This allows you to use a half-cell for control. This allows all of the controls for the system to be contained in one NEMA pole mounted enclosure, reducing wiring, installation, and setup times. There are losses inherent in any system. In a solar powered system, that same inefficiency can cost hundreds or thousands of dollars. By reducing those losses, the overall systems can be smaller, with fewer panels and batteries.
Fewer components equals lower costs and higher reliability.
More reliability means less time and money spent on repairs and parts. In a typical CP system, such as for a well head, you might need 3 amps going into a 1.5 ohm groundbed. With most systems or controls, that means that you need to come up with something that will apply 4.5 volts. With our controls, you can use a 12 or 24 volt system, and the CP control will convert it down to 4.5 volts with almost no losses. Ok, so now you have your 6 volts system feeding a 1.5 ohm bed.
