So the intended application is a spin bike generator - so a 3 phase brushless ac motor (from a skateboard) run off a flywheel of a spinbike with the intention to charge a 12V lead acid battery.
Input voltage is expected in the range of 20 - 40V dc (via a 3 phase bridge rectifier). Don't expect any overvoltage as the flywheel will keep the speed and hence voltage in check.
Will the unit handle the input? I calculate input is likely to be below 200W so shouldn't be close to the 290W max. with a 12V battery. I can't imagine any overspeed, hence overvoltage scenarios like might be the case with hydro generator or combustion engine generator
Battery charging: I'm assuming once the battery is full, will the controller autoamtically ramp up the impedance to reduce current drawn from the generator. (I assume this is how it reduces current drawn form a solar panel?) i.e. Pedalling will become easy
If the battery is very low charge, then I assume the controller will try to draw more current from the input - so pedalling will become heavy.
Does this sound reasonable or have I missed something?
Reason for using the MPPT controller is that I might use a solar panel later as an alternative input
