<html><body style="font-family: Helvetica,Arial,sans-serif; font-size: 12px;">Hi Matt,<br><br>There is no additional data monitoring. I haven't been able to make it out there yet to check the parameters. <br><br>The main reason the client is so worried is that she got a message that I'm not familiar with that said something to the effect that the problem had to be solved before the event light could be turned off. I did not see this personally, and haven't encountered this message before. I will need to see if the manual can shed any light on how to turn off the light. . <br><br>Thanks,<br><br>Drake <br><br><br><blockquote class="atmailquote"><br>----- Original Message -----<br><div id="origionalMessageFromField" style="width:100%;display:inline;background:rgb(228,228,228);"><div style="display:inline;font-weight:bold;">From:</div> "RE-wrenches" <re-wrenches@lists.re-wrenches.org></div><br><div id="origionalMessageToField" style="display:inline;font-weight:bold;">To:</div>"re-wrenches" <re-wrenches@lists.re-wrenches.org><br><div id="origionalMessageSentField" style="display:inline;font-weight:bold;">Cc:</div><br><div style="display:inline;font-weight:bold;">Sent:</div>Tue, 18 Jul 2017 05:56:15 -0400<br><div id="origionalMessageSubjectField" style="display:inline;font-weight:bold;">Subject:</div>[RE-wrenches] Over voltage error message<br><br><br>
Greetings Drake,<br><br>
This is interesting. I have Grid-tied OutBack Radian GS8048A with<br>
MidNite Classic 200 systems in the field, but don't believe I've seen<br>
this issue before. (But certainly have seen many strange MATE3 &<br>
OpticsRE issues)<br><br>
Here are a few questions that come to mind:<br><br>
What is the Radian "Sell" voltage set at? Has this setting been<br>
checked since this issue was reported? Have the Classic 200 settings<br>
been checked to make sure they are set where they should be?<br><br>
Does the system have any data monitoring on the charge controller<br>
and/or battery system independent of the Radian inverter? If so, any<br>
information similar to the Events logged on the MATE3?<br><br>
Does this system have the OutBack FLEXnet DC installed? There could<br>
be more data to review to try and get a sense of what the issue may<br>
be. (shunt data, historical VDC data, any battery charging via grid?)<br><br>
If the system has more than one Classic 200 are they connected and set<br>
up in "Follow Me" mode?<br><br>
Any chance the charge controller or inverter/charger tried to initiate<br>
an equalization charge?<br><br>
Does the system have any DC loads or generation sources (other than<br>
the charge controller and inverter/charger) connected directly to the<br>
battery system or anywhere on the DC bus?<br><br>
Best regards,<br><br>

[RE-wrenches] Over voltage error message<br>

Hello Wrenches,<br><br>
My client reported seeing an overvoltage error message on her Mate 3<br>
on a Radian system. The Radian is selling to the grid and is being<br>
fed by a Midnite Classic 200. It has shown two spikes so far, the<br>
last one going to 67 volts and lasting 1 second. The batteries are<br>
Concorde AGM, 305 AH.<br><br>
Does this momentary spike seem like a problem or a warning of problems to come?<br><br>
Thanks,<br><br>
Drake<br>
