charge rates drop in absorption that you are running only briefly in the absorb

re-wrenches@lists.re-wrenches.org<BR><B>Subject:</B> Re: [RE-wrenches] Propane
Generator, Dual Outback Inverters<BR></FONT><BR></DIV>
<DIV></DIV>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.<BR><BR>
