[RE-wrenches] 30 kW Inverters

[Jeff Clearwater, Village Power Design]

Hi Peter,

I don't have history with the PV Powered's but 
they have a 30 KW I've heard good things about.

A couple of Solectria 15 KWs would make a nice 
balance between "single inverter" and redundancy 
and ease of install.

2 or 3 Fronius IGPlus 12 KWs would also be a good 
solution.  Power One (Aurora) also has a 12.5 KW 
with multiple channel inputs and other nice 
features.  Wall mount advantage here too.

And if wall mount is important you don't need the 
Tower - just mount 4 or 5 Sunny Boy 7KWs above a 
gutter.

Lot's of ways to do it.

Hope that helps!

Best,

Jeff C.
