I bought some DC breakers to use as a disconnect, however I plan to install them on the negative cable because I have fuses on the positive side and no room beneath the fuses to install another inline device. I mainly want to use it as a disconnect vs. an OCPD. The terminals are marked line and load and I intend to connect them such that current flows from line to load, which on the negative side of things would have the inverter connected to line and the battery bank connected to load. The inverter/charger is capped at delivering 30A of DC charge current so I was less concerned about flow in the other direction. Anyone have any advice on this? Are my assumptions about current flow correct? Should I be using a DC breaker when flow is bidirectional? It's not absolutely essential, but it would be nice to be able to completely disconnect each inverter from the battery bank to do maintenance or troubleshooting.
