big honking off-grid inverters [RE-wrenches]

[Marco Mangelsdorf]

Has anyone out there used the Abacus or Sunverter big inverters for off-grid
applications?  I've been looking at the specs on them and could find no sign
of any UL or ETL listing.  Are these big boys made in China and imported
under the radar screen with no need for listings since they don't appear to
be appropriate for sell-back, grid-connected applications?  Specifically,
I'd be interested in hearing from anyone who has used a 50-75 kW off-grid,
battery-based inverter.  I haven't given up on the idea of using a dozen or
more OutBacks, but am seeing what else is out there in da Real World.

Thanks,
marco
