<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">I am talking with a customer who wants to do a standalone system using an Endurance wind machine, solar, and genset. I have no experience with Endurance other than to know it is a good machine. Talking with Magnum today they informed me that the MS 4XXX PAE inverter, combined with the ARC remote control, and BMK battery monitoring kit can do enhanced SOC control. Has anyone compared this with the Outback as I have not used the PAE inverter yet, only the AE inverter? <br>Darryl<br><br>--- On <b>Wed, 7/21/10, Darryl Thayer <i><daryl_solar@yahoo.com></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><br>From: Darryl Thayer <daryl_solar@yahoo.com><br>Subject: Re: [RE-wrenches] RETURN AMP SETTING<br>To: "RE-wrenches"

Following Ron's advise start at C/5 for SOC less than 50% then C/10 till about 70% SOC and then C/15 till 80% then C/20 to 90 %. the problem we have no way to set these values, Perhaps Ron could give is a routine? The closet to SOC charging is the Outback and then the Magnum but both miss the goal. <br><br>--- On <b>Wed, 7/21/10, Dana <i><dana@solarwork.com></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><br>From: Dana

<p class="yiv1737787596yiv1478977914MsoNormal" style="margin-left: 0.5in;"><span style="font-size: 10pt; color: blue;">Can I infer that if you are
shutting off the gen before charge rates drop in absorption that you are
running only briefly in the absorb phase? Or do your charge currents remain
high through out an extended absortion phase?</span></p>

<p class="yiv1737787596yiv1478977914MsoNormal" style="margin-left: 0.5in;"><span style="font-size: 10pt; color: blue;">Perhaps you have plenty of PV
which you rely upon to bring the batteries up through the absorption phase,
once the gen is shut off.</span></p>

<p class="yiv1737787596yiv1478977914MsoNormal" style="margin-right: 0in; margin-bottom: 12pt; margin-left: 0.5in;">The Onan RS20000 shown in the generators article in HP
131 page 98 has performed flawlessly as backup support to an Outback quad-stack
of VFX3648s. Differences, however, are that this 20kW gennie charges four
inverters, rather than two; the elevation is 6,600 feet for about a 20% output
deration; there are no huge loads above charging draw; and the client is aware
enough to shut it off before absorption reduces the charge rate - all different
conditions than you have described, as the gennie is usually fully loaded and
running in balance.<br>
<br>
Darryl is right about the amount of words necessary.</p>
