When my 15 year old Air 400 started having problems I decided to upgrade. The Sunforce seemed to be a good product at a good price. The generator was erected on the same 30' pole that the Air 400 had been on. Everything was basically the same except for the upgrade of the controller that comes with the Sunforce (that's good) and 200 more watts of power. In winds of about 25 mph the Sunforce seized within the first 24 hours of operation. Northern Tool replaced it with a new one at their expense including shipping both ways. Thanks Northern Tool. The new generator was erected and seemed to be doing good in winds of about 25 mph until the fourth day. It seized just like the first one. Call Northern Tool again. They decided to refund my money and, again paid the shipping to return the generator. They are great. I wonder why they would continue to offer such an inferior product. I am not new to this industry. I have lived off the grid for nearly 20 years and have designed and installed my own systems as well as some for others. They work as they should. I know something that doesn't work properly and this generator is one such item.
First you are crazy if you do not buy this turbine at this price! . mine are 3 years old and still kicking like new! It beats missouri freedom output and start givined watts in low winds...while the other turns and give nothing. I recommend for the serious solar and wind person to use it without the mppt and use a rectifier instead if you have a "dump load"...any excess in mine goes to heat up my hot water. I recently purchase a freedom 2 and it is not match for my two sunforce 600 ...it comes close at high wind. I recommend using turbines with solar panels..solar panel will beat wind any days! Only people who do not understand will complain about this turbine...may be they do not have enought wind and expect miracles! at this price I am even considering buying one more! The design is excellent...no rain can get in.! I bought simillar turbines before looking like the sunforce and they where all junk! So trust me...this one is the best if you have wind! Another idea for newbies for your dump load is to by resistors that works like a space heater...that is if you have lots of wind. I recommend colleman charge controlers they have a dump load feature.
I only got this installed a few days ago but it is working nicely so far. Delivery was very quick. I pinched a wire my first try but found and repaired it. Manual good, but I would like more info how the MPPT controller interacts with a separate solar array with its own MPPT controller. I just don't see how to tell which takes precedence, but it both seem to work even without my understanding.
I have set the wind generator up at my house and it is keeping my batteries charged up great. I have a D.C. frig.and it is running all the time and a R.V is also running off the same batteries. It was one of the best investments I have made for a auxiliary power source. The next time my power goes out I will not have to worry about getting gas for my old generator.I am very pleased with my purchase.
Hi I found this to be a very good product however you must take your time and do everything according to the manual and code. The pole must be securely installed i used schedule 40 pipe 2 10 feet pieces and cemented it in the ground with 2by6 pressure treated fastened to the studs and fastened to the pipe with a threaded flange on the 2by6 and t fitting to the pipe i used marine 3 conducted #10 wire. Customer support is very good and it has a 5 year limited warranty. I spoke to customer service and they advised me not to connect the the inverter load side of the battery controller and it performs better. Just take your time and if you need help contact customer service. I have two you tube videos look for jerrys coleman wind turbine and jerrys coleman wind turbine and solar power. sunforce and coleman are now together.
I purchased the turbine and the rectifier / charger assembly fried within a few days of installation. I returned the turbine and got another. It died with a siezed main bearing within a few weeks. I got another from Sunforce and it, too, died with a siezed bearing in a few months.
Putting up a turbine is not a trivial effort; this poorly designed unit caused me three installations without satisfaction.
After purchasing and installing this unit I found the MTTP controller was malfunctuning. Sunforce replaced it at no cost. After using the turbine at my camp for two weeks hooked to my battery bank while I was gone there was no gain whatsoever in my batteries. The power inverter is turned off when I am gone so there is no draw and still the batteries did not charge at all. We had plenty of wind over the two week period and I expected to come back to camp and have my batteries topped off but there was no difference in voltage since I left. I had to start the generator to recharge the batteries. I have run a multi meter on all parts of the system and everything appears to be working but this system is no better than a battery maintainer. I think it would only be good for keeping and ATV battery topped off. For that my 15 watt solar panel works just fine for far less cost. I wish I would not have wasted the money on this and just invested it in solar panels. That is my next step, to increase my solar charging ability. I thought this would be a great addition. NOT!!!!
I put this up and within minues it started turning. I looked at many wind turbines, and for the price and simplicity of this one, this is a far better choice.I have solar and with the directions, it makes it so easy to instal. I added a little paint to mine and it looks great, very impressive and my neighbors love it too. Very quiet and when it is spinning fast, it is still pretty quiet. I think I made the right choice.

"I figure to get 600 watts you need a wind speed around 30-35 mph.
For a more typical 10-12 mph wind, expect around 15-25 watts.
5 mph gives 2 watts; just enough to turn the rotor."
