Re: [RE-wrenches] Ilsco Insulated Tap Connectors

[cwarfel]

Hello Wrenches, I am trying to redesign a couple hundred watt load 
off-grid system by first focusing on the battery technology. The Li 
based battery "packages" I am aware of are essentially for a residence, 
which is too large for this application. Can you recommend a 
manufacturer of Li batteries that can be used in an off grid application 
that had safe battery charging capabilities as part of its product 
line.  Currently, 2 Trojan L16s are being used, which, while is a fine 
battery, is limited in its depth of discharge.  Thanks for any 
info/help.  Chris

I'll x2 what Ray saysunless it specifies AC or DC then the voltage rating 
applies to either.

Simpliphi batteries, lithium ferro, are safe but a little expensive.

Re: [RE-wrenches] Ilsco Insulated Tap Connectors

[Dave Angelini Offgrid Solar]

Discover AES has some very nice Li-ion batteries that work directly with
Schneider Electric and soon Outback.

http://discoveraes.com/

Almost all of the LFP batteries are selling for about $1,000 per usable
KWH. They are expensive but if you do the math, and pick a company that
will be there, they could outlive you.

[RE-wrenches] top of pole with no galvy

[Bruce Erickson]

Hi All,
I have a super particular customer who needs a small top-of-pole rack, but will 
not accept anything but aluminum or stainless (or bronze or titanium or . . ). 
No galvanized steel! Anyone have a lead on a rack manufacturer that has all 
aluminum pole tops, like Unirac used to make?
Thanks.

Re: [RE-wrenches] top of pole with no galvy

[Ray]

That's funny, Unirac were some of the weakest TOP mounts I ever used.  
Better be sure and get stainless pipe for in the ground, because the 
pole right at the transition into the ground is the first thing that 
will rust.


Another idea,  it might be easier to find all Aluminum racking in a 
regular ground mount, and set it on concrete Sona tube risers.
