I have a 20 amp MPPT controller that might work but not sure as the info show 12 or 24 v operation. Is this considered a 24 v system??
That spec usually means it will charge a 12 or 24v battery system. What you need to research is whether it will take the panels' voltage, which is more than 24v. However, 20 amps isn't going to work as two of those in parallel will be 600 watts or about 50amps to batteries at 12v. It's possible it would work on a 24v battery system, but that's not what you have. You may be restricted to just one panel with that controlller.

there will be several 12v panels of about 360 watts total which could be wire in series to make 24v system but do to shading issues my stay parallel.
I don't know where those fit in.
