My system always drops the slave inverter, mounted at the bottom, when
the charge backs off. It is a FW 500 setup. <br><br>

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

<font size=2 color="#0000FF">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.<br>

<font size=2 color="#0000FF">I always figured that the slaved stack would
rise and fall in unison to meet the current demand.<br>
</font> <br>
<font size=2 color="#0000FF">I do have them running at variuos
"power save" levels so I suppose it is possible that entire
chargers are being dropped, but I thought that was only for managing the
on/search mode on larger stacks.<br>

<font size=2 color="#0000FF">I am guessing that this is more a matter of
reporting errors in the mate.<br>
