Hello
Recently purchase from ebay this item
LCD 10/20/30/40A 12V/24V MPPT Solar Panel Regulator Charge Controller 3 Timer KJ.
Start to wonder if this is true mppt regulator charger,after reading more from they website came across this sentence
( MPPT+PWM charging mode(Controller Provided MPPT Maximum power point tracking Function,charging mode is PWM ).
Is there such a thing MPPT + PWM in Solar Panel Regulator Charger,can both MppT ,PWM work together.
I thought mppt does charging of the battery.
What is purpose having pwm when mppt is the one that doing the work.
