<div dir="ltr">I just encountered the same thing. I upgraded a clients Discover AES to a Helios AES and after a few months what you are describing started to occur. I came to the same conclusion and all I could offer my client was "looks like no more AGS for you until we can upgrade to a Victron system.</div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Sun, Dec 14, 2025 at 3:24 PM Chris Schaefer via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>G'day All,</div><div><br></div><div>Came across something I haven't seen in the past and I have over 4 dozen PAE units out there. It has to do with the Max Run Time setting on the ARTR or RTR and the Magnum AGS unit. I normally set the Max Run Time (MRT) to 12 hours. It has been my understanding that this MRT value comes into play when it sees the generator input. Then once the genny runs for say 4-6 hours the AGS then tells the genny to stop. I've been under the assumption that once the genny stops, the MRT would reset back to zero to ready itself for the next time the genny runs. What is happening is that the MRT seems to be accumulating for each genny run and then of course once it hits the MRT value you get the "Fault Max Rn". I can't find anywhere in the literature about the MRT value resetting after the genny stops, but I'm confident that this is the case. Can anyone confirm my thought process on this one or has anyone seen anything like this before? Heading out tomorrow with a new ARTR.</div><div><br></div><div>Your Friendly Neighborhood Solar Guy,</div><div>Christopher-</div><div dir="ltr" class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><p style="text-align:center"><span style="font-size:10pt;color:rgb(31,73,125)"><font face="Arial, sans-serif">Chris Schaefer’s<br></font></span><img src="https://ci3.googleusercontent.com/mail-sig/AIorK4xwQObc1lE4m-NGBGV2ONhmIo5vEAZs2lO5NoIACbJsI4fJ_a1hsiFC2biIJSxI90VJ_atMDSuJtjW-"><br><i><span style="font-family:Arial,sans-serif;color:rgb(31,73,125)"><span style="font-size:9pt">Tel 585-229-2083 or Cell 585-748-1870 </span><span style="font-size:12px"><br></span></span></i><i style="font-size:12.8px"><span style="font-size:10pt"><font color="#1f497d"><font face="Arial, sans-serif">5115
