Voltage sense line/temperature sensor wires

I have the MS PWM; I ran 14 gauge wires for the voltage sense line when I rebuilt the wire/cable setup between my batteries and their clients. The distance is about 5-6 feet.
The temp sensor had sufficient wire length so I didn't need to add wire. The factory sensor has 18 or 20 gauge wire, if I recall.

As there is no load on the voltage/temp sense wires, I'd expect you can use the 22 or 24 gauge POTS (Plain Old Telephone Service) wire.

The only issue I can see is that the POTS wire is solid where stranded may be better for longevity at the connections and it is a bit easier to route.

Thanks for the info,

This phone wire will be used ONLY for the senors etc for the MS MPPT CC, manual states I can have a second set of battery's hook up and read via the CC/invertor.

Not for primary power! But if you want to use them for remote voltage sense, they should work OK. The V-Sense is high impedance, but there might be some error in the temp sensor. Any I have ever played with or built requires calibration at the end of the wire that's being used. Can't say how severe the error though without the equipment spec's, particularly the thermocouple.
