Running two turbines in series

    So if my wiring off the two rectifiers were wired the same as I would with 2 12v batteries to get 24v,, the turbines would double there volts and only put out 1/2 amperage..

    I am seeing with a large battery bank(48v) and the new 2kw gen head that the ouput sucks because it stays locked right around 25 v.. I would like to be in the 35-45 v range most of the time and wanted to try the 2 500 in series and the 56v 2kw connected to this merged voltage... In theory I should help slow down the speed of the 2 in series with a load at a lower voltage but still help puff up from 25-say to 45.

    Locked into this small window of voltages sucks and am thinking of a larger 22-60v bank and instead of the 24v 500's bringing down the 56v effsun I will do the opposite..

    Input??? It needs to be tried, I feel we can unlock more output and less line lose by a higher working voltage..

    Does anyone know of anything that we could put into this system to GUARENTEE no over 60 volts..Something that will blow a fuse or shut the current off.

    I love the idea of a new charge controller that uses a small amount of current to trip a heavy duty relay and keep all these amps out of the unit itself..I am on a 3rd coleman air 160 amp my ass..

    Well finally hit the 300 watt range a few times today. With the two turbines the grid tie is better behaved than it was before. Instead of sitting at 11-12 volts it has climbed to 13-14 volt range for most of the day. I figured with the gusts it would kick the switch and dump. But it has not so far.

    Now I kinda understand why you are frying grid ties. My 10.8-30 volt and 22-60 volt grid ties both took a 5 sec break at the same time. And went over volt. The switch tripped the relay for the dump. Never thought I would see that happen.

    Tom I fried my whole 22-60 bank with amps that not only fried the fuses but started to melt the posts.. One grid tie malfucntions so bad that juice flowed back from the grid sparking and tripped the breaker..

    To many turbines connected for these entry level grid ties.. I wouldnt recommend more than a true 1kw on these no mattery the size of the bank.

    Well I am still waiting for that 600 watt to show up. I will be running mine as is with the 600 watt and the 300 watt when it arrives.
    That is why I have that switch hooked to dump at 30 volts now. If either grid tie fails or the power goes out it will dump to the dump load at 30 volts.
