[RE-wrenches] Little Rosie vs Arc Fault Breaker?

[Kent]

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.
