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.
We haven't designed/installed a 30 kW-dc class
system for some time now (last time we used a
Xantrex PV 30) and are currently investigating
what is available in terms of single inverters
with 240V 3Ph output. Our customer has enough
roof space to for 58 kWp of modules, but we have
to split the AC output into two separate
services. So the first thing I've noticed is
that there are not many inverters in the 30 kW
range: Satcon PowerGate 30, Xantrex GT30 and by
comparison a Sunny Tower with 6ea 6 kW SB
inverters.
We will be feeding 240 3P so the GT30 and ST will need transformers.
So, I'm inclined to look more carefully into the PowerGate 30, first.
I am looking for some feedback from folks who
have recently installed 30 kW inverters. If this
is contained in an archived thread, please
direct me appropriately.
