The possibility of dark start and 30% higher cost are 2 reasons we have
preferred Simpliphi lately. Simpliphi just requires resetting its
breaker on top of the battery. Also the Simpliphi allows more layouts,
so it doesn't stick out into the room. We have one customer that has a
system with each, and so far they prefer the Simpliphi over the Blue
Ion. Both are high quality solutions, but being able to afford more kWh
of storage solves many issues.

Specifically with Blue Ion, the installation manual recommends 48V as
LBCO, but also recommends setting it a bit higher:
"Recommended Low Voltage Disconnect Setting: 48 VDC (~2-10% State of
Charge)
BMU will power down the Blue Ion 2.0 cabinet at 44 VDC (<1% State of
Charge)
Based on system discharge patterns, SoC and voltage correlations will
vary.
We recommend you err on the side of caution with a higher LVD setting
and adjust as necessary.
To prevent a dark start event, we recommend leaving a little reserve
“fuel in the tank”."
I have used 48VDC with success, and had one system indeed shut down at
44V, leaving 1% left to reboot.

I see what you mean Ray. Sorry I misread your mail. There are not
too many batteries out there that need LBCO above 48V. Which ones
are you talking about please?

Hi Ray,
Which XW? There are 3 now. The old graybox XW defaults at 44V LBCO
and the range is 40 to 48V. There also was firmware back in its day
that got older units updated. Schneider still has the firmware
under discontinued products.
XW+ is default 44V and adjustable 36 to 44 vdc.
XW pro is running downstairs and I will take a look. It would be my
guess that it is the same as XW+. I think one needs to be sure they
are in Advanced settings to tweak LBCO also.
I am not plugging Schneider and have done work for both Outback and
Schneider as well as my clients. Hope this helps.

We've been having good luck with SImpliphi, the pricing has
recently gotten much more competitive. As it's names states,
its simple. Each 3.8 kWh unit has an 80 amp breaker built into
the top, weigh about 75 lbs, and are a bit smaller than an L16
but with carry handles. We use an insulated 2 pole combiner
block to run all the parallel conductors to the main 2/0
cable. No monitoring, but they do have an handy setup guide
with recommended settings, specific for each manufacturer
(including Outback).
Note to all: Schneider XW can still not set its LVD above 48,
which basically makes it incompatible with most Li+ batteries.
Their tech support has been abysmal as well. We're looking
forward to them as one of the larger companies in the business,
to put additional resources into their engineering, and come
out with at least a firmware update to correct this problem.

Hello Wrenches,
I am working with some people that want to use a 20 kw-hour
to 30 kw-hour 48 volt lithium-ion battery with an Outback
Radian and Outback FM charge controllers.
They are considering using Discover, Blue-Ion, Battle Born
or SimpliPhi batteries.
Does any one have any recommendations of which battery
functions best with the Outback system.
Thanks,
David Katz
