Dan, you certainly can graph individual shunts in OpticsRE. They are
located under the "Battery" tab, lower left from the main dashboard. By
default, the shunts (i believe) are labeled A, B and C respectively, but
you can name them anything you like. I suggest "Inverter" for A, "PV" for B
and "Wind" for C. If you have the shunts wired correctly as per the FNDC
manual, power through the shunts will add and subtract and net the correct
values (as long as you are using the appropriate resistance shunts (and the
sense wires are oriented in the correct polarity as per the manual).  If
you are using a backup AC generator and it is being utilized through the
inverters charger, then shunt A will reflect the values in either direction
(both charge and discharge, to and from the battery bank). Aside from
calling Outback, you can catch me off list and I can explain. I also second
Johns comment about the quality of internet connection, its quite important
for Optics to get good data into the database, especially if you are
writing any parameters to the equipment.
