Yes and no.ok thanks.
can you contain and regulate the total draw and final output of the (2) sources combined?
by "Contain" i mean limit... if one source ie the generator starts to increase power, can it draw less from constant to keep the overall total current flowing thru the same?
Power output is not determined at the source. It is the load that determines how much power is drawn from the source.
You mean, can you adjust the power mix so that one source provides a certain percentage of the power? The answer is yes.
