Rover 12V/24V 20A Charge Controller with MPPT- DC Input Solar Controller for RV/Marine, Auto Parameter Adjustable LCD Display Solar Panel Regulator fit for Gel Sealed Flooded and Lithium Battery

What are the advantages of Renogy MPPT technology?

Rover's advanced MPPT technology tracks solar panels' maximum power point in real-time, ensuring peak efficiency &outperforming PWM controllers. Features wide input voltage (up to 100V), compatible with 12/24V systems and high-voltage/multiple panels

What type of protection does the Rover MPPT Charge Controller have?

Battery: Over-Discharge, Over-Voltage, Reverse Polarity.

Load: Overload, Short-Circuit.

Controller/PV: Over-Current, Short-Circuit, Reverse Polarity, Overheating.

If I have 2x200W panels which of these MPPT charge controller will be good? 20A or 30A ect..

If you connect these panels in series to a 24V system, the 20A model would be acceptable. But you would need a 30A controller if you connect these two solar panels in parallel to make a 12V system.
