<p>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. </p>

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

<div>Fellow Wrenches,<br>

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.<br>
