Fronius was good about addressing and tweaked their algorithms (I wish I knew what that really meant…) and the incidences decreased.<br><br>So when I saw this, it brought back memories and got me thinking if Fronius just has a hair-trigger fault process.<br><br>Fronius Primo still the only 240-volt string inverter I can use for ground mounts with 1,000volt rating. Maybe others out there today that I don’t know about but the 15KW and 12.5 string inverter was so important for us in the past.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><img width=335 height=132 style='width:3.4843in;height:1.375in' id="Picture_x0020_1" src="cid:image001.png@01DAADB3.25102FE0"><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> RE-wrenches <re-wrenches-bounces@lists.re-wrenches.org> <b>On Behalf Of </b>Chris Sparadeo via RE-wrenches<br><b>Sent:</b> Thursday, May 23, 2024 7:26 PM<br><b>To:</b> RE-wrenches <re-wrenches@lists.re-wrenches.org><br><b>Cc:</b> Chris Sparadeo <sparadeo.chris@gmail.com><br><b>Subject:</b> Re: [RE-wrenches] Primo with tigos Arc fault issue<o:p></o:p></span></p></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Hi Jeremy! <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>We have encountered this his issue years ago with the AO and Fronius suggested we deactivate the arc fault setting.
