Dear Forum, my solar system is fixed with a 30amp SunMateSolar charge Controller and a 200amhr 12 volt battery. When the bars are full on the SunMate Solar (SMS) Controller it displays 12.7 volt as full battery. I have an idle smaller 20amp Controller, if connected to battery for testing(I don't have a digital tester), it displays 12.9 volt as the same battery voltage. I use gel battery.Which one is correct please and why the difference? Hope nothing is going wrong here then?
