My 2018 Palazzo came with a single 100W panel and a PWM-30 (30amp) controller. If you verify what size controller you have and, if possible, what gauge wires they pre-installed then Go Power or other manufacturer could recommend max panel size and/or quantity.
I added a complete Go Power 680 system and Li batteries and then rewired the factory stuff to my Chassis batteries (since flooded batteries have different charge parameters than Li and use a different isolator)
