Does anyone make a 1000vdc single phase inverter?

Thx Brian.
I guess I was thinking that 50kw + was probably
A darn big house and probably be outbuildings
that the inverters would be installed on.
Yea bringing 1000vdc to a house is a bit much but then
we said that with 600v too.

Currently up in the air as to whether 2020 will allow that on 1- and 2- family
houses. If so then yes...currently don’t know of any.

Thanks for all the input guys. After looking at the 3 phase with
transformer options with some transformer manufacturers, that has been
pretty much ruled out due to complexity/cost.
With single phase step-up and step-down transformers, even at 600VAC, it
still requires some monster wire.

Good advice already on this thread. A couple of points to consider:
1. Re: step-up/step-down option (probably what I'd do): definitely pay
attention to transformer spec to minimize both magnetization and operating
losses. Newer DOE 2016-compliant transformers are MUCH better than before,

You might want to look at relocating the inverter(s) closer to the meter
instead of the array, one reason is even if there is some line loss at full
power its less as the voltage goes up and the inverter does not see the
line resistance that can cause high voltage issues at the inverter.

The single phase - 3phase change is too difficult and expensive. Stay with
single phase. I have done this successfully with a step up and down

Transformers seem to have a price advantage using standard voltages. For

Another option would be to locate the inverters near the grid and run the DC at
as high a voltage as possible. Have a separate run of wire
.

Wrenches,
We have a PV array situated about 900' from the POI (240V 1PH). We
initially spec'd (5) 11.4kW inverters and the combined output would be
238A. The wire size required for this current over that distance is cost
prohibitive.
A solution was to use a single 50kW 3 phase inverter at the
