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>
