The smaller Smart MPPTs like the 100/30 or 50 do not include remote shut down switches needed to connect to a BMS. They do have VE direct ports that you can connect an optional VE cable that allows for remote shut down, but when you use this you can not connect a Bm712, ccgx, or Venus GX. How do you get around this road block to have both a remote shut down in a BMS over charge alarm and also connect a Bm712? The lowest cost Smart MPPT with a remote switch is Smart 150/45 at $200 more than the 100/30 unit. Does the BM712, CCGX, and Venus GX have a port to connect the BMS lead to to switch off the MPPT?
The other option is to use a BP65 between the MPPT out to battery. So my question here is it save to use the BP65 as a shut down to the battery with the PV still charging the Smart MPPT 100/30 or will it damage it?
This is for a RV installation.
