[RE-wrenches] Outback VFX upgrade question

[John Blittersdorf]

Alan,
  It appears to me that everyone miss read your question.  If your customer
does not need a generator, then his solar charge controller needs to be
able to be set up for the lithium battery voltage settings.  So the
inverter simply needs to be 48 volts and has nothing to do with charging
battery.  You could use any 48 volt inverter and use the MATE. The inverter
would only provide LBCO to protect the battery.  As far as a used VFX 3648
contact me off list.
