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>

suppose it is possible that entire chargers are being dropped, but I thought
that was only for managing the on/search mode on larger
