<p>My favorite right now is Simpliphi: company has been around since
2002, and as the name implies, they are simple to install. There
is no external monitoring or comm, just an output breaker on each
battery that can be reset if the internal BMS ever shuts down for
any reason. We've done several sets in new systems, and as
battery replacements with older Outback equipment. Simpliphi
provides a nice programming cheat sheet for all the brands of
inverters and charge controllers.</p>
<p>For smaller systems, the LiFe Blue batteries are great. They
have the best monitoring (simple blue tooth to a free phone app)
and they are the only Li+ battery that has a solution for cold
weather charging that I'm aware of. Other battery companies have
just given us the shoulder shrug and tell us to install the
battery in a conditioned space. Not a good answer for many off
grid systems in the mountains. <br>
</p>
<p>I'm not a huge fan of Blue Planet; if their battery is over
discharged, it requires a 48 v dark start. I also did not find
their enclosure to be NEC code compliant to connect conduit to.
We had to modify it to allow a 2" KO. Cable routing and
connections internally are also awkward. Its just a computer rack
cabinet repurposed for batteries, but it does have pretty blue
Lights (which we disconnected at the customer's request) Finally
the comm system is based on the E-gage, which was never designed
for off grid and depends on a constant router and internet
connection to monitor. That is another deal killer for some
remote projects. Internet connectivity is great when available,
just the monitoring can't be dependent on that connection. Their
tech support was good though.<br>
</p>
<p>Beware that Schneider inverters LBCO can't be programmed over
48v, which is a deal killer for most Li+ batteries. We currently
have a system that we are adding a relay to shut off AC output,
that will be triggered by the charge controller. That is just an
amazingly kludgy solution for a really dumb problem: not allowing
higher settings of the LBCO. Until Schneider releases a firmware
update, they are not even being considered for future projects. <br>
