<div dir="ltr">An update on this issue:<div>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. </div><div><br></div><div>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? </div><div><br></div><div>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.</div><div>Thanks for your input.</div><div>Cheers-</div><div>Daniel</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr">Daniel Tittmann <div>CTO</div><div>Greenwired</div><div><a href="http://www.greenwired.com" target="_blank">www.greenwired.com</a></div><div><a href="mailto:daniel@greenwired.com" target="_blank">daniel@greenwired.com</a></div><div>707-923-2001 (office)</div><div>707-206-5088 (Cell)</div></div></div></div>

<p dir="ltr">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 dir="ltr">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 dir="ltr">How big is the battery bank and what is the tilt and azimuth of the panels?</p><div class="HOEnZb"><div class="h5">
