Hi guys, i bought an ammeter/voltmeter off ebay, but I cannot work out how to connect it in my circuit. I want to know how many volts and amps my Solar panels are producing. Can any body help? Below is 2 links showing the unit and the wiring diagram. I have wired ammeters and voltmeters in my cars before, but I just cant get the gist of this. Thank you guys

Two wires go across the supply/power terminals, the yellow is connected across the low value meter shunt resistor for current which is placed in series with the power to the solar panels.
It also appears you need 4.5v - 30v max power for the unit itself?
Max.
