The batteries drop rapidly in voltage but hydrometer readings are in the green. Turning off the inverter and just using DC doesn't change anything. Meters on the Mate, Outback MX and Whisper controller are all the same so it's not a metering problem. On the way to bed the batteries were at 25.4, overnight with no loads they dropped to 22.9 then a short 15 min. charge with a generator brings the batteries back up and two hours later they are at 25.8. This scenario has occurred several times and then doesn't appear for a day or two.<o:p></o:p></span></font></p><div><p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:12.0pt'><o:p> </o:p></span></font></p></div><div><p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>It doesn't seem to be sulfation as the batteries are reading good on the hydrometer every time. All cells check out. The inverter doesn't seem to be the problem. They have a Sunfrost on a separate DC circuit. It sounds like an intermittent circuit problem or electronics issue. Customer has checked and tightened all the connections he can get at but hasn't been inside the components. Would appreciate any suggestions or clues before I make the trip.<o:p></o:p></span></font></p></div><div><p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:12.0pt'><o:p> </o:p></span></font></p></div><div><div><div><div><div><div><div><p class=MsoNormal><font size=1 color=black face=Helvetica><span style='font-size:6.0pt;font-family:"Helvetica","sans-serif";color:black'>Ron Young<o:p></o:p></span></font></p></div><div><p class=MsoNormal><font size=1 color=black face=Helvetica><span style='font-size:6.0pt;font-family:"Helvetica","sans-serif";color:black'><o:p> </o:p></span></font></p></div><div><p class=MsoNormal><font size=1 color=black face=Helvetica><span style='font-size:6.0pt;font-family:"Helvetica","sans-serif";color:black'>earthRight Products - <a href="http://Solareagle.com">Solareagle.com</a><o:p></o:p></span></font></p></div><div><p class=MsoNormal><font size=1 color=black face=Helvetica><span style='font-size:6.0pt;font-family:"Helvetica","sans-serif";color:black'>Alternative Energy Solutions ~ Renewable Energy Products<o:p></o:p></span></font></p></div><div><p class=MsoNormal><font size=1 color=black face=Helvetica><span style='font-size:6.0pt;font-family:"Helvetica","sans-serif";color:black'><o:p> </o:p></span></font></p></div></div></div></div></div></div></div><p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:12.0pt'><o:p> </o:p></span></font></p></div></div></body></html>
