Hello All
1. I want to avoid AFCI unless mandated. Will this be defeated if I
don’t run the leads through the sense coil? (There is an AFCI and non-AFCI
version but I can’t seem to find the non-AFCI version anywhere.)
* Yes, you can bypass the AFCI by simply not running the PV conductors
through the sensor coil
2. I noticed the manual indicates you are not supposed to mix the FM100
with the FM80 or 60 in the same battery system. This negates it for one
project I had in mind. I am curious as to why this is. Anyone know?
* Here is a link to an App note that covers this situation
*
http://www.outbackpower.com/downloads/documents/appnotes/fm100_fm80_app_note.pdf
*
3. Will the FM100 work with a standard hub?
* Yes, both HUB4 and HUB10.3, but firmware updates take almost an hour
on the HUB4 because it’s slower.
*
4. I suppose this unit requires a 125 amp breaker. If the PV array
cannot support that full 100 amps I might down-size the OCPD accordingly.
Anyone contemplate this question?
* Depends on the application, but all of our prewired load centers and
systems come with 125A breakers.
I hope this helps take care all.

Friends:
I have occasion to try the FM100 charge controller. I am wondering of anyone
had found any quirks with implementing this device. I have a few specific
questions:
1. I want to avoid AFCI unless mandated. Will this be defeated if I don’t
run the leads through the sense coil? (There is an AFCI and non-AFCI version
but I can’t seem to find the non-AFCI version anywhere.)
2. I noticed the manual indicates you are not supposed to mix the FM100 with
the FM80 or 60 in the same battery system. This negates it for one project I
had in mind. I am curious as to why this is. Anyone know?
3. Will the FM100 work with a standard hub?
4. I suppose this unit requires a 125 amp breaker. If the PV array cannot
support that full 100 amps I might down-size the OCPD accordingly. Anyone
contemplate this question?
Thanks in advance.
William
