<DIV></DIV>Hi Mark,
<DIV><BR></DIV>
<DIV>In stacked systems I've usually seen the inverters not charging the same
amount. </DIV>
<DIV>Seems like they should share the charge as well as load, but doesn't seem
to be the case.</DIV>
<DIV><BR></DIV>
<DIV>Was the unloaded one above the other?</DIV>

size=2 face=Arial>This came up because I was looking at the summary on the
Mate during charging and it showed that one of the stacked slaves had 0.0kw
charge power. Strangely enough, the ac charge current showed 16 AAC. This is
how I got on the subject with tech support. They said that the 0.0 kw
charge power was perfectly normal because the charge controller was
trying to reduce the charge current by drop operation of one of the stacked
inverters.</FONT></SPAN></DIV>
