Mostly, no. The solar monitor just has a shunt for the solar and not for the rest of the rig. It is nice to know the amps the solar is doing at any time, but the solar AH info is fairly useless.
The Trimetric has a shunt that sees everything including the solar. the solar monitor shunt( if any) is upstream from the Trimetric.
There is a new controller monitor (ISTR called the Kid?) which has the shunt arranged to subtract solar from "all" and you get the whole story--forget exact details.
So take the Link with you to the new rig.
Some solar controllers have a built in ammeter and display so you don't need a shunt etc. Tthat gives you what you want to know about how the solar is doing without having to pay for a solar monitor at all. The $35 Solar30 PWM has that and so does the $102 Eco-Worthy MPPT for instance. Works great.
