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.<br><br>Have a good weekend!<br><br>jc<br><br><br></span><br>Allan

Wrenches,<br>
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.<br>
<br>
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?<br>
<br>
Thank you, Allan<br>
