I have a smart shunt and a smart solar. The shunt seems to be reporting the correct voltage, but the smartsolar is all over the shop- during the day it’s saying the battery is 14+ and at night 8 volts. The battery voltage, according to the smartsolar, is always out of range to charge- so it never charges the battery from solar even though panel voltage is 60+.

Why would there be such a wide discrpancy? I’m camping right now and this is the first time I’ve seen it, going to get a multimeter today and test.
