Yes I had also heard from Outback that AC Coupling not supported.
Too bad because the AC coupling load center was slick setup and integration.

Howdy wrenches,
Does anyone have any experience with disposing of the Aqueon battery stacks?
We have a number that have failed and our local waste station is balking,
regardless of how much hand-holding we provide and specifications, MSDS and
manufacturer info we supply.
We have been referred
Cells, even in a string /buss bar configuration, a cell will fail eventually,
either a 6 volt, 12 volt or 2 volt battery Systems that are designed like this,
w/ 2 v cells I can take the offending cell out of the system, jumper the bad
cell, and the system will function perfectly fine at lower vo
It is extremely rare that a 2V cell like Trump is refering fails causing
loss of power to the home. There is often plenty of warning that an
informed offgrid owner would have that something is wrong. The last point
is the inverter and charge controllers have enough range that they can
operate the s
That's true for 48 v systems but not 24v.

In the past month I have had Outback and Sunny Island customers running
down a cell. Sunny Island is reconfigurable to manage the situation
better.

So you're willing to risk total system shutdown if a single cell fails?
It just seems like a big risk even if the batteries are considered
highly reliable. I always planned to minimize the risk of failure
causing a power outage. A buss bar arrangement with more strings
provides redundancy an
Larry,
I recommend considering retrofitting the SolarEdge “StorEdge” Li-ion battery.
It’s a high-voltage battery on the PV side of the inverter. We have a few out
there now for a few months without a problem. Really like the design concept of
the storage on the PV side, increasing system efficie
If I lived in CO [or one of the other state where recreational MJ is legal], I
would be soliciting grow-ops for GT system installations.
Those folks have cash to spare & huge electrical loads. That in itself, could
be an entire business plan.

When I have a call like this, usually they do not have an understanding of

Hi all
I’m hooking up a generator with a built in 5 minute shutdown delay.
The mate3s sends shut down signal, inverter disconnects from power. But since
the generator keeps producing power the inverter reconnects after. Few seconds
and starts charging again.
The mate3s has a new feature “ac

buss bar. 2 volt EX1400 1K amp hour batteries work very well good warrantee.
all the fusing & interconnects would be eliminated. MORE AHs = less
interconnects, always the correct way to go!
