If you use a solar panel and a mains power supply (and no battery), connect the red wire to the positive pole (Vin) and the blue wire to the negative pole (Gin).
If you use a 12 V lead-acid battery PWR IN > 15 (and no solar panel), connect the yellow wire to the positive pole (Batt +) and the grey wire to the negative pole (Batt −).

For powering, you can use a solar panel and a mains power supply (such as QMP201C or QMP213), or a battery.
