What are they rated in KWH? 3.3KW for how long? 1 hour? 2 hours? What
I'd like to do is relate it to how long I can run a site at 25, 50, 100
watt load.

There's not a lot of technical information available about them, don't
they have an integrated sinewave DC-to-AC inverter? I could be wrong
but I believe they output AC. Assuming a typical installation for
their target market, residential, do they require purchase of a
separate DC-to-AC inverter?
They're rated at 3.3kW load (AC) to power a house.

Only hassle is that they are 450 volts (or in that neighborhood).
Big challenge finding DC-DC converters for that, or maybe go back
to battery-inverter-DC power supply design.

$3000 is not so bad for something that can deliver up to 5kW

I am interested to see the results of integrating two of these
in parallel with an off grid solar array. At first glance it
appears a great deal less expensive than buying a dozen 12V
200Ah lead acid AGM batteries to make a string. And should
last a lot longer in 60% cycle depth daily cyclic use.
Interesting they've cancelled the 10kWh model ($3500) which
had a much shorter lifespan, the 7kW model is rated at 5000
cycles.
