Installing an inverter with a Dual Battery Isolator / Relay to bypass smart alternator

I plan on installing an inverter with a Stinger 200 Amp Dual Battery Isolator / Relay www.stingeraustralia.com.au/product/sgp32 connected to an ignition source on my sprinter the D+ terminal to run a 1000w inverter that I want to run when the car is running only.

Will this work?
