Correct on both counts, but the often-called inverter is more correctly an inverter-charger: It can convert (invert) 12vdc from the batteries into 120 vac when not plugged into shore power or on the generator, OR it can charge the batteries when plugged into shore power or on the generator. The Ethernet cable is connected at the other end to the inverter on-off switch near your fuse box and other electrical switches and readouts. Turning this switch off only turns off the inverter function; the charger function is still active (with shore power or generator) UNLESS you change the position of the little slide switche actually on the inverter-charger to the right of the blue cable to the center ("DC off") position.
The battery disconnect shown is a latching relay, meaning that it can stay in either on or off position with no further power. It gets a short shot of power to change its position by the momentary switch also on the electrical panel (probably the monitor panel, but I'm not positive about your model). Pushing the top of the switch is probably the "on" position, pushing the bottom is probably the "off" position. The switch returns to its neutral center off position when you release it, but the relay stays in the last activated position until you change that.
