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

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

Thanks Jay,
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.
I always figured that the slaved stack would rise and fall in
unison to meet the current demand.
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.
I am guessing that this is more a matter of reporting errors in the mate.
