For me, the combiner is a locking boost switch. When the generator is
running, the combiner is combined and the engine is running off the
converter. if the converter can't make the combiner connect, then it won't
power the engine, either.

I have never really needed my boost switch, though I do keep it maintained.
I'm using a 200-amp continuous-duty contactor that I bought from a
combiner manufacturer who had changed their design and surplussed off the
contactors. It's about twice the size of a typical solenoid switch and it
gives a satisfying click when engaged.

But I have have dealt with an alternator failure by removing the wire,
starting the generator, and running off the converter. Worked fine, though
I might not want to do it at night--the headlights, along with everything
else, might exceed the 40-amp capacity of the converter.
