While I cannot remember ever seeing this error code, and as you may be suspecting it could do with the; battery wiring either comm or power, the auto transformer either comm or power, or the inverter comm or power. If the owner can get really clear photos and if everything is easy to follow (like different colored comm wires rather than all black wires) then you might be able to see if that is the problem. It could be a bad inverter but it could just be a simple thing that tech support can change remotely. <br></div><div>Side note, if folks are waiting a year for interconnection but passed local inspections, can't you start out as zero export and change once the utility gives PTO? Maybe not but it's worth asking. <br></div><div><br></div><div>Jon<br></div><h1><span class="gmail-subject"><a href="https://www.mail-archive.com/search?l=re-wrenches@lists.re-wrenches.org&q=subject:%22%5C%5BRE%5C-wrenches%5C%5D+Solaredge%5C%2FLG+Troubleshooting%22&o=newest" rel="nofollow"><span></span></a></span>

<pre>Wrenches,
I received a call from a person who is having issues with his Solaredge/LG
system. He\u2019s got a SE7600A-US, StoreEdge connection unit, autotransformer, and
LG battery. I\u2019ve never laid hands on SE or LG equipment and could use some
guidance here. He\u2019s located several hours from me, and I\u2019m the only Solar Bozo
around>
His Words:</pre><pre>Happy Saturday Michael, thanks again for taking an interest in my solar
situation. In June 2020 my 9.920 KW (15,752 kWh estimated production) solar
system was installed by now bankrupt "Empire Solar". Thirty-one (31) 320W
panels were installed on my roof. My system included a battery back-up system
which utilizes an LG Li-Ion RESU10H battery (model #R15563P3SSEG).
Unfortunately, more than a year passed after installation for a net metering
agreement (NME) with Pacific Power to be put in place. Pacific Power installed
a new compatible meter on my home the same week I learned Empire Solar filed
for bankruptcy. Empire sent me an email with easy-to-follow instructions for
turning my system on. I followed the very simple instructions with zero
results. Pacific Power since confirmed my system is not generating any power.
Currently, my "Solar Edge" inverter displays error code "2x1A - Faulty AC
Relay". The inverter cycles through a 5-minute "wake-up" routine in which it
counts down from 300 before it displays the aforementioned error code, then
begins the wake-up countdown again and repeats this cycle endlessly until I
power off the LG battery.
Thanks everyone
