Simpliphi is another Li+ that is very much worth looking at too. It
comes in nominal voltages that are usable (unlike Tesla) such as 12 v,
24v, and 48 v. It is also rated to 10,000 cycles to 80% DOD, which
actually could outlast the rest of the system. It is Lithium Iron
phosphate which is heavier than the Tesla, but not prone to thermal
runaway. I haven't tried them yet, so I'm just in study mode. The
voltage stability as the battery discharges is very attractive. Even at
high discharge rates, it holds above nominal voltage to 90% DOD.
My problem is I have not been able to figure out how much we can under
size these relative to their lead acid counterparts. Being that they
have better capacity at high discharge rates, are less temperature
sensitive, can't freeze, and can be discharged 100%, I'm guessing we can
downsize them by about half, but I think it would really depend on the
application.
Anyone that is using Li+ (like Larry Crutcher) want to chime in on
sizing of Li+ battery banks compared to lead acid? Downsizing is the
only way we could possibly start making these affordable.

Don't ignore Sonnen, their ECO16 is a solid Lithium based solution. We
installed one in Anguilla and, once we got through some software
issues, the system performed solidly.

HI All,
I hesitate to bring this up, but I’ve had some questions come my
way about the “new” Tesla 2.0
battery backup units. And with the demise of Aquion, looks like
Lithium and LA are pretty much the only games in town.
I have been able to find quite little on line ( surprise), pretty
much nothing from Tesla directly, but some from other folks by
google search.
Does anyone on the list here know anything solid?
For example.
what inverter is being used?
how do they stack?
battery chemistry?
actual size ( depending on which info it changes)
are they actually shipping?
Thanks
