I'm swapping out a Midnite SCC for a Victron and am not sure about the Battery negative and PV-. On the Midnite if I recall they are internally bonded but in the Victron I don't believe this is case. Do I need to wire the PV- directly to the SCC and also have a B- cable now from the negative battery busbar? Right now the PV- is just going to the "ground" busbar where PV-, B-, and chassis are all connected which I am thinking is no longer proper. This is for stationary installation.
