I talked to SMA tech support. They said the 5.0
and 6.0 models were compatible with AC coupling.
AEE supplied the SI 485PB NR Piggyback card with RJ 45 cable.

Well my supplier was not aware of any additional
part# for this purpose. Nor was their anything
in their manual stating compatibility.
Part# PLEASE, It does seem short sighted of the
company who pioneered AC Coupling to no longer
provide us w/ equipment for said ACC.

What are the limitations of the new SMA inverters?

Â
As a caution:Â The TL22 inverters have been
discontinued. The TL40s have some
limitations as compared to the TL22s, in my
opinion. You may still find TL22s on the shelf.

Subject: Re: [RE-wrenches] Aquion Batteries
Â
I have dual Sunny Islands & dual SB 4000TL22US
 w/ 20 stack on one and another site w/ theÂ
Aspen 48MÂ w/ Schneider. I will say this; cost
per amp hour of storage  sucks w/ the Aquion
batteries. Both my client and I feel, that the
batteries, despite there size have very little
capacity. The â30â%DOD, that I have the
SIs set to start the Gen set, charges the
stacks OK but one gets better performance from
 charging w/slower solar source. The Aspen48M
is ~ 42X28X42â @563 AH of capacity, UnigyII
2000 Ah ~ 42x40x6â tall. Batteries are
defiantly temperature sensitive, operating
should be ~ 60*. The set up w/ the SMA
product, adds additional cost due to the
required  BM200 AND  the Sunny Island
Interface Device, and the SM100 unless you are
buying theAspen48M which comes pre wired.
(Aspen 48M which comes thru w/ the sensing
module installed). It is quite helpful, if
this is an off grid install due to the fact
that the BM200 needs and when things go south
Aquion can toggle the unit off site and help
w/ configuration &Â upgrades, to be connected
to the internet. This install also needs the
correct firmware to be installed on the SI
which when  was delivered, the firmware Â
would only load into the master then shut down
the system. Had to reconfigure as 2 separate
units, load the firm ware and then reconfigure for 2 phase.Â
I have spoken to the manufacture re/ lack of
capacity and was told that must be my loads
. NOT.Â
>I would suggest that despite their hype
these are quite expensive and require quite a
bit more of labor IF you are wiring the un
sensed stacks. And there is definitely a
learning curve if you are using the SI.
My own system and what I prefer to push IS the
SMA SI w/ the SMA SBs (make sure that you get
the TL22s as the newest SB is not compatible
for â AC couplingâ in this configuration)
w/ the Unigy II/MK line. (same battery) These
have buss bars, stack vertically , the
interlocking stacks is perfect for earthquake
locations. AND are totally recyclable.
Pictures  of the SMA install & insights of
battery installation available, contact me off line. TUMPÂ

We had a customer request them but once we
found out how many it would take, he decided
on the deka unigee instead. l dont like
running my OB's at such a low voltage as they
seem to get hotter due to the higher current.
Some of our other product lines don't even
reccomend aquions due to that low voltage,
suggest asking your inverter manufacture too.

Hello Wrenches,
I have a client who is going to take the
plunge and buy a set of Aquion Batteries. They
look pretty good on paper, but I'm not sure
how well an inverter would function at the 40
V minimum. Does anyone have experience to
recommend them or warn against using them?
Thanks,
Drake
