The Eco-Worthy MPPT has a rated input limit of 42 volts of panel Voc (total of Vocs of the panels in series) this is a lower amount than most MPPTs are rated for. 100Voc is more like it. Voc of a 250w panel is near 40v so two of those in series would be 80voc.
Each 12v panel has a Voc near 22 volts so two will fry the Eco-W by going over 42v (in theory--and why take a chance just because some guy got away with it?)
So if you put the panels in parallel to keep the voltage at 22, why have MPPT which gets any real benefit from high voltage as when the panels are in series (it then uses its buck converter to get the amps up to speed)
In parallel you might as well use PWM and not have any worries about Voc etc, just make sure the total amps expected from the panels is under what the PWM controller is rated for in amps and allow a 20% margin.
EG with 16 amps expected you should use a 20a controller.
How much is expected? Use panel wattage/130 x 8.2 = expected amps
Two 150s is 300 so 300/130 x 8.2 = 18.9 so you need a 25a controller to get the margin required. I would use my Solar30
