Is there a reason that Shunt C is disabled by default?

Postby bear_essentials on Sun Feb 26, 2017 8:26 am

Newbie question.
I have a factory pre-wired flexpower Radian 8048A system; with 2 Flexmax CCs. I notice that shunt C is disabled, by default, in the wizard.
Shunt C is however wired in the GSLC to the second charge controller, so I changed the wizard setting for shunt C to "Charge controller".
Did I do the right thing?

Any shunt actively being used by a device must be enabled.
If a shunt is not being used by a device it should be disabled.

So then why was the shunt not enabled coming from the factory, since there were two FM80s pre-wired into this system?
