There are issues with some combiner boxes, when the fuse holders are
opened under load. The current can (reportedly) make a continuous
arc across the contacts. This is true for the higher voltages, for
grid tie inverters, and would be true for AC coupled off grid
systems. Maybe 100 V would not be an issue.

That is, if you put the screw in! I approve of the new Outback
combiner that is equipped with a dead-front.

William,
I believe most combiner boxes don't qualify as a disconnect device
because it takes a screw driver to open them before you can turn anything off.
