Little confused, 12v vs. 24v solar
I've got an existing 12v solar array with 1x 130 Watt and 2x 80 Watt for a total of 290 watts @ 12v, fed to a 30 amp MPPT controller (Rogue MPT-3024). I bought what I thought was going to be a 200 wat...

Not sure how well the power point tracking will work with the variety of panels.

This is a concern.

Although the individual PV modules of an array need not necessarily be of the same make or model, you will
achieve better tracking performance from an array in which all of the modules have the same maximum
power point (V mp ). This is best accomplished by choosing modules of the same make and model. Even if
modules are not identical, be sure that they each have the same number of cells. While it is possible to wire
modules together with varying numbers of cells, this will degrade the output of the entire array.
If you don't want to send the panel back, I would put it on the Roque and run that in parallel to the batts with a new PWM for the existing 12V panels.
