Hi Martin, This is a 13.8v system, run off batteries and solar cells, the reason to be able to monitor current, charging the batteries and current drain from the repeater system. I can monitor volts ok, just those damm amps running around.

Kevin, Is your rack on a single phase feed? If so, placing a current transformer in the black lead will give you a output current proportional to to the input. Put a resistor across it and use the voltage input to the controller. The downside to this approach is the controller will "talk" the current and label it "volts". Martin
