Hi Dave/Wrenches
We've been using the SW with both the 2.5 and the 2.0 frames on most of our
systems lately. The 2.0 frames work fine in traditional roof mounts, as long
as the racking system chosen has good options for cable management. We did
a DPW TPM with them last year where I came away in a
Greetings,
Does anyone have experience with Iron Edison Batteries for an off grid
application?
They claim "excellent and reliable performance for 20+ years"
Thank you,

Phil,
Their cycle rating is far less than Hups or Rolls when you compare specs. I
understand their self discharge rate is atrocious requiring a substantial
portion of the charging source(s) to be allocated just for this.
I have heard the sales pitch that they last forever, but if you live off g
I don't know that there are any new sources for NiFe batteries and the last
ones were either from China and Hungary. While they were advertised as new,
some at least arrived in obviously used condition. They are reputed to be
nearly indestructible, but I've seen piles of used recycled ones. They do
Dan, I agree, the batteries are a major factor here and as usual much can get
lost in translation when details are left out. My bad, I'll try to bridge the
gap a bit...
What we have here is a complete up and running off-grid system; -the batteries
are Surrette 2YS31P (2V each x 24 = 48V
Thanks Bill,
They are presumably making these in Lakewood, CO

Nathan,
My original choice was going to be Trojan.

i am not sure what the advantage is of running in HBX mode? why not simply
grid-tie this where any surplus power (over local use) gets sold to the grid?
also the vfx's can be sent into ob for upgrading to gvfxs. no need to buy new
inverters.

I think he has off grid inverters that aren't capable of feeding the grid so
there is no reason not to use the power unless he wants to purchase new
inverters.

Todd,
I agree with using the gvfx inverters assuming he's generating more power then
he is currently using. He said the system was sized for the current load so it
seems like a waste to let such a large battery bank sit at full charge.
Outback does upgrade the boards for free most of the time
It is a Colorado company, but they are importing them from China. I've met the
owner.
My understanding is the plates do not deteriorate, but the electrolyte needs to
be replaced every 5 - 10 years, so technically you would never need another
set, just KOH.

I have looked at these batteries and they are very expensive for the kWh I am
also conserned with the charge/discharge rate. I have a project that I am
thinking of using these for, in that the kOH stays KOH through out the charge
discharge, which meand they will not freeze like lead acid. So f
I just finished today a 2.0 frame job. the wire management added to the
problems, I used Snap N Rac rails and droped the wires into the wire way, I
am concerned with the small section and I made my own optimizer mounts to get
more clearance below the modules...

I made a few alignment blocks that allow a 1" circle on the lag bolt centers to
allow for the critical alignment of trays. However they cost $7 each to be
made in a CNC shop. If there were a call for these it could be extruded. and
maybe $2 each. But I agree the SiE is a solid module

Darryl,
What type of alignment blocks? Solid off centered blocks? or "C" shaped
'L' feet like these Sundmodo products?
Ditto Darryl's comments, The measurements are much more critical for the
trays than most other standard modules.
