Most string inverters that are used on solar these days go to 600 VDC input
with many now doing 1000 VDC inputs.
So that gets the one side going. I wonder if you could use a UPS on the
output side of a grid tie inverter to fake it into putting out current.

If going DC, there are some challenges doing DC-DC conversion from a
battery that is storing at 350-450 volts. There are off-the-shelf
inverters if you're going to AC, but that is beyond the range of DC-DC
converters that I'm familiar with.
Might have to use an inverter for no other reason.

I would want to run it DC, but it ain't bad. We're paying in the
neighborhood of $1500 for about 5KWh with SLA batteries, so this would
be a serious consideration.
Actually it is DC, says "inverter not included".
