Vince, sorry in advance to sort of Hijack your thread.
Brent, it is your wife who works in the UPS sector isn't it? Could she comment on if there is a smallish double conversion unit which also has a 12VDC output direct from the battery storage? That would be the best of both worlds in my application, 240VAC uninterruptible for the AC equipment, 12VDC for the mount and heaters and battery charge state managed all in one unit.
There are two of us commonly observing and imaging respectively at the one site and if we could cover off enough load to pad both the DC and AC components of both scopes through a power failure in one box it would be worth shelling out some money on. We commonly enough have short failures, long ones would be a bit of overkill.
