he has not tweaked the factory settings on the invertor (Partly because the language on the invertor is also in Mandarin). From my understanding from reading different posts, we need a way to measure loaded DC voltage and the power output from the invertor to generate a power curve. I have also read about the use of an onsite anemometer to aid in tweaking power curve settings.

My main and general question is how do we approach the process for collecting relevant data to optimize his power curve? We recently purchased a data logger for the inverter that can track his power output, input voltage, etc. Would this information only be enough? I also want to understand the theory behind this as well so I can generate my own models.
Thanks
