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..
