I have a CM2024, PWM Solar Charge Controller fitted to my motor home but was not provided with a user's manual by the dealer. I emailed the manufacturer in China but received no response. Can anyone assist with a scanned copy of one or provide a link for me to download a copy. I would be most grateful

There are a couple of chances here:

instruction manual - AA Solar   or   User 'S Manual

Hi William

Do you have a problem with it ??

Cheers John

I suspect the 3024 is very similar to the 2024 but has a temperature sensor and can handle more current.
