ATEngeus CD09 Variable Speed Compressed Air Duster

Hi Professor Rick. I have a question for a smart man.
What size MPPT Charge Controller do I need for 400 watts of solar?
Charging a 2048wh LiFe Battery to the full 400 watts solar capacity?
A 20amp MPPT is not enough.
Is it okay to just get a 60amp MPPT and be done with it as I might add more 200W solar panels?
Thank you,
Tom - Dallas

Is it powerful enough to clean air filters?
