This one is kind of unusual... Especially tripping only in the
morning.<br>
<br>
Temperature ? Something moving or shaking the breaker box ?<br>
<br>
Have you tried changing the circuit breaker ?<br>
<br>
What is the approximate maximum current output from the Classic in
the morning ?<br>
<br>
You can access recent power info before the trip in the LOGS menu
or the main status menu by hitting<br>
the STATUS button a few times... Four hits I think, until you see
the graph of power vs. time show up.<br>
There are other items logged and can be seen by pressing the UP
button. Logging is done around every<br>
5 or 10 minutes and the most recent log will be on the right side
of the graph.<br>
To move the cursor to the right to get this value, press the RIGHT
arrow key. LEFT key moves it<br>
backward in time and right to more recent time. If the MNGP
(display) time and date is set correctly,<br>
the logs should present the actual logging time correctly.<br>
<br>
The daily logs won't save the maximum power data because the
Classic will reset before that info is saved<br>
when the breaker tripped. That usually happens at midnight.<br>
<br>
I know you don't usually get the nameplate rating out of an
array but 18*245W adds<br>
up to 4400 watts or so and would be around 90+ amps at 48V if it
should ever<br>
put out that much power.<br>
<br>
This list is going to have some great ideas but if we can also
help, give us a ring at<br>
360-403-7207. OR, at any time day or night, you can start a
support ticket that<br>
immediately gets sent to all of the support people by going to...<br>
<br>
<a href="http://www.midnitesolar.com/help">http://www.midnitesolar.com/help</a><br>
<br>
The ticket method is kinda cool because it gets people thinking
about the problem<br>
as soon as they see it.<br>

<div dir="ltr">Hive mind-
<div>hoping you all can help me solve this mystery issue.</div>
<div><br>
</div>
<div>System:</div>
<div>Magnum double panel with Parallel stacked 2x4448 pae
inverters.</div>
<div>Classic 150 charge controller wired with an NMEPV 50 (din
rail) and NMEPV100 </div>

</div>
<div>Issue:</div>
<div>every morning the 100 amp din rail breaker is tripping.
from what I can gather simultaneously the magnum RTR shows
the AGS go into error. Re set the breaker and the solar works
fine for the rest of the day. </div>
<div><br>
</div>
<div>Not 100% sure the AGS has worked (under normal operation)
at all other than at commissioning and recent testing. </div>
<div><br>
</div>
<div>Of course on site i cant get it to fail.</div>
<div><br>
</div>
<div>Tested the AGS by setting start voltage to 48.2 vdc and put
the system under load....... voltage drops and generator
turned on with no pv-> Batt breaker issue. </div>
<div><br>
</div>
<div>last visit, chasing one theory, I re routed the battery +
from the mnpv100 directly to the battery + terminal as
opposed to the battery + bus bar in the inverter panel still
didn't solve the problem.<br>
</div>
<div><br>
</div>
<div>I cant figure out if it the classic causing the issue or if
it is the inverters and the AGS.</div>
<div><br>
</div>
<div>Any input would be appreciated.</div>
<div>Thanks</div>
