Solar Panel Series Vs Parallel: Wiring, Differences, And Your Right ...

If the manufacturer hasn''t clearly labeled the polarity of the solar panel, another approach is to use a multimeter to measure voltage. To do this, insert one multimeter probe into each of the MC4 terminals. If the reading shows a positive voltage value, it means the positive (red) probe is connected to the positive end of the solar panel.

Do I need to switch both positive and negative feeds from solar panels ...

I was in a discussion on an RV forum and the topic of whether to disconnect both positive and negative wires from the solar panels to the SCC is required. I guess it is per NEC code for houses, but not for RVs. While I''m all for codes, I would like to understand why it would be a good idea to break both wires in an RV application.
