Hi, this is my first post so sorry it is not a contribution!
Anyway, I have a pedal powered business that is doing very well. We use 24v DC Motors as seen here
http://buggies.builtforfun.co.uk/FactFiles/motors.html" . Each motor is connected to the back wheel of the bike (we use a diode next to each motor), so when people pedal it creates about 100w. My question is about wiring. To save time, 3 or 4 of the bike generators are wired in parallel so that we only have one wire per four bikes returning to the charge controller where they all join up. Each bike was tested prior to the event, producing about 5 amps each (we operate a 24v system). However, we found that when all 12 bikes were operated together we only seemed to manage a maximum of 18amps. This was bizarre. I expected to get at least 800w, not 250w.
I hope this is somewhat clear.
So my question is, because we have these generator in parallel motors are somehow cancelling out each other? Is there a better configuration other than wiring each motor back to the charge controller individually?
Thanks for your help!
