boB,
It looks like 3/0 or 4/0. It is a short run.

I have seen this on my last 3 MX60 controllers and it is very
frustrating and looks to be a design flaw. I can calibrate the
meters to be accurate at either the Absorb point OR the Float point
but NOT both!! Not only that but the meter calibrations tend to
drift a bit in just a matter of days, just .1V not a big deal but
anymore than that on a 12V sealed battery and it could be an issue.
I spoke w/Outback about this and heard a mumbled "Ahh, uummm, yeah
that is an issue". I'm guessing that you're seeing the same thing
and when you spoke w/your customer again and the meters all agreed
I'll bet it is because the MX was at the "line up point" of the
other meters (just like a broken clock being correct twice a day!).
The only way to live with this is to get the more important Absorb
set point right on and take what you get on the lower end. It works
and is usable but drives customers nuts when they have additional
meters. In my experience the Tri-mets are dead on.
Jeff, what size wire from charge controller to the battery are you
using ?? The bigger the wire, the less the
I*R drop and the less the voltage discrepancy ~should~ be, at
higher currents.
