Sorry, I did not read enough of this string, I wrongly assumed the issue was
the 4/0 wire not being large enough for the addition. Perhaps be ever more
conservative on the PV expansion and use a Apollo HV100? The migration to 48V
is certainly a logical solution but can be a horrible economic solution if they
have an expensive battery bank that is too new to replace and too old to add to
which is quite likely the case, it gets even worse if there are 24V loads like
refers and freezers. Those SW's seem to live a mighty long time, one of the
best "do-all" inverters even made.
