I’m chiming in
a bit late on this one.
Solaredge is
compatible with SunPower. See the P400:
http://www.solaredge.us/groups/us/powerbox/module-add-on
Solarege has
been very popular in the Bay Area among SunPower and
non-SunPower dealers.
I’ve attended a
Tesla Powerwall training and the product is coming but it
will probably be a slow and limited rollout (just my gut
based on what I saw). The 400 volt battery output in
particular will be the most revolutionary part of the
product in my opinion. The Storedge product is their 1st
gen battery product (I believe) so only time will tell how
it works:

I’m not
convinced that any of the other lithium products are ready
for prime time. They are expensive and I don’t personally
want to spend the time or money to experiment with them at
this point. That said, we recently commissioned our first
dual Schneider XW+ system with AGMs and besides a few
hiccups, it looks like a very customizable and clean
package. I agree that storage is the future and certainly
the reduced size and increased cycling ability of lithiums
make them very appealing.

I
have a residential client who wants a grid tied PV system
with battery backup. The client wants everything to be top
of the line: Sunpower modules. Tesla Powerwall batteries.
Unfortunately,
I have been spending time recently researching "smart energy
storage" for commercial applications focusing on peak demand
shaving. These are 480 V 3-phase systems with 30 kW
inverters and 48+ kWh Lithium technology batteries. I think
I am beginning to understand the performance trade-offs and
how these systems can complement PV to reduce demand charges
as well as usage charges.
My
problem, is that I have not spent as much time researching
the newer residential GTBB offerings. I have studied the
Juicebox offering – Schneider XW5548 plus NMC Lithium
batteries -- but that’s about it. I don’t know the default
vendor for the NMC batteries and if not Powerwall, could
Powerwall be a replacement?
Otherwise,
does anyone know how to access the Powerwall offerings?
Also has anyone had success getting a rebate in CA through
the SGIP/AES program? I know to qualify for SGIP one needs
to demonstrate load shifting as opposed to (or in addition
to BB).
There
seems to be an offering from Solaredge (Storedge), but it is
not clear their optimizers work with the 96 cell Sunpower
X21-345, for example.
I
am convinced that smart storage will become more important
over time, and I would like to use this customer to “get
smart”, and prepare for future business of this sort.
Any
practical knowledge would be greatly appreciated. I am happy
to exchange information on commercial demand management
offerings.
