It will be interesting to see how this pans out. And at what cost.

IMO adding an auto-transformer to help balance the system output is just another failure point.

It is only required for backup capability.

I think there's a future in HV DC inverter systems, especially as load power distribution moves to DC. Wire gauges go way down and protection devices become easier to source.

The above inverter doesn't solve the problem of the MPPT though. I don't know of any MPPT's that work HV to HV (i.e. a 500 volt input, 400 volt output.)

Your raise a very important point. What you leave out is that the same DC to DC inverter hardware can be controlled equally well by an MPPT algorithm or by a constant voltage input algorithm. Typical grid tie inverters only include the former, but when designed for use with the PowerWall or other battery storage, it is not particularly expensive to add the second control circuit option. That is apparently what SolarEdge has done with their storage compatible systems.
