New controller? Looks like it was added today.

The more I look at that monitor attachment to a shunt, the more confused I get. I can see how it would act like a Trimetric. The blurb says it measures amperage or energy.
I can't see how that makes it differentiate how many amp hrs went into battery charging vs just running things as 'extra solar' in the afternoon.
And I can't see how, with the rest of the rig across the shunt, how it would know how much is solar and how much is the rest of the rig, anymore than the Trimetric can tell how much of what goes across its shunt that day was solar.
Meanwhile I am now confused about what all those solar monitors are doing now 'the old way' Some have shunts and some don't. Even my $34 Solar30 PWM controller with no shunt has a readout for amps and another readout for accumulated AH. Where does it get the information to provide those readings? I ASSume it can't tell how much of that is going to the battery and how much to run other stuff as well.
Plus it is not like the batteries are just soaking up solar charging all day. They also have draws of varying amounts at the same time. You need a shunt to be able to count AH going both ways and get a net amount.
I hope to figure out some of that when I get to use the controller ammeter/AH upstream of the Trimetric shunt later this Spring. Maybe it will all make more sense then what this new Whizbang gizmo does :(
