How can I setup my C Series for 12V and/or 24V?

Issue:
C Series setup for 12V and 24V

Product Line:
C35, C40, C60

Environment:
C Series installation

Resolution:
The top potentiometer has to be setup for the Bulk stage of the battery bank. This value is usually at a much higher voltage than the battery bank. So for a 12V bank, this value is usually set up to around 14.5V. Furthermore, if using a 24V battery bank then this value is usually set to 29.5V. See picture attached to this solution.
The bottom potentiometer is the setup for the Float stage of the battery. This value is usually setup to a lower value than the bulk but higher than the battery bank. So for a 12V battery bank this value is usually set to 13.5V. Furthermore, if using a 24V battery bank then this value would be set to roughly 27.0V.

Cause:
Many times the customer does not know where exactly they have to setup the voltages on their C Series charge controller.
