We have a Roller Team MH with a factory fitted 120w solar panel. This is connected to the battery via a PWM controller.
First question is, is there any benefit in changing the controller to a MPPT type which I understand are more efficient and can put a bit more into the battery.
Second question, are all MPPT controllers created equal? Ebay has controllers from £25 upwards. Are the cheaper offerings less superior than the expensive models.
Thanks
