Morning fellow wrenchers. There is a newer Wind turbine company based in the North East called Kohilo Wind. Link below

They have a 3 and 6kW turbine now but I heard through the grapevine that they may have a 1kW in the near future. Price is a bit high but they are solid machines. https://sd-windenergy.com/ Other folks have been using the Braun turbine out of Germany but that's really spendy. The Whisper line was good, then Southwest Wind Power bought it, they went under, a company from India bought it, then it went to Japan and last I heard it's now owned by a Chinese company.....buyer beware! Although there are a couple of small turbine manufacturer's in the US making 1kW to 2kW machines, I am assuming you want something reliable so you may want to steer clear of those. I won't name names here. And of course there are all those tempting units for sale on Amazon and Ebay....run screaming from the room on those. Slim pickings out there, the small wind industry began a rapid decline back around 2012 when the PV prices started dropping. Most of us wind weanies moved to solar installations to help support our wind habit and decreased wind sales put many turbine manufacturers out of business. Anyway, best of luck on your search and if you find something and care to run it by me off list please do so!

I just replaced blades on one last week and my first install of one of the first ones manufactured in 2001 is still working fine. We took in down about 10 years ago for preventive maintenance and replaced the brushes and blades though both were still in good shape. Most problems have been blades, brushes and a few tower failures mostly due to customer neglect or violent storms. I installed a Pika 1.6 kw at my home about 4 years ago and fell in love with that machine. Pika solved the Blade root attachment weakness found on the Bergey as well as sound issues and performance. Unfortunately they stopped production due to low sales. I ran mine for a year and a half and almost eliminated my generator in a low wind speed site but att he same time saw it perform flawlessly in high winds putting out well over 2500 watts and regulating my batteries at float with no dump loads needed. I got my first order for one and called Pika to order one but they had already stopped production and were not going to make any more. I had sold a customer a complete upgrade of his system which included upgrading from a Xantrex SW Plus to dual Outback inverters, going from 24v to 48v, and directly replacing his Bergey with a Pika, and new Aquion batteries. Sine we had already done the rest of the system, I ended up selling mine to him to keep him happy. I dearly miss that machine. Since Pika sold out to Generac, I’m hanging on a glimmer of hope that the turbine production could be resurrected. Otherwise, the only new turbine I have installed is a 1 kw SuperWind, made in Germany. It is on a 40’ tilt up guyed tower on a mountaintop transmitter site. It has performed as expected with the only problem being susceptible to icing and the blade hub freezing to the nacelle. It is all white so the sun can’t help defrost it. Very nice workmanship but it also has a controller and dump load In addition to pitching blades. Similar cost as the Pika. I don’t have any data on how much the dump load has interacted with the controller. This is a high wind site. I’m not sure how it would perform in low winds. We put it up in November and it survived the winter. If you could find a used Pika, that would be my choice but I haven’t found one yet myself. Let me know If you find anything else. Wind Wrenches out there. ... respond !

Wondering what people are liking out there right now. I know it’s a pretty skinny market and lots of junk but my client would like to replace an aging model that he has in a low to moderate wind area, not spend too much money but spend enough to get reliable. Ideally around 1kW but smaller is ok.
