What could be simpler?
For some reason I can't help think of the Great Leap Forward in Chine
where Mao had all the peasants gathering up all the iron objects and
melting them down in small furnaces to help increase steel production.
Of course none of the "steel" was any good.
I guess it is because here I see a bunch of great industrial control
equipment stuffed into a tiny box and dropped in someones basement.
That's alot of stuff waiting to break or hang up or reset or something.
I really have to wonder what the operating state of this piece of
equipment will be in 3 years and if still operational, how many
person-hours of support and maintenance will have been expended.

Here's the internals of the one we installed.

It's a Radian, the batteries are Sony, there's a PLC in the door
controlling everything, and a Vera Z-Wave controller for the
programmable outlets.
The BMS is on the door, connected by the long cable you see at the
bottom. It's not really long enough, which I complained about.
The transfer switch is a Generac component, very reliable unit, rated
at 200A.
There is a DIN rail next to the inverter that holds all the internal
wiring, metering, external connections.
One thing I would advocate, never try to make any connections with
this unit powered up. It is very tight in there and the risk of
touching a live terminal is high.
There is a 200A main breaker and a battery breaker, which is software
controlled for powering down from the front panel. Startup requires
holding in a DC breaker for the electronics for a few seconds then
engaging the main battery breaker. The instructions says five seconds
but I find it takes about 15.

Enclosed is a photo of what appears to be a test/lab Sonnen system
published in the 01/30/2016 edition of "Power Magazine.
Can plainly see the 8kW Outback Radian inverter and I assume four
12V Sonnen (Sony?) 8kWh Lithium-Ion batteries. Assume this is a
"standard" 48V Radian inverter.

Yes, correct on both. The generator support is there, I did not
use it.

Chris,
Nice finish on the Sonnen install. It looks fabulous. My
understanding is the Eco 2-8 integrate the 4kW radian, and
the 10-16 incorporates the 8kW radian. I assume generator
support is fully supported

I promised a picture of the Sonnen installation. As these
units are getting close to being appliances in the same
vein as home audio, we wanted to have a clean finish so
we made some mill work to complete the top of the unit to
the ceiling and hide the ugly conduits.
