No it starts at 4 mph and I get output at 6-7 mph at 10 mph it is at 50 watts. My wind meter has been at 0 mph for almost a month here. Even when the storms come thru I am at 0 mph here and 10 miles away it was gusting to 50 mph. My weather report comes from Jefferson,Ohio. A storm just went thru south of me and top wind was 12 mph here and was putting out 70 watts. But the trees do have all their leaves. Someday I will get the turbine up to the better wind. In the last 25 days I have only gotten 1kw wind. Solar is at 15 kw. Today is the second time this month I have gotten any wind here.
Just started to get some wind again. PHEW.......Solar is at 20 KWH a month for the past 3 months. Wind at less than 1 KWH a month. What little wind we have had started coming only out of the SW right thru a tree.
New roof mount for the 600 watt PMA. The blades are TLG hub with steel extensions and Windy Nation 30 inch blades. (UPDATE) TLG hub with extensions didn't work well. This is all I have laying around so I will go with it for now. The steel for the top portion will be here in two weeks.
Here are the pictures of that 300 watt turbine. It has been running almost none stop from wind coming up the valley of the roof. Second picture is of the modification to the mounting system to anchor it to the roof. The roof drops down on the back half. It tracks better than the other one and rotates alot easier. (UPDATE) I changed both mounts to the way I changed the Effsun PMA. They are easy to make and cheap. Just bend a 90 Degree Angle and mount tail on with small u bolts.
So far so good. Just getting a little wind around here and so far a big improvement. Watts jump up and stay there. The wattage does not quickly fall off anymore. Voltage rises alot slower with wattage increase on the Grid Tie.
Thanks....I am now wondering if the noise reduction is because it is using two teflon washers for the yaw bearing and / or the new design of this turbine from Effsun. It does not make any noise like the other one. Basically I can not hear it at all. I also used a different plate for now for the nose cone. No 10 lb weight this time.
I am still working out how my two pmas will work together with grid ties. Had just one gust all day and it took the 10.8-22 volt GTI and ran right past 30 volts but the 22-60 volt GTI did not pick up the rest. I also did not go over 40 volts or the dump would have kicked in. I have a red indicator light on it. So I would know if it dumped. Waiting again to see what happens next time.
35 volts and it will pop..It will happen to fast for the 22 to lock on before its 2 late.So your batteries need to be bigger to stop the voltage climb in fast gusts if they are just a dummy load and cap...The smaller the agm battery the less load voltage cap you have..welcome to multiple turbines.
Well it took two wind generators but I now seem to have a good match for the SunG 10.8-30 volt 500 watt wind GTI. (UPDATE) Just remember GRID TIES are current hungry. I have alot less over voltages and it holds to a wattage without dropping till the wind does. No more spin up and quick slow downs.
Thanks Tom, Yes, running them (2 turbines rather then one) in paralle with one or two GT's will keep the over volts down. I have found it is a give and take. Doing it that way you loose your power in the mid range winds but gain more constant low wind watts. In higher winds you can get all the power. This is why i use a 250 and a 1kw. In my situation(6-20mph winds) i want to get to 22v in about 15mph winds runnig through the 250 and letting the 1kw do the rest as well as running the turbines at a higher volatge. The problem is if you run 2 turbines into a 250 and a 22-60 GTI the two turbines keep a better steady voltge and the 250 or a 500 (10-30v) does not want to let it go in mid range winds. I seen 220 watts out of the 250 doing it this way and i was affraid i was going to fry it due to the amps going in. So i am back to ea turbine on it's own system trying to get through the 250 as soon as i can. The 250 gives me the low wind speed watts so i does well with one turbine . For higher wind area i do recomend just using 22-60v inverters only. I have also addd caps to each rectifier. They seem to work pretty well. Letting the turbines spin just a little longer for an easier start up for the next gust as well as smoothing out the volatges. Again for my site i want to get through my 250 GTI to get to 22v or more ASAP.
Being my average winds are never higher than 15-20 mph. I have seen that the 22-60 volt GTI does not give me as much watts as the 10.8-30 volt GTI. Also could be from the 5 blades holding it back in higher winds. But since that is not all the time just for a few seconds at a time it is not worth it. But it is good as a team to get some of the watts and keep the voltage level down. Even with the battery tie it does not get to 24 + volts very often. From what I have been seeing the GTIs seem to be more interested in keeping current down than voltage. So the best advise I can give is see what you are getting in average winds. Buy a GTI for that wattage and make sure you have over voltage protection. If you get big short bursts of wind.

Here is what I am going to use to change over to the 600w turbine. It came with the bolts in the picture. They only had 4 threads after the nuts on the end. I used 5/16 threaded rod and welded 1 inch long nuts on the end to make new mounting bolts. I also had to grind the high spots off about half way up the nut . So it would fit down in the holes. The bracket is 6in by 12in by 1/8inch bent in a 90. I will have to cut the old mounting bracket off and bolt this one in its place.
The Windy Nation 500 watt. It will be coming down for testing and inspection. The 300 watt is doing well and has seen over 400 watts at 30 mph. Here is a better picture of the mounting plate and bolts.
Got it up today. After breaking two saw blades went with a mini grinder to remove the old mount. It is a little tight so will have to wait a few days for some wind to loosen it up.
With those blades what rpm do you think it will hit at 25mph? WN has 60-inch on there Rover; not sure if their PMA is identical or not to the one you have.
I would have went with Windy Nation 5 blades but I am out of money. So these will have to do till I can afford them. As far as rpm I have no idea. I will post more info when I have wind. The rover PMA is a smaller unit than mine. The Effsun 300, 840 rpm,400-840 rpm,500-840 rpm and 600-560 rpm watt models are all the same except for the length of the unit. They are on sale at aliexpress . They give info and dimensions of the units there.
