Re: [RE-wrenches] Ilsco Insulated Tap Connectors

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.

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

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

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

Re: [RE-wrenches] Ilsco Insulated Tap Connectors

2018-06-02 Thread Ray 
I pulled up the Ilsco site.  They are rated to 600 volts.  That voltage 
is AC and DC, unless it specifically says AC only.  We've used them for 
decades with DC.  Check your voltage rating for THHN cable: it does not 
say DC either.


Ilsco is also one of the few manufacturers to make flex cable rated 
connectors.  They have blue caps.  This is what we should be using when 
using higher strand count cables like Cobra X Flex.

The plastic is not thermal set and it will distort if pressured 
against the side of the box.  This has never been a problem for 
interior wiring only in the solar case outside.

I have heard AC DC no difference.  However, I have experienced failure of
these connectors via insulation softening in J boxes on the roof.  The
plastic is not thermal set and it will distort if pressured against the
side of the box.  This has never been a problem for interior wiring only in
