The Wanderer was tested with a 12v nominal panel-your 320 is not 12v nominal. A PWM will give you 9 amps charging with it-an MPPT over 20amps charging...
There is no free lunch! You've already purchased one cheap controller that you're looking to replace. How much money are you going to throw away before purchasing a decent SCC?Thanks, I just need one that isn't expensive and does the job really.
Epever says that on some labeling. It’s pwm until volts from panel get high enough, then it runs the mppt algorithm. If it’s cloudy or early in the day and only 12 or 13V is possible it functions pwm because it can’t make 14.3V from 13V. Once sun rises a bit panel input will show VOC at ‘x’ Amps and battery input at 12/13/14+Volts and roughly VOC/13*x for amps (that’s not science- that’s a bad way of making a hopeful guess btw; that’s not a real formula for anything it just sometimes sorta works to guess so please don’t shoot me)the mppt controller instructions says it's mppt pwm mode
