<div dir="auto">Wrenches<div dir="auto">Might want to look at the hub and data cables to the inverters, bad or poor connections can effect phases of the inverters, l have seen this manifest it self with errors like inverter firmware issues that in fact are bogus. The OEM cat 5 cables are not shielded and that causes problem when they are wrapped all around in a box. Easy to test with meters, how many times have you just rebooted or unplugged something for it all to get better.</div><div dir="auto">Anyway thats just one of many great ideas </div><div dir="auto">Jerry</div><div dir="auto"> NABCEP Inspector</div><div dir="auto">NABCEP Installer</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Dec 11, 2020, 6:01 PM Jon Siegenthaler <<a href="mailto:jon.siegenthaler@gmail.com">jon.siegenthaler@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hey wrenches,</div><div><br></div><div>I have a client who has a couple of the Radian 8048's and has an error code of "AC Backfeed Error GS-1". Looking at the manual it states that "Usually indicates another AC power source (out of phase with the inverter) was connected to the unit\u2019s AC output.
