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. <br><br>

Part# PLEASE, It does seem short sighted of the company who pioneered AC
Coupling to no longer provide us w/ equipment for said ACC.<br>

As a caution: 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.<br>

<b>Subject:</b> Re: [RE-wrenches] Aquion Batteries<br>
<br>
I have dual Sunny Islands & dual SB 4000TL22US w/ 20 stack on one
and another site w/ the <b>Aspen 48M</b> 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 “30”%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 ~ 42X28X42” @563 AH of
capacity, UnigyII 2000 Ah ~ 42x40x6’ 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. (<b>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 &
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 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. <br>
I have spoken to the manufacture re/ lack of capacity and was told that
must be my loads. NOT. <br>
>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.<br>
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
“ AC coupling” 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.<br>
Pictures of the SMA install & insights of battery installation
available, contact me off line. TUMP <br>

<dd>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.

<dd>Hello Wrenches,<br>
<dd>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?<br>
