Would a 96 cell Panasonic module fit in the space you have
available? It would give you sufficient voltage to charge this
battery.<br>

<div style="font-family:arial,helvetica,sans-serif">It's going to
be a Victron inverter. I'm not sure if they make a DC-DC
solution for this charging scenario or if there is another
way to accomplish it without too much cost and complexity. I
was half-heartedly thinking about an AC coupled
microinverter, but that has drawbacks in terms of efficiency
I think. Maybe that's not any worse than DC-DC conversion -
I'm not sure. AC Coupling would probably be cheaper and
easier. Monitoring might be difficult/limited. And AC
coupling would require that the inverter be on (inverting)
which isn't ideal for this situation either.</div>
