  • PWM just shut energy on and off from the panel. They have no inductors. [1]

MPPT Controllers

  • $60 for 40A - [2]
  • $76 for 60A, true MPPT - [3]
  • Inductors are visible with transparent case - I like it! [4]
  • This one is a cheap Ooycyoo - [5] - not transparent if it is MPPT.
  • True MPPT by reviewers - [6]
