Wonder if the Kilovac Automotive Relay 12-900V High Voltage DC Contactor 500+ A carry, might work, one on each mppt output.

I've been using them on the inverter for a long time, have had no trouble breaking 600 A @52v many times, I know your voltage is higher, but might be worth a try as the cost had come way down from what they used to be.

That with Phil's suggestion of a beefy SCR and load as worst case scenario backup.

Just a thought.
