<div dir="auto">William <div dir="auto">Sounds like the inverters are in search not on, have you changed the inverters to on instead of search. Have you considered a hard reset to factory. Also as a POE (process of elimination) I would turn off one of the slaves at a time, even switch over to a different master. I had a 16 kg in Hana that after 2 years started doing that kinda issue, it ended up be programming issues, why? dont know but it can happen. I just did a new mate 3 software update and it scrambled all the utility settings so keep notes of everything that you ever change just in case</div><div dir="auto">Jerry</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Sep 3, 2019, 6:06 PM William Miller <<a href="mailto:william@millersolar.com">william@millersolar.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Friends:<br>

The message below never got posted to the Wrenches list. I don't know how<br>
the list works but sometimes there is a quite a delay.<br>
<br>
I am still in need of advice. The problem went away mysteriously and then<br>
came back. I can make the problem go away by unplugging the data cable to<br>
inverter 3, but this can't be a permanent fix. Outback has not a clue on<br>
what is going on...<br>
<br>
Any help is appreciated. This problem is causing me a headache and a<br>
black-eye....<br>

We have a 3 stack Radian system installed about two years ago. The<br>
customer had some health issues and is just moving into the new home.<br>
<br>
Over the weekend the system started strobing the AC output. One or more of<br>
the inverters was clicking and buzzing.<br>
<br>
Tech support diagnosed a faulty setting for power save. We adjusted as<br>
recommended but problem persists.<br>
<br>
On site, I found the clicking from transfer relays and a pop-buzz from one<br>
or both power units on inverter 3. When I unplugged the data cable to that<br>
inverter the noises stopped.<br>
<br>
The inverter data cables are all new about 2 months to resolve the<br>
dreaded firmware mismatch problem. They are not shielded. I tried a new<br>
factory shielded cable on 3 but problem persists.<br>
<br>
I have been holding all morning for tech support. BTW pressing 2 for<br>
call-back does not work.<br>
<br>
Any help would be appreciated. I am stuck on site until this is<br>
resolved....<br>
