BG111844034 This is a typical PWM controller. The panel too small to be 200W, it is probably 20 Watts, so am MPPT controller would not make enough of a difference to make the high purchase price worth it. I use PWM controllers with my smaller (25 Watts or less) panels and MPPT worth my large panels.
