Just installed Smartsolar 100/30 with no panels hooked up. (Nothing connected to pV’s) also have networked BMV 712 with temp sensor. With no panels the voltage under solar shows .01 volts.
Should I be concerned about this? I have read a previous poster after reading all night about this but he had panels hooked up with a fuse.problem.
Here no pv connections.
Any insight regarding this?
thank you
In my opinion this is completly normal. I'd be more concerned if you saw amps going in, not voltage. Small voltage can appear for a number of reasons, namely because of parasitic capacitance in input stage mosfets.
@JeffreyB, this is only 1/100th of 1 volt that it's showing, so there's nothing to worry about here. Given that the "pv" and "battery" terminals aren't fully isolated from each other, a little ghost voltage between the input/output is entirely normal to see when one or the other isn't connected.
