Hey Allan,
SMA is about to release a 6 KW version of the 5 KW SI if that figures in
your considerations at all. And of course the advantage of the SI is
you can feed power into the micro-grid anywhere along the backbone
without AC coupling relays in true off-grid mode. But to stack 6 you'd
need a Multi-cluster box I do believe. It does get expensive.
Have a good weekend!

Wrenches,
We have been asked for a design for an off-grid system to reduce
generator runtime for a mountain resort. Initial projections
(consumption measurement results not yet available) suggest 15-20 kW
of PV and around 30 kW of inverter capacity. However, the generators
and existing wiring are three-phase 120/208.
My assumption is that our only options are a set of six Sunny Islands,
or 9-12 Outback GVFX3648s. Are there any other options or approaches
that I'm missing?
Thank you, Allan
