[QUOTE="Occasional_panner, post: 436686, member: 7956"] Well you paid a reasonable price for it and the pwm will be just fine. BUT I personally hate A holes selling stuff fraudulently. Just confirm it and do this test [url]https://www.youtube.com/watch?v=YMFf0se1PqU[/url] Put the probes in the solar input as per pic on post 19, have meter set to volts(left side for dc, the volts on the right side is for ac) black lead in the bottom socket, and red lead in the middle socket. If the volts from the panel stay high then it's mppt, if it gets dragged down to slightly above the batt voltage then it's pwm. Mppt uses a dcdc converter pwm just connects direct to battery and pulses off to keep battery volts from overcharging. [/QUOTE]
