You don't want to drive for hours and hours to do something that
might not fix the problem.<br>
<br>
Without knowing exactly what is happening, I would bring a spare
Classic and also a new breaker<br>
which I think I heard we were sending you....<br>
<br>
If the Classic is plugged into the internet, there is the
possibility of monitoring it to see what is<br>
going on just before the breaker trips. I would just bring
another one in this case if you have one...<br>
Otherwise, call our support and see if there is something they can
do to help in this regard.<br>
<br>
Strange things do happen in this industry ! Troubleshooting isn't
so bad as long as you don't have<br>
drive or take a helicopter a long ways just to find that the unit
is turned off.<br>

I agree that you should try replacing the 100A breaker, I

<p class="MsoNormal">An update on this issue:</p>
<div>
<p class="MsoNormal">On my initial visit to diagnose this
problem I changed the AGS settings higher volt start and %
state of charge start. The report from the client is that
this has fixed the AGS issue. So now I am just dealing
with the 100 amp breaker tripping. </p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">The trip time from the client is when
the sun hits the panels and once reset for the day it will
not trip until the next morning. What could cause this? </p>

<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">You are all right that the first step
it changing out that breaker that will be the first on the
list when I am back on site. I hope that is the only
issue because as usual this system is 2 Hrs from the shop
with no cell or internet coverage.</p>

<p>Hi Daniel,</p>
<p>Do you know what the error is on the AGS? What are the
start set points that you have? Jay could be on to
something if the battery voltage is collapsing before the
generator can start, the cc current could be high. Do you
know specifically what time of day the breaker is
tripping?</p>
<p>I'd check the Midnite logs and consider starting the
generator sooner. Is there large voltage swings (this
could indicate bad battery or large load)? Make sure the
wire is cleaned and torqued properly onto that breaker. </p>
<p>How big is the battery bank and what is the tilt and
azimuth of the panels?</p>

<p class="MsoNormal">What it sure sounds like like
is a big load on the batteries, it hits faster
than the AGS can start, and the caps in the
classic are dumping into the super low battery
voltage. If this is happening in the AM,
guessing with enough light to get the CC alive </p>

can measure the lowest voltage which should give

bad battery or too big a load or both. </p>
