<p>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.</p>
<div id="signature">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.<br />

<div class="pre" style="margin: 0; padding: 0; font-family: monospace">Fellow Wrenches,<br /><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 /><br />Kent Osterberg<br />Blue Mountain Solar<br /><br /><br />_______________________________________________<br />List sponsored by Redwood Alliance<br /><br />Pay optional member dues here: <a href="http://re-wrenches.org" target="_blank" rel="noopener noreferrer">http://re-wrenches.org</a><br /><br />List Address: <a href="mailto:RE-wrenches@lists.re-wrenches.org">RE-wrenches@lists.re-wrenches.org</a><br /><br />Change listserver email address & settings:<br /><a href="http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org" target="_blank" rel="noopener noreferrer">http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org</a><br /><br />There are two list archives for searching.
