Test Method PWM vs MPPT ?
I might get a chance to compare MPPT with my PWM on the set of two 100w panels. I get 12.6 (Isc) now with PWM so that is the "standard" I was thinking of a quick connect set-up to swap controllers...

Just finding a place to jump in~ carry on~
Well, I now have the two Controllars.
For those who see on EBay parts from HK direct to your home, it works.
12 days from order to del. I ordered the PWM Type 20 (20A 12V/24V)working voltage12v24v Rated charge current 20A Rated load current 20A @ $16.98 today to my door. No problem with Customs whatsoever.
Now, being back home, 150 miles from the RV with two Deep Cycle 12v Die Hards, no way for testing of the $49.95 MPPT and the $16.98 PWM that I now have in hand.
Me thinks from reading this thread, the small stuff will have to be bought from HK. China Post(Air Mail) Shipping on small orders of panels must be through the roof.
Reading this thread, from a novice point of view, makes me wonder if the highter priced Controllars are all, skies the limit for pricing?? Smoke and mirrors for free.
The new 20A PWM from HK direct, looks awesome but only about half the size and weight of the MPPT. Seems less guts in the PWM, how would I really know. Anxious to see how the (WORKING MODE) LCD acts. I will say the out side looks quality built.
