We have a job under contract this summer with four Sunny Islands and
a Radian sharing the same battery bank. Even with the SIs protected
by 125A DC breakers, that's 850A of DC capacity that we have to buss
together. <br>
<br>
The Midnite bussbar in your link is rated 280A in its description.
That seemed pretty wimpy, given that a single Radian uses two 175A
GJ breakers with conductors paralleled, so I just called Ryan
Mayfield, Midnite tech support. As he understands it, the limit is
on the terminal strip, not the bussbar itself. He'll talk with Robin
about this and get back to me; if I learn more I'll share it here.<br>
<br>
Even the Del City bussbar is rated just 500A. Are there any
higher-capacity products available?<br>

Here's a new one I just found with Del City also: <a class="moz-txt-link-freetext" href="http://www.delcity.net/cartviewitem?item=80510DL&search=buss+bar">http://www.delcity.net/cartviewitem?item=80510DL&search=buss+bar</a>

I've used the Ilsco insulated distribution blocks available at electrical supply houses.
I've also made them out of 1/4" x 2" copper, and then used some weird way to isolate it, or bolted them to the breaker.

<pre wrap="">Hi All,
Where do I find buss bars for a battery parallel problem?
I've got to fix a brand new ( not me) system, that has 4 sets of L-16's at 24v.
Yea yea why didn't they go to 48?
So I want to use buss bars to parallel them, and looking for premade ones.
Thanks in advance,
Jay
