What if....

So, people have asked in various posts on different forums:
-Can you hook up two enphase micro inverter inputs in parallel if you have a larger source than a sole microinverter can handle?
And I'm curious:
-What if you hooked up an MPPT charge controller in parallel with an enphase microinverter?
Seems like inquiring minds want to know. At least I do. Anything out there that anyone can point to where these have been tried?

When you have two or more MPPT input controllers, they will each be drawing current and monitoring voltage--And since the "other MPPT's" current draw is "invisible' to its "mate", they will be gathering faulty data, making faulty assumptions about Pmp=Vmp*Imp, and probably "oscillating" each unit's current draw as they try to hold (calculated optimum) Vmp voltage.
Will is "damage" the controllers or the energy source--Probably not--You can try and see what happens. There are lots of variations in MPPT algorithms, so different brands/models may play differently with each other.
An analogy... Imagine a car with two engines and two gas pedals... And two people controlling the pedals (or two "cruise controls") and not knowing what the other is doing... Trying to hold 55 MPH, up/down hills, wind, etc... It would be difficult to control a steady speed that way.
When dealing with Grid Tied inverters... There are "transformer-less" models that would damage (for example) a MPPT solar charge controller in parallel with a "Transformerless" GT Inverter. Transformerless GT inverter solar inputs are not "ground referenced" (as I understand), and they will probably "fry" a solar MPPT charge controller.
