The AGS settings are stored in the MATE3, so it tries to tell the inverter to trigger the external relay once the 2 minute voltage has been reached, but if LBCO has been reached, the inverter will not supply voltage to the coil.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>This logic does not work. Let’s say you have LBCO set to 46.0V and the 2 minute start voltage set to 47.2V. Under a very heavy load, it is completely plausible that the LBCO could be met before the AGS via the inverter has time to start the generator. The only “solution” is to have an unacceptably high (IMHO) spread between the 2 minute start and the LBCO.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>In this case, I don’t want to set the LBCO too low (i.e. default) because the system is unattended and if the generator does not start for whatever reason, it is reasonable to expect that the battery voltage could slowly decrease to the LBCO and then stay there for a long period of time until the problem is discovered. I want to keep the LBCO relatively high, but I want the generator to reliably start using start timers, SOC, or load. I think this is a poor implementation of this feature, leading me to consider a completely separate or auxiliary AGS system that is voltage dependent without relying on the inverter relay to start the generator.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:#1F497D'>Jason Szumlanski<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Fafco Solar<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p></div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> re-wrenches-bounces@lists.re-wrenches.org [mailto:re-wrenches-bounces@lists.re-wrenches.org] <b>On Behalf Of </b>holtek@sbcglobal.net<br><b>Sent:</b> Friday, September 30, 2011 12:06 PM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> Re: [RE-wrenches] Re-configuring expanded array<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'>Maverick,</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'>I don't think system owner will let me pry his mate3 out of his hands.....and oops! it will be 2- 6 slot combiners....thanks for the feedback.
