<p>That's the whole point: we need the LBCO to be higher than 48v to
catch the beginning of that steep drop off, so that there is still
enough reserve left to keep the monitoring and solar charge
controllers in operation, and avoid the dreaded dark start. With
Simpliphi, we don't have the dark start, but it still requires
manual reset. This isn't theoretical, we have been having
serious trouble with a system because of Schneider's inability to
set the LVD above 48 v. Also setting the voltage higher (lower
DOD) extends the cycle life of these batteries. Otherwise, I love
the stable 51 volts of Li+, even under load. <br>

<p>Hi Ray,</p>
<p>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.</p>
<p>XW+ is default 44V and adjustable 36 to 44 vdc.</p>
<p>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.</p>
<p>I am not plugging Schneider and have done work for
both Outback and Schneider as well as my clients.
Hope this helps. </p>

<p>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). </p>
<p>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. </p>
