I am going to display my ignorance here, so be ready to laugh. How do I tell what kind of controller I have?? It is built in to the portable panel -- but I bet I could un-attach it, with enough brute force. ;)
I'd be willing to bet it is PWM since it came on the panel. My recommendation, get a good MPPT (I chose Victron SmartSolar) and put it at the batteries. Then disconnect your panels from the OEM controller and run them directly to the MPPT controller.
One caveat. I have not been able to find a good weatherproof MPPT controller. You will need to protect it if it is going to be exposed to the elements.
