Jeff O. and Jeff C.,

OutBack can only do three inverters in a three-phase application. One
inverter (3.6kW max) per phase. They haven't worked out the communications
for stacking multiple inverters on each phase yet.

Take a look at the Exelteck MX series. They can do up to 60kW at 208V
three-phase with up to a 120VDC battery bank. Excelent inverters, although
not super efficient. Figure on 10W idle loss per 1kW MX Power Module and 85%
conversion efficiency. Exeltech could also probably make them with a higher
voltage input

You should also look into the SMA Sunny Island system, especially if these
apps are overseas. The US version is not ready for three-phase (yet), but
the European model is.

Cheers,

I'm having a heck of a time (again!) trying to find a 30-40 kW o-t-g battery
based inverter. I need 3 phase perferably 240 or 208 VAC as I don't want to
feed transformer cores. I think wire is cheaper and more reliable than
transformers and more PV to cover tare loses. Even though my
transmission/distribution issues are not slight, I'm still leaning in this
direction.

I would love a battery over 200 VDC but will take anything. I've used the
options from Australia and care not to repeat the experience. I have 2
applications both outside the U.S. so U.L. is not going to limit my choices.
Genset interface and a battery charger will make life easier too (since I'm
askin')!

Any ideas??

Thanks,
