Switches have the ability to pass monster Amps during an engine start.

Solenoids with 2000A ratings will be expensive and still not reliable.

Buses have proper amperage knife type cut off switches that might be set up with a remote pull OFF cable , and manual reset.

You will probably fry the alt disconnecting a running engine , but it might be worth it ?
*From the size of the bank, it sounds like a house bank, not a start bank, so the high current draw might not be an issue.*

Many experts advise that you connect the alternator directly to the battery.* If you do this, you won't fry the alternator when isolating the battery bank with the engine running.* If you need to stop the charge into the bank, you can stop the engine and remove the fuse.
