Correct, although the consumption meter is also included. They supply the
external metering which you have to install externally in the PV supply
cabling.

The PV design depends on the consumption model, how much battery, but they
do advocate no more than 8KW, which is what we are using on the
installation. I think you could use about 4kW quite easily for a ECO16. It
depends on the daily consumption of the home.

Frequency shift. It will change the micro-grid frequency to 60.9hz

 G should be "Home". Not sure what they were doing there, I will let them

Re: [RE-wrenches] Sonnen Battery & Outback Radian Inverter

[frenergy]

Mark,

We humans many times make quite a stumble when we take a 
big new step (grid tied solar plus L-ion storage with the brains to 
manage all of it).  I agree with you on one hand, we'll probably 
screw-up the first few iterations.  On the other hand I feel pretty 
confident that my sensor laden, computer driven, signal processing, 
technology burdened truck will get me from point A to point B with few 
worries and for many miles.  I think we'll figure this out as there is a 
very powerful incentive to do so.

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.

The BMS is on the door, connected by the long cable you see at the

There is a DIN rail next to the inverter that holds all the internal

There is a 200A main breaker and a battery breaker, which is software

holding in a DC breaker for the electronics for a few seconds then 
engaging the main battery breaker. The instructions says five seconds

Chris: Thanks! More questions.
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?

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? 

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?

Page 15: Is the nomenclature in Figure 2 for the Utility Power
  Meter "G" and the Consumption Meter "D"  reversed?

It came assembled. The only hard part was the external

You have to install the batteries and auxiliary cabinet

How much does the finished product weigh?
  

About 500lbs before the batteries, we used our crane to

There's nothing to stop anyone buying the same Sony battery system and a
Radian 8048A based system and integrating them. I see some dealers in the
UK selling them so they have to be available..

Re: [RE-wrenches] Sonnen Battery & Outback Radian Inverter

[Carl Adams]

Drake,

Pricing is for the package, for Eco 2-8  you get the Radian 4kW plus the
kWh batteries specified.  For the Eco 20 - 16 you get the Radian 8kE plus
the kWh batteries specified.  Here is a price sheet.  Installer cost would
be MSRP - 15% plus shipping.
Reading the link, I'm not sure what the following sentence refers to, the
price of the system or the batteries.



*"The batteries are priced at $10,000 for the 4 kWh model up to $24,000 for
the 16 kWh model." *Literally it says that the cost is $10K for 4 KWh
batteries. When compared to the $24K system cost for a system 4 times as
big, it would seem that they are referring to whole system costs with the
same equipment but more batteries.

They wouldn't sell 4 times as many batteries for 2.4 times the cost (would
they)?

If it is 4 kWh of batteries alone for $10K, that wouldn't be much of a
deal, even if they did last 10 years. We are doing *far* better than that
with AGM, which should last 7 years. If it is for the entire system, it
might start looking competitive.

Re: [RE-wrenches] Sonnen Battery & Outback Radian Inverter

[Roland - RES]

FYI that's a showroom unit with none of their internal wiring, and dummy 
inverter and batteries to keep it light. An actual unit has a tremendous amount 
of factory wiring between contractors, 200a auto transfer switch CT's and 
sensors along with a powder coated steel door in place of plexiglass. The 
Batteries are manufactured by Sony, they come in 48V 2kWh blocks that get 
paralleled together.

Re: [RE-wrenches] Sonnen Battery & Outback Radian Inverter

[Gary Willett]

  
  
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.

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
