<p>I don't connect to the HUB or Mate if I don't have to; both to
avoid issues with the customers changing programming, but also to
save the customer money. However, the #1 reason is that when all
the equipment is interconnected, it is all dependent. A failure
in a comm cable or single piece of equipment can cause all the
controllers to shut down. I just don't think the benefits of com
connection out weigh the loss of redundancy. I have many systems
with multiple charge controllers, and I have seen everything from
a bad temp sensor to a single failed controller take the other
controllers off line too. Without the interconnection, a failed
controller will just drop the system to half power, not to zero
production. <br>
</p>
<p>This isn't just with Outback, I follow this reasoning with
Midnite and Magnum as well. I often mix equipment (Magnum
inverter, Outback Controller) so comm connection isn't a
possibility anyway. We might be missing some bells and whistles,
but our systems stay operational in more situations. Basically
I'm not happy enough with any single manufacturer to give them a
monopoly with my designs. I've always built our systems with the
best equipment we can get for that particular situation.<br>

existing conduits is an attractive proposition,
making the FM100 a desirable approach. I now have
to figure out if I can add the FM100-AFCI (which
is apparently the only version available) to a
system with three FM80s, and if I do, what do I do
with the existing GFDI breaker and how do I
arrange the DC bond? There is a lot to consider
here.</span></p>

<p class="MsoNormal"><span>BTW, I was told by a tech
support person for an on-line sales firm that the
original FM100 did not have the AFCI but those
units have been discontinued. Now all FM100s have
the AFCI capability. I am weighing if I want AFCI
if it is not required. My territory includes
central California wild lands so I suppose I
should take advantage of any fire safety means at
my disposal...</span></p>
