<p>Chris: Thanks! More questions.</p>
<p>Page 14: I am assuming that the Sonnen system is comprised of the
components and functionality encompassed in the box in the upper
right side of figure 2. And the Outback Radian is the inverter
used for "F" - the "Storage System" inverter?<br>
</p>
<p>Pages 14, 15, and 29: No info on PV array sizing is provided.
Does the Sonnen design assume that a totally separate grid-tied
inverter system already exists or must be installed if PV charging
is desired? <br>
</p>
<p>Page 15: The system is AC coupled. When in "Backup Mode" how does
the Sonnen BMS control charging from the external grid-tied PV
inverter system once its battery modules are fully charged and the
house loads are low? Does the Sonnen BMS handle this situation
without disconnecting relays or frequency-shift throttling?<br>
</p>
<p>Page 15: Is the nomenclature in Figure 2 for the Utility Power
Meter "G" and the Consumption Meter "D" reversed?</p>
<p>Regards, Gary<br>
</p>

<div>It came assembled. The only hard part was the external

not very proud of it. </div>

<div>About 500lbs before the batteries, we used our crane to
lower it down the stairwell. Two people, a handcart,

<div>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.</div>
<div>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.</div>
<div>The transfer switch is a Generac component,
very reliable unit, rated at 200A.</div>
<div>There is a DIN rail next to the inverter
that holds all the internal wiring, metering,
external connections.</div>
<div>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.</div>
<div>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.</div>

<div>Nice finish on the Sonnen

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</div>

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.
