It is the inverter that trips off not the breaker and nothing needs to
be done to restore power except to reset the inverter. It isn't unusual
for an inverter to trip off due to overload faster than a breaker
responds. But I wouldn't expect the inverter to trip off due to an arc
fault.
The electrician has been out there twice looking for a problem with the
wiring and found nothing.

Maybe it’s a real arc-fault in the system somewhere, and the breaker
is trying to tell you that.

Fellow Wrenches,
I have a system that we installed a few weeks ago that is driving us
crazy with overload faults. It is a remote cabin with maybe a half
dozen circuits being fed by a Little Rosie inverter. Every couple
weeks the power system shuts down with the Little Rosie showing an
overload for no apparent reason. Client resets the inverter and
everything runs fine for a couple weeks or so. The system seems to
have no trouble when the Arc Fault (a Siemens arc fault breaker in a
100-A Siemens panel) breaker is turned off. Any of you have similar
issues with these breakers? It is weird that the breaker could
actually be causing the inverter to trip off.
