12.0pt;margin-left:.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>

Darryl is right about the amount of words necessary.<o:p></o:p></p>
