I did alot of warranty for SMA and fronius with arc fault breakers and
their central inverters. Way out in the boonies where few would go fro
service. It was always the Arc breaker.
I do not know how Midnite Rosie is designed. Ask them? Good luck. I
assume the Arc fault needs to be there? Might be a hard decision if the
panels are on a roof to bypass.

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.
