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.

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.
