.
I bought a new Motorhome last year (breaking my heart to see it sat unused on the drive).
It has a 100w roof mounted solar panel with a Truma controller.
It enables me to set the type of battery and the percentage charge that goes to the battery if more than one battery fitted. (I only have one battery, (liquid), so it automatically sends all the solar charge to that).I understand the first 2 settings and have set them for the battery type ie liquid, and charge allocation. The 3rd setting allows me to set a PWM charging frequency (whatever that means) of 25Hz (preset), 50Hz or 100Hz. How do I find out which of these PWM settings to use as the handbook is not helpful on this? Any advice you can offer will be very much appreciated.
