style='font-size:12.0pt;color:black'>I haven’t been following this thread
carefully, too busy, but my advise is, don’t focus on current capability
alone. From Xantrex, find out the “voltage compliance” as well. By
that I mean, “What is the voltage at 52 amps output? Does it vary over
time from 1 msec to 5 sec?” Any motor will need both a voltage and
current to operate properly, and they tend to draw more and more current as the
source (inverter) voltage drops. </span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The XW6048 is rated at 52 amps RMS line to
line between 5 seconds down to 1 millisecond, so if your client’s AC has
a starting inrush surge of 104 amps at 240v, then yep, I think your biggest
problem is not enough inverter. Sounds like just one additional inverter
will be marginal; depending upon the additional background loads you may want
to consider expanding to three total. I think Mick Abraham is right on
here, in his earlier post.</span></font></p>

think I'm going to find that the biggest problem is that there is not enough inverter
capacity capacity with just one unit (the scematic shows a 60 amp breaker on
the output). The system is new ( installed within the last 4 months and
the batteries were new) The AC unit is 240 volt.....</span></font></p>
