Hello Howie,
You should be aware that Discover Li-ion battery does not have adequate
protection to prevent damage if charged below freezing. The data sheet (see
attachment) shows that you can charge the battery down to -4°F and adds a text
warning not to charge below 32°F.

Dave,
No problem. I don't know much about Sonnen, but what I do know is that not all
GT inverters do the same impedance test. Outback Power did a bunch of testing
and they found one inverter larger than 6 kW that would be able to tell that it
could impact the voltage coming from the Radian,
I love IronE's temp tolerances.
and as far as LiPO4 goes AES is certainly neck and neck with the VERY best of
LFP. Their BMS is very robust and well designed (And they're made in Canada)

Just my 2 cents, look at Blue ion from Blue Planet Energy, l have installed
new and also switched over from other batteries, been very happy with
performance

Howie,
I’ve used a few different brands and am currently using the Discover AES, I
have a quad stack of the coupled to an dual stack of XW inverters and they are
working great,
As for another post comment that these companies are looking to be bought out,
Discover is long time battery
Chris,
Thanks for the reminder. I've stayed out of the Lithium option until now,
largely because of just that, but now that I'm delving in, that is a good
reminder. I swore off bleeding edge products years ago, but I guess I'm
running the risk of bleeding again...

Thanks Dave. Do you need an add-on to get the interface from the AES to the
Conext gateway?
Have you used Iron Edison's lithium offering? Is there a comprehensible
reason for the significant price differential between the 2? Do you know
where the IronEdison are manufactured?

Kienan,
Thanks for the info here. That is really interesting about the 6kw
limitation. Outback clearly states that limit, but Sonnen has managed to
surpass that with their programming of the Radian.
The PV part of the system is already existing, so this will need to be AC
coupled entirely. I may
I'd be very cautious about getting too cosy with any of these battery
companies, it seems their only aim is to get bought. Sonnen was acquired by
Shell Oil, Pika by Generac. I'm a generac dealer so I am exploring what
their intentions are. I doubt Shell will be gung-ho to continue to support
Hi Howie,
Have you looked at Fortress Power batteries? We're about to install
some and they look like a very decent battery. Google will get you the
basic info to start.

Hi Folks,
About to spec my first Lithium battery backup job. The client is not a
heavy user, but wants things done right more than being totally cost
effective.
We put in 14kW of net metered solar using SolarEdge and now he wants the
backup component. This was significantly oversized for his use,
Thanks Darryl,
Yea, it used to be two separate 200A services. At some point, someone
decided to turn one of those panels into a sub and run it all of a single
service.
Regarding paralleling Radians, I know that the max solar input when AC
coupled is only 6kw for an 8kw inverter. When they are
the 2 each 200 Amp panels is to overcome the 42 circuit limit in one
panel. must be a big house. This sounds like a whole house backup. you
will need a transfer switch much like a whole house generator switch unless
your customer needs TOU or some other grid service.
For the AC coupled
Hi All,
Does anyone have a good recommendation for an AC coupled energy storage
solution for someone who has a 27.6kw array with two SE11400A-US inverters?
The output of one of those inverters is more than a Sonnen or Radian can
handle (which is what I am most familiar with).
I am not sure yet
