Maybe it's not an overload, perhaps a low voltage cutout caused by some
issue with the either new 2/0 battery cables or their connections.<br>
The Staber WEB site indicates only a 11 amp surge which shouldn't
overload trip a FX2524T.<br>

<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">Here’s one that has me
quite stumped, and perhaps one
of you esteemed Wrenches has an answer or suggestion.<o:p></o:p></span></font></p>

<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">In 2000 we installed a
clean, basic budget off-grid system in
a new remote manufactured home for a client, a single woman who lives
quite
consciously and frugally. The system was 24V, 600W of PV, Trace DC175,
DR2424
inverter, Solar Boost 50, eight golf cart batteries and a Tri-Metric,
along
with a Sun Frost RF16 and Staber washer. The system had worked
perfectly for
her, and we replaced her batteries with same last year. <o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">She called a couple of
weeks ago because her life situation
had changed and she now worked from her remote home using cell phone
and
satellite internet. The new satellite equipment had been troublesome
and had
already been replaced, but would still shut down intermittently. Given
that she
had already replaced the electronic equipment with same, I suggested
that she
finally was facing the problem of modified-square wave DR waveform. I
said that
while there were no guarantees, a switch to a sine wave inverter would
likely
cure the problem.<o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">On Friday I removed the
DR and installed an Outback FX2524T.
No other changes, other than longer 2/0 cables. I changed a few
settings for flooded
batteries and her generator using a service-truck Mate, but did not
sell one with
the system. Everything booted up properly, job done, let me know how it
works
out.<o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">Friday evening she called
with no power. The red “error”
LED was lit. I had her reboot the inverter with the DC breaker, and all
was
restored. The only thing she had run was the Staber washer. I assured
her that
the inverter could handle a DC reboot without trouble. The next day
(yesterday)
she left a message that she had six times overloaded while completing
the wash
load with the Staber. Everything else was fine.<o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">On Monday she will call
for an explanation of what is
happening and advice on how to correct it, and I won’t have any. What
would allow a Staber to run fine on mod-square DR power, but overload
an FX of
the same capacity? The Staber was likely ordered with notification of
the need
for a mod-square control board, as they instructed in the early days,
but I
wouldn’t expect it to be incompatible with sine-wave AC. <o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">Not having expected this
problem, I didn’t go hunting
for problems such as a ground fault in the washer circuit. I haven’t
done
any troubleshooting, of course, but would like to have some idea what
to look
for. The only anomaly that I noticed was that some of her Tri-Metric
program settings
had changed from what I checked when I replaced the batteries: CEF of
L98
instead of H97 meant she always showed 100%, and a couple of other
settings
weren’t what they should have been. I noted this and reset it, but
considered it an unexplained glitch, as though a nearby lightning surge
had
scrambled some settings without damaging anything, or she had
inadvertently
pressed the wrong button sequence and changed settings. Now I’m
wondering
about extraneous things: a bad ground? Mice chewing through the laundry
circuit
(although she has cats…)?<o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">What would cause an
overload to be detected by the FX that
wouldn’t have tripped the DR all these years?<o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">All ideas and solutions
would be appreciated. I will likely
have to make a return trip, not under warranty, though.<o:p></o:p></span></font></p>
