This is my new Grid Tie.[attachment=2:1iffvnjt]CTP-500W.JPG[/attachment:1iffvnjt][attachment=1:1iffvnjt]CTP-500WInfo1.jpg[/attachment:1iffvnjt] [attachment=0:1iffvnjt]CTP-500WInfo2.jpg[/attachment:1iffvnjt]I have hooked it up direct and have had it hooked up with diode circuit. The direct connect puts out 30-40 percent more power into the grid. Compared to having it hooked up with the blocking diode. It will kick out and brake the turbine in quick hard gusts till the voltage drops under 24v and try to lock on again. I know I have turbulence here so I am just going to say it. Running a Windtura 500 and 3 35 inch blades at my location. When the grid tie kicks in it draws the turbine right down in 3-5 seconds and switches out till the turbine comes back up in voltage. Above 15 mph it locks on and stays with the turbine. Highest so far is 20 mph wind and everything is working OK. Also they say it needs 30 w solar. More like 50w before it will lock on. As long as there is more than 10.8v DC it will try and lock on even if it is only for a few seconds. I have seen as low as 1.2w back into the grid.
