" I think that's too much current for any charge controller."
Why use a charge controller? Surely the idea is to provide a bulk charge
facility for emergency where the solar resource is not sufficient.
Couldn't you use start/stop control to get the batteries to, say, 80%
charge then shut it down? A simple voltage based controller could close a
contact to start and stop the generator.
