Can a 10 Amp Solar Port Be Used With a 20 Amp Charge Controller  

Question:

If I have a 20 amp mttp controller, do I need a 20 amp port? Or will the 10 amp port work. Running 2 100w Renogy panels. Thank you,

Expert Reply:

The 10 amp port # FSPINS-BS should only be used with the portable panels, which shouldn't be above 10 amps. So, assuming you're using the 20 amp charge controller for your roof panels you'll be fine because they'll go directly to the battery without touching the port.
