We're seeing multiple inverters with the same error, and not getting the best of answers or support from SMA on fixing the problem so far. &nbsp;And this is not a metal roof; it's PanelClaw on EPDM.

<p class="MsoNormal">Friends,</p>
<p class="MsoNormal">&nbsp;</p>
<p class="MsoNormal">We have run across an odd technical problem at our commercial install at a laundromat on our island. &nbsp;&nbsp;Attached is the description of the issue from SMA. &nbsp;We dont know much except that we are switch out the TL inverters to the old style
 US inverters because SMA has no fix for the phantom ground tripping. &nbsp;The issue is beyond our feeble understanding. &nbsp;</p>
<p class="MsoNormal">&nbsp;</p>
<p class="MsoNormal">Any observations to share?</p>
<p class="MsoNormal">&nbsp;</p>
