This seems like a lame suggestion, since the generator has no idea of when the batteries will be satisfied--it only responds to the on/off signal from the Sol-Ark. I would think that the unit could be programmed to ignore the frequency drop when it sends the shut off signal to the generator. <span>The system has an an Ecogen 15kW.</span><br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"> Not having an exercise function is also a miss.

Gen start can be programmed with voltage or SOC, however gen stop is not a function that can not be readily programmed. Instead, the Sol-Ark is programmed to charge the battery bank to 90% of the rated Ah capacity of the battery bank before turning off the generator. You can ultimately adjust this gen stop parameter to be based on a specific SOC or voltage, but I believe that doing so requires a call into tech support. The tech I spoke with updated a setting (having to do with a TOU parameter I believe) that was not accessible via the system interface. AGS from Schnieder, Outback and even Magnum are less clunky, but I am hoping that Sol-Ark will eventually come out with new programming to remediate these minor but nevertheless, important issues</div></div><div><br clear="none"></div><div>-Chris</div></div><br clear="none"><div class="ydp84fbc9deyiv4104453845gmail_quote"><div class="ydp84fbc9deyiv4104453845yqt6477094269" id="ydp84fbc9deyiv4104453845yqt88243"><div class="ydp84fbc9deyiv4104453845gmail_attr" dir="ltr">On Wed, Nov 11, 2020 at 3:58 PM Jay <<a shape="rect" href="mailto:jay.peltz@gmail.com" rel="nofollow" target="_blank">jay.peltz@gmail.com</a>> wrote:<br clear="none"></div><blockquote class="ydp84fbc9deyiv4104453845gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex;"><div><div dir="ltr">Hi Chris</div><div dir="ltr"><br clear="none"></div><div dir="ltr">I would install a timer.
